Recently, one of my friends in Florida contacted me regarding iguana issues in his backyard.
He asked me to suggest a few air rifles that would help him get rid of his pest issue and prevent his backyard from getting damaged.
Owing to that call, I came up with the idea of dedicating an air rifle guide that talks about the best air rifles for pest control.
After all, there are several things to consider, right from their power to their noise.
So, if you’re facing the same issues as my friend, read on!
Things to Consider Before Buying An Air Rifle for Pest Control
Before I move on to discussing the best air rifles for pest control, let’s talk about a few things to consider.
These should help you make the right choice for choosing a good air rifle for the job.
1. Types of Pests & Suggested FPE & Caliber
Keep in mind that you need to opt for an air rifle depending on the size and speed of the pest.
Also, note that the best air rifle pellet for pest control also depends on the type of pest.
Another important thing you need to take care of is the muzzle energy, or FPE, of the air rifle.
If you’re unaware of FPE, it basically states the amount of energy that hits the target.
Hence, for different pests, you need different FPE.
Let’s take a look at the required FPE for each type of pest:
|Pest Type||FPE Required||Suggested Caliber|
|Rats||5 FPE||.177 Cal|
|Chipmunks||6 FPE||.177 Cal|
|Squirrels||9 FPE||.22 Cal|
|Iguanas||10 FPE||.22 Cal|
|Groundhogs||12 FPE||.22 Cal|
|Possums||25 FPE||.22 Cal|
|Raccoons||25 FPE||.22 Cal|
The FPE largely depends on two factors – the velocity and the pellet weight.
So, ensure that apart from looking for FPS, you focus on the pellets you use as well.
2. Sound Produced
Imagine if you’re about to shoot a pest in your backyard and the sound is so loud that your neighbors may feel threatened.
Trust me, you would want to avoid this situation.
Generally, air rifles have a noise between 74 and 90 decibels.
You may find some models on the quieter side and for pest hunting — those are the best.
For example, the Benjamin Marauder air rifle is one of the quietest air rifles in the market with 74-decibel sounds.
When it comes to the type of air rifle, you’ll find that springers are the quietest ones.
So, they’re ideal for hunting backyard pests too if you’re looking for quiet air rifles. (See this post for more)
3. Repeater Mechanism
It isn’t always possible to kill the pest in one single shot itself.
Sometimes, they may still be alive.
Therefore, you should look for an air rifle with a repeater mechanism.
A repeater mechanism allows you to shoot multiple shots before having to reload your gun.
This allows you to kill the pest immediately before they escape.
On the contrary, a single-shot rifle may allow the animal or rodent to escape before you shoot them again.
4. Easy Usage and Lightweight Nature
You would want to go for an air rifle that is lightweight, easy to use, and low maintenance.
When it comes to weight, most air rifles weigh around 6 to 7 pounds.
You can opt for those as they’re ideal for backyard hunting and easy to use.
What is the Best Air Rifle Choices for Pest Control?
1. Benjamin Marauder Synthetic Stock – Best PCP Air Rifle for Pest Control
If you’re looking for the best PCP air rifle for pest control, the Benjamin Marauder Synthetic Stock is the one.
This rifle offers a power-packed performance with its excellent velocity and accuracy.
Moreover, the air rifle’s velocity ranges anywhere between 850 FPS to 1000 FPS.
So, you can easily get a clean shot while hunting squirrels and similar pests.
The table below represents Benjamin Marauder’s velocity and accuracy with various pellets:
|Pellet||Energy (FPE||Velocity (FPS)||Accuracy|
|H&N Baracuda Match (21.14 Grain)||33.34 FPE||843.85 FPS||Great|
|JSB Jumbo Exact (14.35 Grain)||28.28 FPE||941.99 FPS||Best|
|Crosman Premier HP (14.3 Grain)||27.82 FPE||935.83 FPS||Great|
|RWS Hobby (11.9 Grain)||25.4 FPE||980.30 FPS||Great|
|H&N Field Target Trophy Green (10.03 Grain)||23.39 FPE||1024.70 FPS||Poor|
|Gamo Raptor Platinum (9.7 Grain)||23.38||1041.83 FPS||Great|
Therefore, if you’re planning to get Benjamin Marauder Synthetic Stock, you simply don’t have to worry about the velocity or accuracy.
Owing to its excellent FPE and FPS, it is ideal for hunting squirrels, woodchucks, chipmunks, and groundhogs.
Moving on to the repeater mechanism, Benjamin Marauder doesn’t disappoint here either.
You can easily fire up to 10 successive shots using your Marauder rifle.
This way, no pest can escape easily!
I have found that a lot of people admire this rifle for its ultra-quiet sound of 74 decibels .
Most users say that it’s so dead silent that if you’re shooting one squirrel, the others won’t even know.
When it comes to rifle architecture, the Benjamin Marauder weighs around 7.3 lbs.
Thus, it’s light enough to carry while you’re hunting pests.
The only major limitations to this rifle are its somewhat basic finish and consistency.
As you can see in the table above, the muzzle velocity deviates a lot as per the pellets.
Overall, the Benjamin Marauder makes for an accurate, quick, and noise-free PCP air rifle for pest control.
2. Diana Chaser – Best Air Rifle for Rats
If you’re looking for a budget air rifle for pest control, especially rats, Diana Chaser is worth trying.
This cheap air rifle for pest control is specifically amazing for rats as it’s available in both .177 and .22 caliber with varying muzzle velocity.
I suggest opting for the .177 version as it can work accurately with long distances.
As rats are small pests, you wouldn’t require a lot of power either but you do need great accuracy.
Moreover, Diana Chaser is also the best .177 air rifle for pest control as per several users.
Both the .177 and .22 Diana Chaser offer just the right velocity (FPS) and accuracy.
As mentioned above, you require around 500 FPS for hunting rats easily.
Thankfully, Diana Chaser offers 525 FPS (.177) and 460 FPS (.22) that work perfectly.
The table below also displays the various muzzle velocities (FPS) as per the pellets for .22 Diana Chaser.
|Pellet||Energy (FPE)||Muzzle Velocity (FPS)|
|RWS Meisterkugeln (14 Grain)||8.6 FPE||526 FPS|
|H&N Sport (13.73 Grain)||8.5 FPE||528 FPS|
|RWS Hobby Sport Line (11.9 Grain)||5.81 FPE||469 FPS|
|Sig Sauer Crux Ballistic Alloy (10.3 Grain)||6.7 FPE||541 FPS|
This rifle takes into consideration the amateurs and the professionals.
Hence, it is the best-value air rifle for pest control for almost everyone.
With a muzzle velocity of 525 FPS and energy of 8.6 FPE, you can either hunt small animals or practice target shots.
Moreover, it is inexpensive, so if you are a beginner looking for good air rifles, then this is the best option for you.
It also comes with a repeater mechanism and you can easily shoot 50 shots per CO2 fill.
Unfortunately, the grip of Diana Chaser is a little bit off.
The rifle is ambidextrous, so while versatile, it’s not the most comfortable.
3. Benjamin Marauder Air Pistol Prod: Best Air Rifle for Possums and Gophers
If you want to invest more but with less price, you can go for the Benjamin Marauder Air Pistol.
This is perfect for hunting possums and gophers since it requires a velocity of 800 FPS and Benjamin Marauder provides the same.
Moreover, this lightweight air pistol offers you excellent accuracy and if you are a good hunter, then you will definitely hit the right spot.
With a .22 caliber air pistol and 8 shots magazine, you can easily control the possum situation at your place.
Moreover, Benjamin Marauder offers an ultra-quiet experience in comparison to the pistol.
It gets the job done with 98 decibels.
The 3000 PSI of compressed air helps to have a rather amazing hunting experience in terms of sound.
Additionally, it only gives about 30 shots before the consistency starts to drop.
It is also very heavy, so it’s difficult to hand pump it.
Benjamin Marauder produces the best muzzle velocity and energy on the list. Plus, its trigger is lightweight and it has no recoil too.
|Pellet||Energy (FPE)||Velocity (FPS)||Accuracy|
|Beeman Kodiak (21.14 Grain)||32.35 FPE||830 FPS||Great|
|RWS Hobby(11.9 Grain)||25.4 FPE||980.30 FPS||Great|
|RWS Superdome(14.5 Grain)||28.64 FPE||943 FPS||Mediocre|
|JSB Exact Domes (15.9 Grain)||25.1 FPE||843 FPS||Mediocre|
|Gamo Raptor Platinum (9.7 Grain)||47.31 FPE||1041.83 FPS||Good|
|JSB Jumbo Exact (14.35 Grain)||28.26 FPE||941.61 FPS||Best|
|H&N Baracuda Match (21.14 Grain)||33.43 FPE||843.85 FPS||Good|
There is no doubt that Beeman Kodiak and JSB Jumbo Exact are the pellets that you can use for the Benjamin Marauder Air Pistol.
It’s quiet enough and has enough power to kill the possum in the first go.
Benjamin Marauder is the rifle of your dreams but it does not have a good finish.
In terms of its appearance as well, it is below average.
But when you’re getting such a great deal at the best price, then such details are minor.
4. Beeman R9: Best Air Rifle for Raccoons and Skunks
With a maximum velocity of 935 FPS, the Beeman R9 is your best bet at killing raccoons and skunks.
It is a dream to work with this rifle especially during hunting because of its spot-on accuracy.
Although .177 is the optimum caliber, if you are into eliminating the pest problem, then you can easily work well with .22 caliber too.
Beeman R9 is a vintage model but it can easily take over any air rifle of this velocity.
At 7.3 lbs, this German-quality air rifle will not disappoint you even if you want to target practice.
Unfortunately, the only issue with this rifle is with the adjustment screws that loosen up after some time.
You’ll have to tighten them up just in case before you start practicing or hunting.
Additionally, it does not have a silencer, so it will get a bit difficult to fire a shot and not wake the neighborhood.
With its sheer consistency, accuracy, and appearance, you will not be able to part with this rifle.
It eases in your hands naturally and comfortably.
|Pellet||Energy (FPE)||Muzzle Velocity||Accuracy|
|RWS Hobby (7.0 Grain)||12.77 FPE||906.39 FPS||Good|
|H&N Field Target Trophy Green (5.56 Grain)||13.68 FPE||1052.39 FPS||Excellent|
|Crosman Premier (7.9 Grain)||13.87 FPE||889.19 FPS||Great|
|JSB Exact Diabolo (8.44 Grain)||13.85 FPE||859.59 FPS||Excellent|
|H&N Field Target Trophy (8.64 Grain)||14.10 FPE||857.15 FPS||Best|
|Gamo Raptor Platinum (4.7 Grain)||12.62 FPE||1099.35 FPS||Excellent|
|H&N Baracuda Match (10.65 Grain)||13.10 FPE||744.13 FPS||Excellent|
With a muzzle velocity of 857.15 and energy of 14.09 ft/lbs, H&N Field Target Trophy is your best bet for hunting raccoons and skunks.
5. Umarex 850 M2 CO2: Best Air Rifle for Iguanas
If you are looking for a CO2-based air rifle then, Umarex 850 M2 is the best air rifle you can get.
You may think that with CO2 the cost of the air will increase, but this is not the case.
This air rifle is extremely affordable.
Additionally, it works well with a wide range of pellets and gives an accurate shot with most of the pellets.
If you are a beginner then this is the air rifle for you.
You can practice target shots or even get rid of the Iguana problem in your backyard.
With a 750 FPS and light trigger pull, this is a favorite among shooters.
However, the bolt of Umarex 850 is a bit rough, so if you are starting out, it may seem uncomfortable to you.
Additionally, if you want to hunt silently, this air rifle is a bit too noisy for you.
It is powered by 88g CO2, 8 shot magazine, and can easily shoot about 250 pellets before it runs out.
Moreover, it comes with an adjustable trigger and automatic safety that is good for a beginner.
But if you are a regular, then the automatic safety may irritate you a bit.
With a repeater mechanism, moderate sound, and a great finish, this is the best CO2 air rifle that you can get to hunt iguanas.
|Pellets||Energy (FPE)||Muzzle Velocity||Accuracy|
|H&N Baracuda Match (10.65 Grain)||10.02 FPE||651 FPS||Best|
|JSB Exact Diabolo (8.44 Grain)||9.26 FPE||703 FPS||Excellent|
|RWS Hobby (7 Grain)||7.99 FPE||717 FPS||Great|
|Gamo Raptor Platinum (4.7 Grain)||6.51 FPE||790 FPS||Great|
|Crosman Premier (7.9 Grain)||8.48 FPE||695 FPS||Excellent|
|H&N Field Target Trophy (8.64 Grain)||9.38 FPE||699 FPS||Great|
|H&N Field Target Trophy Green(5.56 Grain)||6.35 FPE||717 FPS||Great|
It may seem as if the 651 FPS is low to hunt an iguana but the average muzzle energy of 10.02 ft/lbs is great for the kill.
As you can observe, Umarex 850 M2 compliments a wide range of pellets, so you can go for any of the above to get the best shot.
6. Seneca Dragon Claw 500cc: Best Air Rifle for Coyotes
Seneca Dragon Claw has been consistently getting the best air rifle seller award since 2011.
With a 679 FPS of muzzle velocity, it uses a .50 caliber and releases 230 ft/lbs muzzle energy.
This makes it a perfect rifle for pests such as coyotes, feral hogs, foxes, and possums.
This rifle is literally considered the ultimate survival hunting rifle.
Additionally, it comes with dual air chambers, a total of 500cc with a 3000 psi pressure.
Unfortunately, it has no repeater mechanism, so you’ll have to load it time and again.
On the other hand, you can shoot more than 20 shots before you’ll have to fill the air again.
Additionally, its trigger is a bit rough and there is a lot of resistance from the trigger before firing.
I would advise you to fill the tank with the scuba tank because this gun is heavy and it will get difficult to fill it manually.
It is accurate and when the pressure is good, the gun is consistent too but as the pressure drops, the consistency becomes shaky.
This rifle is loud and has a manual safety option instead of automatic.
7. Diana Stormrider: Budget Air Rifle for Pest Control
If you are looking for a quality rifle on a budget to control the pest problem at your home, then look no further.
Diana Stormrider is an absolute favorite among the shooters for its performance and accuracy.
Moreover, this air rifle is one of the best budget options available in the market.
One of the best features of Diana Stormrider is its red-colored warning feature when you are about to pull the trigger.
The safety light comes on to warn you once.
However, its bolt handle is not easy to operate.
The forward action is comfortable but when you pull it back, its small size makes it difficult to grasp.
Plus, its consistency drops after 20 shots due to the lack of PCP level.
So you have to refill it up to 2900 psi to get the desired results.
Another great feature of Diana Stormrider is the noise level which is way better than the other rifles.
It produces very little sound and you can easily use it for accurate shots.
The low noise level is also beneficial for pest control as you can kill one without alarming the other.
Diana Stormrider offers you a whopping 1050 FPS of muzzle velocity.
This means that you can get away with any kind of pest situation at home.
Not only will you injure an animal but you will also most likely kill them.
The table below displays the FPS with different bullet types.
|Pellets||Energy (FPE)||Muzzle Velocity||Accuracy|
|Gamo Raptor Platinum (4.7 Grain)||11.93 FPE||1068.83 FPS||Poor|
|H&N Baracuda Match (10.65 Grain)||18.59 FPE||886.44 FPS||Great|
|JSB Exact Diabolo (8.44 Grain)||16.09 FPE||926.58 FPS||Excellent|
|H&N Field Target Trophy Green (5.56 Grain)||13.27 FPE||1036.61 FPS||Good|
|Crosman Premier HP (7.9 Grain)||16.1 FPE||957.78 FPS||Poor|
|H&N Field Target Trophy (8.64 Grain)||16.91 FPE||938.79 FPS||Best|
|RWS Hobby(7.0 Grain)||14.85 FPE||977.23 FPS||Good|
The H&N Field Target Trophy came out the best out of the lot due to its muzzle energy being 16.9 ft/lbs which is the optimum energy that you require.
With Gamo Raptor Platinum, the velocity was the highest but its performance was poor due to its low energy of 11.92 ft/lbs.
8. Diana RWS 34: Best Spring Piston Air Rifle for Pest Control
The upgraded Diana 34 version is so good that shooters are raving about this.
It is almost the perfect spring-piston air rifle one can own.
It has the lightest trigger pull and will not recoil and hurt you in any way.
Diana RWS 34 also includes an automatic safety that is comfortable and easy to use for both left and right-handed shooters.
With a 1000 FPS muzzle velocity, its consistency levels did not drop or disappoint.
Simultaneously, the accuracy of the piston was also pretty great.
It’s interesting to note that pellets heavier than 7.9 grain performed better than the others.
|Pellets||Energy (FPE)||Muzzle Velocity||Accuracy|
|GTO Predator(5.5 Grain)||16.45 FPE||1160.29||Great|
|RWS Hobby (7.0 Grain)||14.67 FPE||971.47||Poor|
|Crosman Premier HP (7.9 Grain)||15.22 FPE||931.39||Great|
|JSB Exact Diabolo (8.44 Grain)||15.20 FPE||900.51||Excellent|
|H&N Baracuda Match (10.65 Grain)||13.96 FPE||768.35||Best|
|H&N Field Target Trophy (8.64 Grain)||15.3 FPE||892.84||Excellent|
|H&N Field Target Trophy Green (5.56 Grain)||15.73 FPE||1128.73 FPS||Great|
As we can see from the above table, the best results were produced by the pellets above 7.9 grain.
Although the 5.5 grain also produced good results.
But if you want to hunt well and want consistent and accurate shots, then definitely go for a good grain value.
Unfortunately, it does not have a repeater mechanism and is only a single-shot rifle, so you will have to reload after every shot.
Additionally, it has an average noise level but that goes for all the spring pistons.
However, with that good muzzle velocity and a great combination of pellets, you can get rid of the pest problem at your home in no time.
Diana 34 does not have the appearance of a modern air rifle.
So if you are vintage at heart, then its appearance will appeal to you, otherwise, you may find it average.
But don’t go for the looks since its performance exceeds your expectations.
9. Airforce Texan: Most Accurate Rifle for Long Range Pest Control
If you are looking for the world’s most powerful long-range air rifle, then your search stops right here.
The Airforce Texan is the best long-range rifle that you can use.
With the muzzle velocity of up to 1000 FPS and strong FPE, you are no longer limited to small games of hunting nearby pests.
Rather you can indulge in medium or long-range shots and in big games. It’s even easy to score a deer with the Airforce Texan .457.
|Pellets||Energy (FPE)||Muzzle Velocity||Accuracy|
|JSB Exacts Diabolo (44.75 Grain)||74.37 FPE||865 FPS||Great|
|Crossman Premiers (19.0 Grain)||34.03 FPE||898 FPS||Good|
|Predator Polymag(44.75 Grain)||70.13 FPE||840 FPS||Excellent|
|Beeman Kodiak (21.14 Grain)||29.38 FPE||791 FPS||Great|
You may also check our individual Airforce Texan review for an in-depth idea about the FPS and other features.
Of course with the world’s best product comes the high price range, so this air rifle is the most expensive one on this list.
It’s available in a variety of caliber options such as .357, .308, .257, and .510.
All these produce excellent results.
Unfortunately, the only problem is with the single-shot as it does not have a repeater mechanism.
Additionally, this air rifle is not for the faint-hearted, meaning that it is super loud.
But what else can you expect from a big bore rifle?
I personally love how I can change the caliber of the barrel according to the task at hand.
You can even hunt at night with the night vision scope and flashlight.
It also includes an in-built manometer that keeps a track of the pressure level in the barrel.
So, if you find your performance deteriorating, that means the pressure levels are dropping.
Hence, it’s obvious to state that it is a PCP that needs compressed air pressure.
Therefore, you need an external source to fill it.
With a 490cc tank, you can shoot about 50 consistent shots before refilling the tank.
It’s safe to say that this is not for the amateurs but only for the professionals.
It can produce over 500-foot-pounds of power and technically it blurs the line between a powerful firearm and an air rifle.
This last point is probably the best for the shooters since Airforce Texan is a low-maintenance rifle.
Occasionally, you can clean it up otherwise, you can keep it aside and it won’t bother you for a clean-up.
10. Hatsan AT44-10 QES: Quiet Air Rifle for Pest Control
Hatsan AT44-10 QES offers you the maximum muzzle velocity of all in the list.
It is available in various calibers such as .177, .22. And .25.
So, all of them have varying velocities ranging from 1000 FPS to 1350 FPS.
As the heading gives away, this rifle is known for its sound suppression system.
With a 64 decibel record, this is probably the quietest air rifle you will know.
Hatsan is very picky with its pellets, therefore, only a few pellets and grain size work well with it.
But as far as accuracy and consistency are concerned, you can rely on this air rifle for the best shot.
Additionally, it has a repeater mechanism with a 10 shot and a 9 shot rotary magazine.
This one also has an in-built manometer, automatic safety, and texture surface for easy grip.
You can also adjust the butt of the rifle according to your angle and eyesight.
This will provide a huge relief to the eyes.
It also comes with a removable air reservoir, so refueling while hunting is great for you.
It has a 180cc air detachable air cylinder and you can order the extras from their site anytime.
You can use Hatsan to hunt small or medium games but with 1000 FPS, you are sure to remove the pest problem from your backyard.
The energy produced is amazing and you are sure to kill the pests.
|Pellets||Energy (FPE)||Muzzle Velocity||Accuracy|
|RWS Superdome (14.5 Grain)||32.98 FPE||1012 FPS||Good|
|Predator Polymag (15.89 Grain)||29.94 FPE||921 FPS||Great|
|JSB Diabolo Exact Jumbo Heavy(18.13 Grain)||35.73 FPE||942 FPS||Best|
|H&N Baracuda Hunter Extreme (19.09 Grain)||33.81 FPE||893 FPS||Excellent|
The best feature of Hatsan is how smooth it is.
There is no vibration and no recoil, so you will have the best experience with this air rifle.
Moreover, Hatsan has an ambidextrous stock, so it is comfortable for both left and right-handed people — though it may not be too comfortable since it doesn’t specialize in either side.
With so many air rifles out there, it can be a bit confusing to keep up with all the information around.
But fear not! Just read the article according to the problem at hand.
Pests are sneaky little creatures that can destroy your backyard in no time.
When no other method works, turning to air rifles is the best option for you.
Frequently Asked Questions
Can You Use an Air Rifle in Your Background for Pest Control?
Yes, you can use an air rifle to hunt for pests in your backyard.
But you will have to check the gun laws of your area before doing so.
In a lot of countries and cities, there are very strict laws regarding air rifles and their usage.
Additionally, you should be 18 above to use air rifles.
Do check on your towns’ laws and regulations before you use an air rifle.
How Much Air Rifle Power Is Needed for Pest Control?
This completely varies according to the pest situation.
However, one important factor to keep in mind is the FPE, also known as muzzle energy.
The muzzle energy is dependent mainly on FPS and the pellet weight.
Typically, you require an air rifle with 1000 FPS for pest control.
But, you also need to know how much energy is required to kill each pest in one clean shot.
You can also refer to the table above to get a better idea about the FPE required for each type of pest.
Do Chipmunks Bite?
Chipmunks are definitely not friendly as they are a house of deadly diseases.
But they bite in rare conditions such as when they are provoked unnecessarily.
Otherwise, they’ll probably run away if they sense the slightest danger.
Do Chipmunks Carry Rabies? What Disease Do Chipmunks Carry?
Small pests such as chipmunks have a relatively low chance of spreading rabies.
It’s almost equivalent to zero.
But chipmunks do carry diseases like plague, hantavirus, and salmonella which are harmful to both babies and adults.
How Can You Kill a Rat in a Humane Way?
Using an air rifle is the most humane way to kill a rat since the rat will die in a second.
Rat poison and rat traps are more cruel methods.
Which Animal Is More Dangerous, Possums or Raccoons?
Possums are docile animals who try to avoid confrontation as much as possible.
But if cornered or provoked, they can attack.
On the other hand, raccoons are aggressive creatures and would defend themselves in the first go.
They would try to bite you or attack you, sometimes even viciously.
Will a BB Gun Kill a Raccoon?
No, a BB gun will not kill a raccoon because it does not produce the kind of energy required to kill a raccoon.
It will only injure the raccoon which is inhumane as it will die a slow death.
Or it can become too aggressive and attack you.
Are Iguanas Poisonous?
Iguanas produce a venom that is generally harmless but they do have sharp teeth.
Although there have been a few cases where iguanas have bitten humans, this is rare.
Their bites can give serious injuries to your face, ankles, fingers, etc.
Do Iguanas Change Colors? What Causes an Iguana To Change Colors?
Iguanas often change colors but not like chameleons.
They turn orange during mating season and dark green as they age.
In low temperatures, they turn black or brown to absorb heat and in hot temperatures, they turn to pastel colors.
Is it legal to shoot a skunk with a pellet gun?
As we mentioned before, shooting any kind of pest has to be mandated by law.
If your district or towns’ law states that you can shoot any pest with a pellet gun or air rifle, then you can do so. In a lot of places, it is legal to shoot pests like skunks in your backyard.
Can a .22 Kill a Coyote? What Size Air Rifle Can Kill a Coyote?
No, a .22 rifle will hardly injure the coyote, so will a .177.
They will either just run off in a distance or towards you for hurting them.
You can go for a .25 air rifle which will impact them more.
With a good distance and muzzle energy, a .25 will definitely work for you.
How Many Times Can a Skunk Spray? Is Skunk Spray Toxic?
Skunks spray only in dire circumstances like when they feel threatened.
They can spray 6 times in succession.
Skunk spray is toxic for both dogs and humans, for the former it may cause diarrhea and vomit but for the latter, it will cause irritation.
