What Is Bb Gun?

A Bb gun is a type of air gun made to fire metallic spherical projectiles known as BBs, similar in size to lead birdshots used in shotguns. Modern BB guns use round pallets or steel balls known as bullet balls.

The new guns have a smooth barrel of 4.5mm, and the diameter of the bullet ball is 4.3 or 4.4 mm. The balls are made of zinc or copper to prevent erosion. Some manufacturer still makes lead balls.

BB gun has three essential components: a bullet ball chamber, a tube for projectile direction, and a frame and system to release the propellent at an appropriate speed. Pulling the trigger of the BB gun causes the sear spring to lift from the piston by pushing on it.

When the piston releases from its latch, the spring will open up and push it forward. The air in the chamber behind the bullet ball compresses swiftly, creating the pressure to thrust it down the barrel.

 Will A Bb Gun Kill Squirrels?

BB gun will cause a slow and painful death. It cannot kill the squirrel instantly due to the reduced power impact by the bullet and comparatively lower caliber than the other guns that can kill squirrels instantly. A standard high-power BB gun has a .177 caliber and can shoot BBs at 490 fps.

The impact of the BB gun bullet is low and will only cause a few fractures and wounds that can cause slow deaths in the squirrels ranging from a few hours to days. Therefore, your state might not include BB guns as hunting guns, and it might be illegal to use them to kill squirrels and other animals.

Dealing with the squirrel is complicated. There are many ways to repel the squirrel because killing them is inhumane and can be illegal depending upon your state. BB guns fire small bullet balls that are not powerful enough to kill squirrels instantly.

Squirrels are fast and move quickly, so you will not be able to kill them immediately with your shot. The bullet ball can only injure the squirrel leading to a cruel and painful death.

There are three types of squirrels; ground squirrels, tree squirrels, and flying squirrels. In some states, you will have to get a permit from the government to kill the squirrels.

Killing a squirrel on your property is legal in many places, only in hunting season and when you do not live close to the city. You will have to take an official permit for the off-season killing of squirrels, even on your private property.

How Much Fps Is Required To Kill a Squirrel?

The FPS required to kill squirrels depends upon the caliber of the gun and your target. It is better to aim for a headshot of the upper chest cavity of the squirrels.

The bullet must pass through the fur and bones to damage an organ to kill the squirrel. The bullet will cause shoulder blade and rib cage fractures even with a low impact.

However, the headshot is challenging as squirrels are quick, and the bullet does not penetrate the head bones.

To kill a squirrel, select at least 177 caliber guns that fire bullets at a high velocity of at least 800fps. The speed and impact of the bullet must be strong enough to penetrate the squirrel’s body and kill it immediately. The guns with lower fps will only injure the squirrel. Therefore, BB guns are not ideal for hunting squirrels.

What Is The Best Caliber Bb Gun for Killing Squirrels?

Bigger guns do not mean better guns. The best guns shot bullets quickly and hit the target with the highest power. When purchasing a gun for hunting, it is necessary to keep the caliber of the gun and the speed of the bullet in mind.

The .22 and .177 caliber guns are best for killing squirrels. The .177 caliber BB guns work best at the velocity of 800 fps is lower and gets to the target twenty-five percent and thirty-three percent faster than the .22 caliber gun.

The .22 caliber gun is the best and clears away the target instantly. It is deadly, quiet, and accurate compared to the .177 bb guns. The .22 caliber gun is also a perfect choice for killing the target from longer ranges like thirty-five to forty meters. Therefore, making it ideal for killing the squirrels sitting on the branch.

What Are the Best Bb Guns You Can Use to Shoot Squirrels?

Before purchasing a gun, it is necessary to go through all the guidelines given by the local authority so you can later stay out of trouble and many other issues. Remember, many states allow shooting only during specific months. It is necessary to get a permit for off-season shooting. While purchasing a BB gun, look out for its length and weight and purchase safety equipment with the BB gun.

After a detailed search, I found a few BB guns with good reviews that are comfortably available.

What Can You Hunt With A BB Gun?

It is impossible to kill any animal instantly with a BB gun as it does not have enough power to penetrate the body. However, it will cause bruises, wounds, and fractures.

To humanely kill small animals, like squirrels and rabbits, it is better to use a gun with more power and high velocity, which can take down the target within one shot and cause less to no pain to the animal.

BB guns are better for practicing your target with cans for hunting. Never attempt it on humans or other animals as it can cause severe injuries and damage the retina if it hits the eye.

How To Get Rid Of Squirrels Without Using BB Guns?

Squirrels are the most annoying and destructive animals in the yard. They will burrow in the grass to store food and can eat fruits and vegetables grown in your house plants. Squirrels enjoy eating the bulbs and can dig deep in the roots to search for them, thus weakening the plant.

Even though squirrels are annoying, they are cute innocent creatures. Many of us will agree that it is inhumane to use BB guns to kill the squirrels as the bullet balls will cause severe injury and pain to the poor creature.

Therefore, you can use other methods to get rid of squirrels. Following are a few tips to remove squirrels from the yard without hurting them.

  • It is better to prepare ahead than to deal with the problems of squirrel infestation later. Install a high fence around your yard. The fence must be at least three feet big with narrow mesh. You can also use electrical mesh, but it is risky when you have pets and children.
  • Keep the area around your house and yard clean. Remove garbage cans, trim the bushes, and clean fallen fruits and leaves daily to avoid squirrels’ attraction.
  • Plant the mint, garlic, rosemary, pepper, and lemon plants around your house. Squirrels have sensitive nostrils and hate the sharp and pungent smell. Squirrels also hate daffodils, fritillaries, geraniums, hyacinths, Galanthus, and lily-of-the-valley. Also, squirrels can die from eating daffodils as they contain poisonous compounds.
  • Dogs are the natural predators of a squirrel. Even though it is difficult for dogs to catch a squirrel, a pet dog can intimidate the squirrels in your yard and scare them away for good.
  • Remove all the standing water sources like bird water bowls and water fountains. Cover the pools when not in use. Fresh and clean water will attract rats to live near your house.

Essential oils also work effectively in removing squirrels. Soak a few cotton balls in mint or cinnamon oil and place them inside your potted plant.

Chemical squirrel repellents you can find at your home are dryer sheets, mothballs, vinegar, and ammonia. All of these are great for scaring squirrels.


BB guns can and cannot kill squirrels. It depends upon your target, the gun’s caliber, and the power at which the bullet hits. After detailed research, I can conclude that BB guns are not strong enough to kill squirrels in one shot.

Instead, it causes slow and painful death which is inhumane. The killing of squirrels is legal in many states, and you can kill the squirrels on your property with an appropriate hunting gun only during hunting season. Hunting off-season will require a permit from the government.

Some states do not consider BB guns as hunting guns. Therefore, do detailed research according to the laws of your state before picking up a weapon to kill animals. You can use other methods mentioned above to remove them instead of killing them.


Whether it’s illegal to shoot squirrels in your backyard depends on where you live. Some places may allow it, but others don’t because of laws protecting wildlife. It’s really important to look at your local and state laws or talk to a lawyer before you do anything.

The strength of a BB gun you’d need to humanely take down a squirrel is usually about 12 foot-pounds of energy (FPE). But being accurate is key. Aim for the squirrel’s head to make sure you kill it quickly and kindly without causing it to suffer.

For hunting squirrels, a .22 caliber rifle is often the best choice. It’s a good mix of accurate and powerful enough for small animals. If you know how to use it well, it can ensure a clean, kind kill. However, being good at this and knowing about animal bodies is important if you want to do this responsibly and ethically.

Yes, a 4.5mm BB could kill a squirrel. But for a fast, kind kill, you must aim your shot well. Usually, shooting for the head works best. Remember, what you do needs to follow local wildlife laws and kind hunting rules.

Although a CO2 pistol could seriously hurt a squirrel, it’s not the best option. These pistols usually don’t have as much power and accuracy as air rifles. So, you might end up hurting the animal instead of killing it quickly, causing it to suffer needlessly.

Squirrels can be hard to shoot because they’re small and move quickly. This needs good shooting skills and patience. Always remember your duty to kill cleanly and quickly to avoid causing unnecessary pain and suffering.
