Ants might be small and seemingly low damage pests as they are definitely not as harmful to your chicken coop as mites, lice, and rats. You might probably think that because birds (chicken) eat insects, they will take care of the problem themself. 

But the truth is, even though in theory chickens eat ants, they might not want to eat them if they are well-fed in general. And depending on the type of ants, this seemingly mild pest infestation could turn out to be a real danger, especially if they start to come in larger numbers.

Why Are There Ants In My Chicken Coop? 

Ants are natural scavengers and they are always looking for food and water so the chicken coop is a place where they should be able to find everything they need. They might be attracted to the food that is left uneaten by the chickens. If there are broken eggs in the coop, they can also be the reason why ants are being attracted. 

As chickens are quite susceptible to diseases and infections, it is very important to keep the chicken coop clean, neat, and tidy. Always remove any uneaten food, broken eggs, or dead chickens as all of this can quickly attract the ants.

Ants In Chicken Coop

In general, ants are not dangerous for chickens. If they are not in large numbers, they are more of a nuisance. But a colony left unattended can quickly grow in size and become quite a challenge to deal with. 

Some types of ants such as fire ants attack and sting when disturbed and can turn out to be a serious issue. Fire ants can be a problem especially for younger chickens and smaller breeds, as the venom from their sting is painful and can lead to a secondary infection. And if there are a lot of fire ants attacking a chicken, the swelling and neurosis caused by stings can even kill the bird. 

Fire ants are a threat to mother hens as well. Stinging from ants can cause them to feel so uncomfortable that they will leave the nest and abandon the eggs. If you have a case of fire ants in your chicken coop, make sure to eliminate the ant colony completely so they do not pose a threat to the chickens.

Fire ants originally come from South America but today are widely spread in the Southern United States. You will recognize them fairly easily as they are red or reddish in color and have a stinger. 

Fire ants are famous for being invasive and aggressive. They will attack if they get disturbed. Fire ants sting and they do not actually bite, and their stings can cause unbearable pain for both humans and chickens. 

When fire ants attack, they release a venom that causes swelling, severe pain, and localized neurosis. Depending on the number of ants, the venom from the stinging can actually kill a smaller or younger chicken or lead to a secondary infection. 

Fire ants build large mounds that can reach up to 2 feet in width and 18 inches in height, with numerous tunnels inside. If left unattended, a fire ants colony can quickly grow in size. Fire ants make their mounds in all sorts of soil, mostly in sunny places, so it is not uncommon to find their mound near the chicken coop. 

If you see fire ants attacking your chickens, brush them off as carefully as possible to avoid them stinging even more viciously.  

Although chickens occasionally will eat fire ants, if there are too many of them, they might pose a significant threat. In the case of fire ants in the chicken coop, you need to take the appropriate measures to destroy the colony so that it doesn’t grow in size and become a serious hazard to your chickens. 

Carpenter Ants In Chicken Coop

Carpenter ants are generally bigger than most ants and are dark brown or black in color. They chew tunnels in rotten or decaying wood. You can easily spot a carpenter ants infestation due to the piles of sawdust material they leave behind. 

Carpenter ants are not dangerous for chickens. Actually, as they are bigger in size than normal ants and can provide a tasty treat. The problem is that if there are carpenter ants in the chicken coop, their nest is probably nearby. 

Up to 50 000 carpenter ant workers can live in a single colony so timely measures are important to prevent them from developing. Carpenter ants need moist environments for their eggs to survive and they will take advantage of any old, damaged, or rotten wood or tree in your house, garden, or farm. 

In case you spot carpenter ants in the chicken coop, you need to locate the nest and eliminate the colony in order to prevent further damage to wooden structures or trees. 

Other Types Of Ants in Chicken Coop I Black Garden Ants

Black garden ants are the most common type of ants you will find around your house and garden, so why not in the chicken coop as well? 

They are small in size, black in color, and are attracted to all kinds of food, garbage, or even feces. So they are probably venturing into the chicken coop in search of food and if they find any, they will leave a scent trail for the other ants to follow. In a short period, the chicken coop might become infested with black garden ants. 

Even though they do not pose danger to chickens, these ants are often carriers of bacteria and diseases such as salmonella and if the birds decide to eat them, some problems like infections might arise.
