Ants In Chicken Coop I FAQ 

Ants may seem like harmless pests in your chicken coop, especially compared to more harmful pests like mites, lice, and rats. However, even though chickens eat insects, they may not necessarily eat ants, especially if they are well-fed. Depending on the type of ants, an infestation could become a real danger, especially if they start to increase in numbers.

Why Are There Ants In My Chicken Coop?

Is It Dangerous To Have Ants In The Chicken Coop?

Ants In Chicken Coop

While ants are generally not dangerous for chickens, if left unchecked, they can become a challenge to deal with. Some types of ants, such as fire ants, can be a serious issue, as they attack and sting when disturbed.

The venom from their sting is painful and can lead to a secondary infection, particularly for younger chickens and smaller breeds. If a chicken is attacked by a large number of fire ants, the swelling and neurosis caused by stings can even result in death.

Fire ants can also be a threat to mother hens. Stings from ants can cause them to feel uncomfortable and abandon their nest and eggs. If you have a fire ant infestation in your chicken coop, it is important to eliminate the colony completely to ensure the safety of your chickens.

Types Of Ants That Invade Chicken Coops 

Types Of Ants That Invade Chicken Coops 

There are different types of ants that invade chicken coops. You need to determine the exact species to know how to deal with them and to understand the extent of the threat they pose to your chickens. 

Most commonly, you would find fire ants or carpenter ants, but there might be other types of ants in the chicken coop as well. 

Fire Ants In Chicken Coop

Fire Ants In Chicken Coop

Fire ants, originally from South America, have become a widespread and invasive species in the Southern United States. These ants are easily recognizable due to their red or reddish coloration and stingers.

When disturbed, they are known for their aggressive behavior and will attack by stinging, causing severe pain and swelling in both humans and chickens. The venom from their sting can cause localized neurosis and, in some cases, even lead to the death of smaller or younger chickens or secondary infections.

Fire ants build large mounds that can quickly grow in size, up to 2 feet in width and 18 inches in height, with multiple tunnels inside. These mounds are commonly found in sunny areas near chicken coops.

If fire ants are attacking your chickens, it is important to brush them off as carefully as possible to avoid further stinging. Although chickens may eat fire ants on occasion, a large infestation can pose a significant threat. In order to prevent the colony from growing and becoming a hazard to your chickens, appropriate measures should be taken to destroy the fire ant colony.

Carpenter Ants In Chicken Coop

Carpenter ants, on the other hand, are generally larger in size than most ants and are dark brown or black in color. They chew tunnels in rotten or decaying wood, leaving behind piles of sawdust that are easy to spot as a sign of infestation.

While carpenter ants are not dangerous to chickens and can even provide a tasty treat due to their size, their presence in the chicken coop is cause for concern, as their nest is likely nearby.

A single carpenter ant colony can have up to 50,000 workers, making timely measures important to prevent the infestation from growing. Carpenter ants require moist environments for their eggs to survive and will take advantage of any old, damaged, or rotten wood or tree in your house, garden, or farm.

If you spot carpenter ants in your chicken coop, it is important to locate and eliminate the nest to prevent further damage to wooden structures or trees.

Other Types Of Ants in Chicken Coop I Black Garden Ants

Black garden ants are a common sight around homes and gardens, and they can easily find their way into a chicken coop in search of food, including leftover chicken feed or feces. They are small, black, and can quickly establish a colony within the coop.

Although black garden ants are not known to be harmful to chickens directly, they are often carriers of bacteria and diseases, such as salmonella, which can cause health issues for the birds if ingested. It is important to control the ant population in the chicken coop to prevent the spread of diseases and to maintain a healthy living environment for the chickens.

Ant Control In Chicken Coop

There are several ways to get rid of ants in a chicken coop. You have to use the most appropriate one depending on the type of ants you are dealing with, or better yet, a combination of methods to ensure you eliminate the problem completely. 

Remember, ants are attracted to food so make sure that there is no excess food in the chicken coop. Remove any leftovers, broken eggs, or spillage on the floor, and keep the coop clean and tidy. 

Get rid of all items that can be used by ants for creating their colony for example wood logs, old hardware, bits, and pieces that do not belong to the chicken coop. Keep the surrounding area clean from the grass because that way you will be able to spot any ant trails and deal with them more effectively. 

In case your birds are free-ranged, only use treatments that are labeled safe to use or keep the chickens detained for at least 24 hours after applying the treatment. Due to the toxic nature of ant killers, never use strong liquid insecticides inside the coop. 

We will provide recommendations for both ant killers that you can use to kill the ant mounds and natural solutions you can use inside the coop without causing any harm to the chickens.
