How small are LFAs?

LFAs are very tiny, measuring only about 1/16 of an inch long. This small size makes them challenging to see without close inspection.

What happens if I get stung by LFAs?

Stings from LFAs are known for causing a sharp, burning sensation, followed by intense itching and often a red welt that can persist for several hours or days. While most reactions are localized, some individuals may experience more significant allergic responses.

Where are LFAs commonly found?

LFAs are highly adaptable and can be found in a wide variety of environments, including trees, plants, soil, leaf litter, and even inside homes. They often prefer shaded, moist areas. They can also be transported unknowingly through infested plants, soil, and agricultural products.

How can I check my property for LFAs?

A simple and effective way to check for LFAs is to use the “peanut butter bait stick” test. Spread a thin layer of peanut butter on a chopstick or popsicle stick and place it in shaded areas around your yard, especially near plants or potential entry points to your home. After about an hour, carefully check the sticks for tiny ants.

What should I do if I find LFAs on my property?

If you suspect you have found LFAs on your own property, you can get assistance in identification by carefully collecting some ants (as noted above.)
