When an ant dies, it releases formic acid. This chemical can be toxic in high doses, but it’s also responsible for the ants’ distinct smell.

When an ant is killed, it releases a chemical that ants are attracted to. This smell encourages other ants to come to investigate the scene and collect the dead ant’s remains.

Why do dead ants smell like ink?

Dead ants smell like ink because of formic acid. This is an organic compound that is also used as a preservative in feed for livestock.

Ants use this smell to identify other members of their colony and also to ward off predators. The acid is synthesized in special glands on the ant’s abdomen and released when the ant dies.

What smell do ants hate?

There is a genetic component to the sensitivity to the smell of ants. Some people are more sensitive than others and can detect the smell from farther away. The smell comes from a compound that is released when an ant is killed.

Interestingly, this sensitivity to the smell of ants could be due to genetics. Researchers found that some people are more sensitive to the smell of formic acid—the compound that ants release when they are killed.

This discovery could assist researchers and scientists in better understanding why some people are more likely to get bitten by ants.
