It's how ants follow one another. They drag their buggy bottoms on the ground, leaving a chemical trail that other ants can follow. That's how millions of ants can find the same piece of food or whatever. They can also send chemical signals along the trail such as "I found food!" or "I'm being attacked, send help!" and such.
Ordinary cleaners will not dispose of such trails, thus how the ants found their way back to your kitchen even after you cleaned. |
