Ants that come inside are after food and water resources and you will usually see a long chain of them between their nest and your food source. They usually like sugar, syrup, honey, fruit juice, fats, and meat.

Managing ant problems

It's nearly impossible to totally get rid of ants or preventing them from re-appearing, as controlling ants means a combination of mechanical, cultural, sanitation, and often chemical control methods.

Ants are beneficial to your garden and they also help control other pests such as termites, fleas, and dead insects.
