Ants invade your home through tiny cracks in search of food, leaving behind a long lasting and invisible scent trail for the rest of the colony to follow. Do-it-yourself sprays just kill the ants you see and if you don't find the nest and eliminate the queen they are soon back on the trail. The most common types of ants include:
Tetramorium Caespitum
Monomorium Pharaonis
Omnivore; prefers sweets but also eats other insects.
