Odorous Ants
Odorous house ants are small ants about 2.5 millimeters long and dark brown in color. They are found throughout Ontario. Their name comes from the disagreeable rotten odor that is given off when the worker ants are crushed.
Odorous house ants commonly nest outdoors in the soil under stones, logs, mulch, debris and other items. They will however also nest indoors in wall and floor voids, particularly in moist or warm areas. If you are noticing worker ants entering your home, cottage or building it is an indication that they are nesting outdoors and entering the house in search of food. If winged swarmers are found indoors, or if workers are consistently seen in great abundance, it likely indicates they are nesting within the house.
Odorous house ants regularly forage for food along well traveled trails. They feed on dead insects, sweets, meats and kitchen crumbs. One of their favorite foods is the sweet honeydew produced by plant sap feeding insects such as aphids and mealy bugs.
Control of odorous house ants can begin with an attempt to locate the origin of the ants.
Odorous house ant colonies inside the house can be treated by a professional and may included a combination of spraying and baiting.
