Why Can't I Keep Ants Out Of My Ontario Home? 


February 15, 2021

California has about 270 species of ants. There are only a few ant species in Ontario that are indoor pests. These ants can be destructive and sometimes even dangerous, particularly if you have an allergy to their bites or cannot get away from them. They may form long lines of ants from the nest to the food they have found in your house. In addition, they protect aphids, mealybugs, and soft scales on your indoor plants because they eat the honeydew these insects excrete.

Preventing Ant Infestations

All of these ants are very hard to remove once they are in your home, so prevention is the best way to keep them out.

There are two ways to prevent ants from entering your home: exclusion and sanitation.  

  1. Exclusion: Ants can get in through tiny cracks in the foundation or walls of the house. They also like to enter along pipes and wires. Caulk all cracks and crevasses and around pipes and wires as they enter the home. Make sure that window screens and screen doors are tight and have no holes in them. Check the weatherstripping at the base of doors to make sure it is tight and doesn’t have gaps ants can use to enter the home. Caulk cracks and crevasses and around pipes and electrical wires inside the home as well. Make sure tree branches do not touch the house, or ants will use them as bridges.
  2. Sanitation: Make sure that foods that ants really like, such as honey, sugar, pet food, and similar foods, are stored in plastic or metal containers that have been washed to remove any residue from the outside of the container. Clean up grease and spills from the stove and elsewhere. Clean the backs of closets, behind and under heavy appliances, and other out-of-the-way places. Make sure all trash containers with food in them have tight-fitting lids. Empty trash daily. Wash out soda cans or bottles before putting them in the trash or recycling containers. Make sure that outdoor trash and recycling containers have tight-fitting lids and are set out for emptying whenever the trash company comes.
