Ask Us Anything
Why do ants enter Ontario homes?
Ants may come indoors while searching for food, water, or shelter. Small openings around doors, windows, pipes, and foundations can provide entry.
Depending on the species, nests may be found in soil, under stones, within landscaping, in pavement cracks, or in damp wood and structural voids.
A visible trail often shows a route between a food or water source and a nest. Following the trail can help identify entry points and areas of activity.
Carpenter ants are larger than many household ants and may nest in damp or decaying wood. They do not eat wood, but their nesting can damage it over time.
Store food in sealed containers, clean spills, address moisture, and seal accessible gaps around doors and utility openings.
Technicians inspect activity, identify likely trails and entry points, and tailor treatment to the ant species and conditions found at the property.
