Ants, Spiders, and Rodents Are Common Problems in Ontario
Homes throughout Ontario regularly deal with pest activity during the year. Ants often appear along kitchen counters, sinks, and baseboards, and what seems like a small trail can quickly lead to a much larger colony hidden nearby. Spider webs frequently return in garages, corners, and outdoor areas as insect activity increases.
Rodents create even greater concern for homeowners. Scratching sounds in the attic, droppings in cabinets, and gnaw marks along walls can all be signs that rats or mice are already inside the home. If left untreated, rodents can contaminate living areas and cause damage to insulation, wiring, and stored belongings.
Without professional pest control and prevention, these issues rarely disappear on their own and often continue to return.
