Call (613) 743-8074Search common structural pests found across Eastern Ontario, compare visible signs and learn when professional inspection may be appropriate.
Seasonal conditions can increase sightings, but activity varies by property.
Use the search and filters to narrow the list. Wildlife is not included.
Crawling insectsAnt activity can move from exterior nesting areas into kitchens, bathrooms, wall voids and other protected spaces. Identification helps determine the right control strategy.
Biting pestsBed bugs can spread through luggage, furniture, clothing and shared spaces. Early identification and a structured treatment plan can help limit spread.
Crawling insectsCockroaches often hide in warm, dark areas near food and moisture. Effective control targets harbourage while reducing food and water sources.
RodentsMice can enter through small openings and establish activity near food, storage and warm nesting sites. Long-term control includes finding how they are getting inside.
RodentsRat control requires careful inspection of travel routes, exterior harbourage, vents, utility areas, storage and food sources.
Stinging insectsWasp and hornet activity can occur around eaves, soffits, wall voids, sheds, decks and landscaping. Treatment depends on the nest location and species behaviour.
Flying insectsRecurring fly activity often points to a breeding or food source. Control works best when the source is identified rather than treating adult flies alone.
Occasional invadersSpider activity is often connected to insect prey, exterior lighting, webs and protected harbourage around the structure.
Occasional invadersEarwigs prefer damp, protected areas and may move indoors from mulch, vegetation, foundation edges and moisture-prone spaces.
Biting pestsFlea control requires attention to the insect lifecycle, pet resting areas and indoor harbourage because immature stages can remain in the environment.
