Signs of Common Ontario Pests

Bed bug treatment is the most expensive and labour-intensive pest service in Ontario. Heat treatment — the gold standard — involves raising room temperatures to 50°C+ for several hours to kill all life stages including eggs. Chemical treatment is cheaper but typically requires 2–3 visits over 2–4 weeks to achieve full eradication. Most Ontario companies offer a 90-day retreatment guarantee for bed bug jobs. Always ask for this in writing. (Serving Markham, Ontario.)
