Spider Control in Markham

Markham has two pest realities separated by about 30 years of construction. Walk down Main Street Unionville and the heritage homes there have fieldstone foundations with gaps that mice have been using since before the town had a traffic light. Drive 15 minutes north to Cornell or Box Grove and the brand-new detached homes are already getting mice through settling gaps around gas lines and dryer vents — the foundation shifts in the first two winters and opens up entry points the builder never sealed. The Rouge River cuts through eastern Markham and delivers raccoons, skunks, and squirrels right into the backyards along Rouge River Estates. Milliken is rat territory — the dense mix of restaurants and food businesses along Steeles and McCowan feeds Norway rat populations that burrow under adjacent residential foundations. Angus Glen looks pristine, but the golf course is raccoon habitat and they do not stay on the fairways.

Signs You Need Spider Control in Markham

• Persistent spider webs in corners of ceilings, basements, garages, and window frames despite regular cleaning
• Live spiders visible during the day — most house spiders are nocturnal and hide during daylight hours
• Small brown spiders with violin-shaped markings on their backs — potential brown recluse (rare in GTA but worth monitoring)
• Multiple small spiders appearing in sinks, bathtubs, or basement floor drains at once
• An unusual number of flying insects in the home — if you have insects, spiders will follow
• Large wolf spiders indoors in fall when they seek shelter from cooling temperatures
