Scarborough has the widest range of pest problems in the GTA, and it comes down to the housing mix. The apartment towers along Lawrence and McCowan have chronic cockroach and bed bug issues — these buildings share plumbing risers, garbage chutes, and wall voids between units, and pests travel through all of them. Drive ten minutes east to Agincourt or Woburn and it is a different story: mice in the foundation walls of 1960s bungalows, raccoons ripping through aluminum soffits, carpenter ants in the older split-levels with water damage around the bathroom windows. Highland Creek runs through the middle of the district like a wildlife highway, and the Rouge Valley on the eastern edge brings everything from raccoons and skunks to coyotes right up to the backyards in Malvern and West Hill.
Scarborough's pest landscape is the most varied in the entire GTA because no other district has this range of housing types crammed into one area. The 1950s bungalows in Birch Cliff have settling foundations and original mortar joints that mice have been exploiting for decades — you can find droppings in the same wall cavities year after year. The high-rise towers along Lawrence Avenue East and McCowan Road deal with German cockroaches that spread between units through the shared plumbing risers. Management treats one floor and the roaches just move two floors up until treatment stops.
Agincourt's detached homes sit on large lots with mature trees — great for families, also great for raccoons looking for attic access through aging roof vents. Woburn's postwar housing stock has the same aging infrastructure problems as the rest of Scarborough's older neighbourhoods, but it also sits near the Highland Creek ravine system, which funnels skunks and raccoons right into residential streets.
The Scarborough Bluffs create their own microclimate along the lakefront — higher moisture levels mean more carpenter ant activity in the homes above the bluffs in Guildwood. Rouge National Urban Park is beautiful, but it also supports one of the highest raccoon densities in the GTA, and those animals do not respect park boundaries. By October, every property backing onto the Rouge in Malvern and West Hill is dealing with something trying to get inside before winter.

Pest Seasons in Scarborough
Spring
Raccoon mothers start showing up in Agincourt and Woburn attics by mid-March. They target the older bungalows where aluminum soffits have loosened over 50+ winters. Carpenter ants emerge along Highland Creek — check for frass near bathroom windows and anywhere you have had water damage.
Summer
Wasp season hits hard in Scarborough. Paper wasps nest under the eaves of the older homes in Birch Cliff, and yellowjackets build ground nests in the larger yards in Guildwood. Bed bug calls spike in June–August as people move apartments, especially in the Lawrence and McCowan tower clusters.
Fall
October is mice season. The bungalows in Woburn and Agincourt get hit first — mice enter where the gas line meets the foundation, through cracked mortar joints, and under garage doors with worn seals. Wildlife from Rouge Park and Highland Creek pushes west into Malvern and West Hill looking for winter shelter.
Winter
Mice are in the walls by December across every housing type. The cockroach problems in the high-rises never stop — closed windows and heating create the warm, humid conditions German cockroaches thrive in. Bed bugs continue year-round in multi-unit buildings regardless of season.
