In Markham, wasp nests commonly show up on backyard structures and protected exterior edges, not just on rooflines. That pattern is common in places like Unionville, Cornell, and Markham Village, where the blend of established communities, newer compact residential areas, and preserved historic districts means older trim details, covered porches, detached backyard structures, and sheltered fence corners all create practical nesting spots.
Why the problem appears anywhere on the exterior
The combination of heritage-style streetscapes and newer suburban housing means nests can appear almost anywhere on the exterior envelope. In heritage areas, older trim and architectural details create more sheltered voids. In newer areas, builder gaps and modern soffit designs offer different attachment points.
How to spot an active nest
People often see wasps collecting under a porch roof, entering a shed gap, or building behind one protected fence post cap. Once that traffic starts repeating, the nest is usually active and should be dealt with before it expands.
