What to Expect During Spider Season in Manitoba

Spider activity around Manitoba homes tends to peak in late summer and early fall, as spiders reach full maturity and start looking for mates, and for many species, that means building webs in the most visible spots on your property. Porch lights, eaves, and doorways attract the flying insects spiders feed on, which in turn draws the spiders themselves.

Most spiders found around homes in the region are harmless and are actually helping control other insect populations. Still, thick webbing across entryways and windows makes a property feel neglected, and a few species can deliver a painful bite if disturbed.

Reducing outdoor lighting near entry points, clearing webs regularly before they re-establish, and sealing gaps around windows and siding all help reduce activity close to the house. Because spiders follow their food source, treating the insects they prey on is often just as important as treating the spiders directly.

An exterior perimeter treatment combined with interior spot treatment knocks down both populations together, keeping webs from reappearing within days the way DIY sprays often allow.
