Spider Control

Keep Spiders and Webs Off Your Home’s Exterior

Spiders are one of the most common insect issues around homes and buildings. While most Ontario spiders are harmless, they can quickly become a nuisance when they begin building webs across soffits, siding, windows, doors, and outdoor fixtures. These webs create an unkempt appearance, attract other insects, and often reappear just days after being cleaned.

At Mitchell’s Nuisance Wildlife Solutions, we offer targeted exterior sprays designed to reduce spider activity and prevent webs from returning. Our services are ideal for homeowners looking to maintain a cleaner, pest-free exterior throughout the warmer months.

Understand Spider Activity

Spiders are mostly outdoor pests, but they’ll take advantage of sheltered areas on and around buildings. Knowing when and where they’re most active helps us treat them effectively — and stop web buildup before it starts.

When Are Spiders Most Active?

  • Late spring through early fall (May to October)

  • Peak activity during humid summer months

  • Web building increases during warm, dry weather — especially on shaded sides of buildings

Where Spiders Commonly Appear:

  • Soffits, fascia, and rooflines

  • Window and door frames

  • Exterior lighting and outdoor fixtures

  • Deck railings, patio furniture, BBQs

  • Behind shutters and in corners of siding

  • Garages, sheds, and basement window wells

Our Spider Control Approach

We use a professional-grade, Health Canada–approved residual spray that targets spiders where they hide and prevents new web-building activity. Treatments are applied to key areas around your home’s exterior, including soffits, siding, light fixtures, and entry points. Our process is safe for pets and people once dry and leaves no strong odour or staining.

Each treatment includes:

  • Knockdown of visible webs before spraying

  • Thorough coverage of spider harbourage zones

  • Recommendations to reduce moisture and vegetation near the home

  • Optional seasonal spray plans for continued control
