Spider Season in Southern Ontario: Why House Washing and Pest Control Go Hand and Hand

If you've noticed spider webs covering your windows, soffits, porch lights, and front entrance, you're not alone. Every year, homeowners throughout Collingwood, Wasaga Beach, Blue Mountain, Thornbury, Meaford, Stayner, Owen Sound, and everyone across Southern Ontario experience the same thing as spider season reaches its peak.

The good news? There are effective ways to reduce the problem—and it starts with proper timing.

When Is Spider Season in Southern Ontario?

Spider activity begins increasing in late summer, but late August through September is when they're most active. During this time, mature spiders build larger webs and male spiders roam in search of mates, making webs seem to appear overnight.

For homeowners, this means:

• Spider webs around windows, doors, siding and soffit and inside your home.

• Spider droppings

Should You Wash Your House Before Pest Control?

The best approach is to wash your home first, then have it professionally treated by a local pest control company.

A professional soft wash removes:

• Spider Webs

• Egg Sacs

• Dirt and Dust

• Algae and Mildew

• Pollen and Organic Buildup

Once your home's exterior is clean and dry, a licensed pest control professional can apply a perimeter treatment to help reduce spider activity, and trust me it works.

If you spray first and wash afterward, you can remove much of the treatment before it has a chance to do its job. So coordinate this wisely.

Why Bayside Clean Recommends Professional Pest Control

Pest Control Application

Every house wash includes the removal of existing spider webs and egg sacs. However, one thing we always explain to our customers is that no exterior cleaning company can prevent spiders from rebuilding webs.

During peak season, spiders can begin rebuilding within hours. That's why we recommend contacting a trusted local pest control company if you're looking for longer-lasting results. A professional treatment can help reduce spider populations around your home, making it easier to keep your exterior cleaner between washes.

For the best results, schedule your house wash first, followed by your spider treatment within the next day or two. Washing first removes webs, egg sacs, pollen, dirt, and organic buildup, allowing the pest control treatment to be applied to a clean surface. Washing after a treatment can reduce its effectiveness by removing much of the protective barrier.

House Washing and Pest Control Are Better Together

Many homeowners think they need to choose one or the other, but the reality is they work best as a team. A washing restores the appearance of your home by removing years of dirt, algae, pollen, and spider webs.

Professional pest control helps reduce the spiders and insects that quickly return after cleaning.
