Why Are There So Many Spiders Around My House This Summer?

Why Are There So Many Spiders Around My Home in Summer?

If you've noticed more spider webs around your deck, garage, or windows this summer, you're not imagining things. As temperatures rise across the Fraser Valley, spider activity naturally increases—but spiders are usually a symptom of another pest problem rather than the problem itself.

At Priority Pest Management, one of the most common questions we hear during the summer months is, "Why do I suddenly have so many spiders?"

The answer is simple: spiders go where the food is.

Why Spider Activity Increases During Summer

Summer provides the perfect conditions for both insects and spiders to thrive. As mosquito, fly, moth, and beetle populations increase, spiders quickly move into areas where food is plentiful.

Several factors contribute to increased spider activity during the warmer months:

  • Larger populations of flying insects.
  • Warm temperatures that speed up breeding cycles.
  • Outdoor lights that attract insects after dark.
  • Gardens, shrubs, and landscaping that provide ideal hiding places.

If you're seeing more webs around your home, there's a good chance your property is attracting the insects that spiders feed on.

Common Places You'll Find Spider Webs

Spiders prefer quiet, sheltered areas where insects regularly pass by. Around Fraser Valley homes, we commonly find webs in:

  • Garage ceilings and corners.
  • Exterior light fixtures.
  • Window frames and window wells.
  • Under decks and patios.
  • Porch ceilings.
  • Around soffits and roof overhangs.
  • Basements and crawl spaces.
  • Garden sheds and storage buildings.

Even a few spiders can produce a surprising number of webs when insect activity is high.

Common Spider Species in the Fraser Valley

Most spiders found around homes in British Columbia are harmless and play an important role in controlling insect populations.

Some of the species we most commonly encounter include:

  • Giant House Spiders
  • Cross Orb-Weavers
  • Cellar Spiders (often called Daddy Long Legs)
  • Wolf Spiders

Although these spiders are generally not dangerous, large numbers of webs around your home can quickly become unsightly and make outdoor spaces less enjoyable.

What Heavy Webbing Really Means

Many homeowners assume the spiders are the problem, but they're often just taking advantage of an existing food source.

Heavy webbing usually indicates:

  • An abundance of flying insects.
  • Exterior lighting attracting insects every evening.
  • Landscaping that's providing shelter for insects.
  • Moisture that encourages insect activity around the home.

Simply removing the webs or spraying the spiders rarely provides a lasting solution if the insects they're feeding on remain.

The Best Way to Reduce Spider Activity

The most effective spider control focuses on reducing both spiders and the insects they rely on for food.

Professional exterior treatments help by:

  • Reducing insect populations around your home.
  • Treating common spider harbourage areas.
  • Removing existing webs during service.
  • Creating a protective barrier around the home's exterior.
  • Reducing the likelihood of new webs forming.

Simple steps such as trimming vegetation away from the house, reducing clutter around the foundation, and switching bright white exterior bulbs to warm-coloured LED lights can also make your property less attractive to insects—and the spiders that follow them.
