Why Are the Spiders So Bad This Year? Is Climate Change to Blame?

If it feels like you’re seeing more spiders around your home this year, you’re not imagining it. Many homeowners across Metro Vancouver and the Lower Mainland have been asking the same question: Why are there so many spiders this year?

While spiders are a normal part of our ecosystem, several factors can lead to noticeable increases in spider activity. One of the biggest questions people ask is whether climate change is making spider problems worse.

The Short Answer: Yes, Climate Change May Be Contributing

Warmer temperatures, longer growing seasons, and changing weather patterns can all influence spider populations. While climate change isn’t the only factor, it can create conditions that allow both spiders and the insects they feed on to thrive.

When insect populations increase, spiders have more food available. More food means more spiders surviving, reproducing, and moving into areas around homes and businesses.

Mild Winters Mean More Spiders Survive

In British Columbia, harsh winter conditions traditionally help keep many insect and spider populations in check. However, recent years have seen milder winters and longer warm periods.

When fewer spiders die off during winter, more survive into spring and summer. This can lead to larger populations throughout the year.

More Insects Mean More Spiders

Spiders don’t appear out of nowhere. They follow their food source.

Common spider prey includes:

• Flies
• Mosquitoes
• Moths
• Ants
• Beetles
• Wasps

If your property has experienced an increase in flying insects this year, spiders will likely take advantage of the abundant food supply.

Outdoor lights, standing water, gardens, and dense landscaping can all attract insects, which in turn attract spiders.

Why Are Spiders Coming Inside My House?

As summer transitions into fall, many spider species become more visible. This is often their mating season, which causes them to wander more frequently.

Spiders commonly enter homes looking for:

• Shelter from changing weather
• Food sources
• Mates
• Safe places to lay egg sacs

Cracks around windows, doors, foundations, vents, and utility penetrations provide easy entry points.

Are Spiders Dangerous?

The good news is that most spiders found in British Columbia are harmless to humans.

In fact, spiders are beneficial predators that help control nuisance insects. However, large numbers of spiders, excessive webs, and frequent sightings inside the home can become frustrating and unsettling for many homeowners.

Some people also suffer from arachnophobia, making even harmless spiders a significant source of stress.

How to Reduce Spider Activity Around Your Home

Here are several steps homeowners can take:

Reduce Outdoor Lighting

Bright exterior lights attract insects, which attract spiders. Consider using warm-colored LED bulbs or motion-activated lighting.

Seal Entry Points

Inspect your home’s exterior and seal gaps around:

• Windows
• Doors
• Utility lines
• Foundation cracks
• Vents

Remove Webs Regularly

Removing webs discourages spiders from establishing long-term territories around your property.

Reduce Clutter

Basements, garages, crawl spaces, and storage areas provide excellent hiding spots. Keeping these areas organized can reduce spider harbourage.

Control Other Insects

The most effective spider control strategy is often controlling the insects they feed on.
