Why Are There So Many Spiders This Year?

Out of all the common pests we see throughout our lives, spiders are among the most feared. Maybe it’s their long, spindly legs, the sticky webs they weave to catch their prey, or the way they skitter across surfaces at an alarming rate. No matter what your reason, it’s normal to dislike these 8-legged creatures.

So if you’ve noticed an influx in spider populations this year and aren’t too happy about it, we get it. We’re pest control specialists, after all, and we talk with customers every day who need help keeping spiders out of their homes. Let’s talk about what has happened lately to increase the number of spiders people are seeing, and what can be done to keep your house and yard a spider-free zone.

The Recent Princeton, NJ Spider Problem

You may remember the reports about the Joro spider in 2024. These flying, venomous spiders native to East Asia were spreading to New Jersey and Delaware, and the public was not pleased (to say the least). But the Joro spider—black, yellow, and about the size of your palm (with the possibility of growing up to 4 inches) certainly isn’t the only one to keep an eye out for.

New Jersey also encounters its fair share of black widows, brown recluse spiders, and yellow sac spiders, all of which are harmful to humans. A couple of theories are floating around as to why people have seen more of these this year than usual:

• Weather conditions. New Jersey experienced an especially warm, wet spring in 2025, which led to higher populations of insects that favor this type of weather. That means more meals to attract hungry spiders, many of which mate and begin reproducing around late summer and early fall.
• Spiders will eat lots of different insects, but they’re especially drawn to cicadas. Since there were higher populations of this particular insect this year, the spider populations also flourished.

How to Keep Spiders Out of Your House in Princeton, NJ

When it comes to spider control in Princeton, NJ, there are lots of DIY steps you can take to help keep these creepy-crawlies out of your home and away from your family and pets:

• Clean your home and dust regularly to prevent undisturbed spaces where spiders will lay eggs and weave their webs.
• Remove any outdoor clutter in your garage or yard where spiders could make themselves a cozy home.
• Switch to outdoor lighting with warmer bulbs, such as yellow, orange, or even red. Cool light attracts insects, which in turn attracts spiders looking for their next meal.
• Be sure to periodically check your home for eggs. They’ll typically be found in dark, hard-to-reach places, like underneath end tables, in unused cupboards or drawers, or even in outdoor places like your garage or porch.
• Store items, including food, in airtight containers.
• Keep garbage cans away from your home and make sure they have tight lids that will stay closed.
