Summer spider activity is ramping up across Poquoson, VA — and coastal humidity is the reason.
The same warm, wet marsh air that brings out gnats, mosquitoes, and moths feeds an explosion of insect prey, and spider populations follow that food right onto porches, into garages, and through crawl space vents. By August, the cobwebs in your garage corner are not the same spider you saw in April — they are generations of new ones.
