The answer to 'why is my spider nests' is that spider nests are typically caused by common household spiders seeking a safe, quiet place to build their webs and lay eggs. Spider nests are often found in dark, undisturbed areas like corners, attics, sheds, or under furniture. Symptoms of a spider nest include seeing multiple spiders, finding egg sacs, or noticing an increase in cobwebs.
For most homeowners, spider nests are a nuisance but not a major pest problem. Simple DIY solutions like vacuuming, sealing cracks, and removing clutter can help eliminate spider nests. However, if you have a severe spider infestation or are dealing with venomous spiders, it's best to call a professional pest control technician to safely remove the nest and prevent future issues.
