Spiders are creepy crawlies that most people would rather not have in their homes. Unfortunately, spiders can be difficult to prevent, especially during the warmer months. While most spiders are harmless, others can be dangerous and should be eliminated as soon as possible. In this article, we will discuss some common signs of a spider infestation.


One of the most obvious signs of a spider infestation is the presence of webs. Spiders build webs to catch prey, and they will spin webs in various locations around your home. You may find webs in corners, ceilings, and around windows and doors. Most spiders will abandon their webs after a few days or weeks, so if you notice fresh webs appearing regularly, it’s a sign that there is an active spider population in your home.

Spider Sightings

Another telltale sign of a spider infestation is actually seeing spiders. If you spot spiders crawling around your home frequently, then it’s likely that there are more hiding nearby. Spiders prefer dark and quiet areas, so keep an eye out for them in places like closets, basements, and attics.

Egg Sacs

Spider egg sacs are small, round structures that contain several dozen spider eggs. They can be found in corners or crevices throughout your home. If you see these sacs, it’s a clear indication that there are female spiders around who are reproducing.

Shed Skins

Spiders molt their skin as they grow, shedding their old exoskeletons to make way for larger ones. These shed skins can be found near spider habitats and are a good indication of an active spider population.

Bite Marks

While most spiders are harmless to humans, some species can be dangerous. If you wake up with bite marks on your body or notice unexplained bites throughout the day, it’s possible that you have a venomous spider living in your home. Seek medical attention if you suspect that you have been bitten by a dangerous spider.


Preventing spider infestations is possible with a few simple steps. Keep your home clean and clutter-free, especially in areas where spiders like to hide. Seal any cracks or gaps around windows, doors, and foundations to prevent spiders from entering. Use yellow or sodium vapor lights outdoors to attract fewer insects, which in turn will attract fewer spiders. Finally, consider hiring a professional pest control company to help eliminate any existing spider populations.

In conclusion, spiders are common pests that can be difficult to prevent. By keeping an eye out for the signs of a spider infestation and taking preventative measures, you can keep your home spider-free and reduce your risk of encountering venomous spiders. If you do find yourself dealing with a spider problem, it’s best to seek professional help to ensure that the infestation is eliminated safely and effectively.
