Signs of a spider infestation

Arachnophobia is among many people’s biggest fears, so a spider infestation is definitely one many humans don’t want to have in their homes. While most spiders are typically harmless, there may be an underlying reason why they are choosing to infest your property. More often than not though, spiders are just looking for a quiet place where they can build their webs and catch a lot of insects for food.

Below you’ll find out just what may be attracting spiders to your house as well as the common signs that you might have a spider infestation.

What attracts spiders?

Spiders are generally looking for food, but they aren’t looking to bite you. If there are a lot of spiders on your property, this typically means they might have discovered your property is a great place to catch prey. Therefore, a spider infestation might indicate an underlying pest problem.

Signs of spiders

Similar to most pests, spiders become a little more active in the cooler months looking for food and shelter. As the temperature drops in the fall, spiders come out of their hiding spots and look for a mate. This is when these signs are most often spotted. Towards the end of the fall many die off, but some hibernate until the following spring.

If you have a spider problem, you may see one or all of the following:


Spider webs

An abundance of spider webs on your property is one of the biggest signs that you have a spider infestation. Spiders prefer to build their webs outdoors where they are more likely to catch prey. The size and shape of spider webs will vary by species. Some are orb-shaped while others are funnel-shaped.

Spider webs in your bushes can lead to a larger infestation as these spiders will start to lay eggs and produce spiderlings. The baby spiders will then look for another place to set up their own webs, possibly leading them inside your home.

Egg sacs

Spider eggs are laid into a silken sac carrying about 100 eggs in each sac. These sacs may be fixed to a surface, hidden in the web, or carried by the female. Signs of the sacs fixed indoors indicate that soon there will be more spiders around. Once the eggs hatch, hundreds of those baby spiders can come out, crawling all over the walls and getting into the tiniest spaces and cracks. Given a spider’s cannibalistic nature, they try to spread out and away from each other and might end up all over your home and inside.

Spider nests

In addition to making sacs out of their spin silk, spiders will also use their silk to create nests to live in and wait for any prey to come close enough to catch. Spiders will build nests in your home if they are comfortable enough and feel like they have plenty of food nearby. They typically like to build their nests in dark, undisturbed areas of the home like the corners of rooms near the floor or ceiling.

Live or dead spiders

Of course, seeing multiple live or dead spiders around your home is a fairly good indicator that you have an infestation. There are thousands of species of spiders, each preferring a different type of environment for their home. It can be hard to tell what type of spider you are dealing with, so it’s best to contact us for proper identification and removal.

Where should I look for signs of spiders?

In general, spiders can be found in dark, secluded areas, both in your home and garden. Some spider species live in burrows rather than webs, while others are free-ranging and take refuge in crevices. Some species of spiders are attracted to moist environments, so make sure you check your basements, walls, sheds, and other damp locations. Other species can be found in places such as attics, the junction of a wall and ceiling, closets, and storage boxes.

Spiders feed on other insects and prey on ants, flies, woodlice, and other spiders, so where there is a plentiful supply of other insects, spiders will wait to find their next meal.

Is your house infested with spiders?

If you see signs of a spider infestation around your home, then there could be a reason they are choosing your home as the place to build their webs. It could be something like an infestation of flies or an increased amount of mosquito activity around your home.

Part of an Ehrlich home inspection to determine if your property has a spider infestation is looking for those contributing factors. Often the best way to eliminate a serious spider infestation is to get rid of their food source, so a number of different pest control and specific spider control and prevention methods may be needed.

At Ehrlich, we offer expert identification of your invading spider species and provide a professional service to control larger infestations.
