Why Are There So Many Spiders In My Richardson Home?

July 15, 2021

If you're seeing spiders inside your Richardson home, there are several key factors to consider. Today, we're going to take a look at life from the perspective of a spider, and discuss some of the reasons why you're seeing so many spiders.

Long before a spider crawls across your floor, it crawls into your yard. If you have lots of spiders in your home, there is a strong possibility that you have lots of spiders just outside of your home. Here are a few things that can make spiders want to hang out near your home.

Moisture. Spiders prefer damp habitats. If the perimeter around your home is moist, you'll have more spiders. Make sure your gutters do not have any obstructions or breaks. Repair plumbing issues. Keep your landscaping trimmed and free of unnecessary vegetation.

Water. Spiders need a drink of water. If you have containers that capture rainwater, or areas where puddles form, you'll provide the water spiders are looking for. This will inevitably lead to spider invasions.

Insects. Spiders eat insects. If you reduce insect attractants, such as open trash cans, exterior lights, and dense vegetation, you'll have fewer issues with spiders.

Debris. This is a unique attractant because it provides the moisture spiders desire and also the bugs for spiders to eat. If you have piles of leaves or wood, you will invite spiders. 


When a spider decides to live near your home, it might create a web and fashion an egg sac. Inside the egg sac, there can be hundreds of eggs. Inside those eggs are spiders that could one day find themselves crawling across your floor or climbing up a wall inside your home. Remove webs around the exterior of your home and also on the interior of your home to reduce spider populations. 

Rotting Wood

Spiders are particularly drawn to rotting wood. This kind of damage reminds them of logs in the forest, or trees with heart rot. They'll climb right inside. If they got into your Richardson home this way, you should repair those damaged areas or fill them in with caulking until you have the money to do a proper repair.


Every home has gaps. When spiders explore your exterior, they can get in through these gaps. Here are a few common points of entry.

  • Old or damaged weatherstripping

  • Missing or damaged door sweeps

  • Damaged door or window frames

  • Gaps around utilities, such as wire conduits and water mains

  • Cracks in foundation walls

  • Unprotected weep holes or vents

  • Gaps in the wood skirting on a mobile home


Sometimes a home will have more spiders because of weather conditions. This is especially true if exterior entry points are not addressed.

  • Excessive rain and flooding can drive spiders to higher ground inside your home.

  • Drought can cause spiders to seek a hiding place from the sun and find their way into humid exterior and interior spaces.

  • Cold temperatures can drive spiders to seek shelter from the cold wind, but more so to find food sources that have gone into hiding.

No Pest Control

Richardson homes that have spiders often have no pest control plan. Routine inspections and appropriate treatments around the exterior of a home will reduce the food sources that attract spiders and provide a barrier that helps to repel spiders. If you're curious how this works, we'd love the opportunity to discuss it with you. If you live in Richardson, Texas, you're in our service area. Reach out to us anytime for assistance.
