Are you finding spiders in your Oklahoma home? If so, you're definitely not alone. There is a reason that many spiders are called common house spiders. It's because they commonly get into our homes. But, when you've done everything to seal them out, it can seem like a mystery to find spiders making webs in the upper corners of your bathroom, storage room, or kitchen. Let's take a look at some common ways those common spiders get into our Oklahoma homes.


Each spider has a slightly different way of behaving. How it will try to get in is dependant on what type of spider it is. Spiders that stay low to the ground, like the wolf spider, black widows, and brown recluse, are more likely to get in through an entry point in your foundation wall. Here are a few foundation points these and other spiders will target:

  • Gaps in the seal around window frames. If a spider can find broken caulk on a window, they may be able to get into the void of that window. Once inside, there may be a pathway for that spider to get into your wall voids. And the wall voids of your home can give a spider access to all points within your home.
  • Holes created by insects and rodents. When pests come to nibble on the wood of your home, whether it be a window frame, door frame, or the sill plate of your home, those holes can provide entry for spiders. If you're not familiar with what a sill plate is it is the bottom horizontal beams on your home that the verticle beams (usually 2x4s) are attached to. It is just above the foundation wall. If you have damage on your sill plate, it is likely to be in a secluded location such as under a deck, patio, porch, or stairs.
  • Weather stripping and door sweeps. Over time, the seal around a door can be damaged and gaps can form. These gaps may be more than enough for a spider to squeeze through. If they aren't, they can be made large enough when another pest attempts to get through.
  • Gaps around plumbing. If you have pipes that go through your foundation walls and the seal around them isn't sound, those spiders will quickly take advantage of this entry point.

Exterior Wall

Spiders that make webs and subsist on a diet of flies can target the points listed above and also points above the foundation. They'll explore door and window frames on the first floor and windows above the first floor.


You are probably aware that spiders can scale your walls; the spider webs that often appear under your roofline is evidence of this. But what you may not know is how vulnerable your roofline might be. Most homes have entry points in the rooflines, soffits, or fascia.


Sometimes spiders don't get in through gaps, cracks, and holes. Here are a few ways they can hitchhike into your home:

  • If you purchase a piece of used furniture, you may bring spiders into your home within the voids of that furniture.
  • If you bring a stored box inside from an outside storage location such as a shed, barn, or outbuilding, you could bring spiders inside.
  • If you celebrate Christmas and get your tree from the wrong place, that tree could have spider eggs on it. When those eggs get into the warm interior or your home, the spiders inside might think it is spring and begin to hatch.
  • If you use firewood to heat your home, you could bring spiders in.

How to Prevent Spider Infestations

Since there are so many ways for spiders to get in and finding all of those tiny entry points is difficult, the best way to keep spiders out is to apply a barrier of pest control product around your home. This will reduce populations of spiders and the insects they eat. We highly recommend having a licensed professional install this barrier. When the wrong products are used or when improper amounts are applied, it can present a threat that is far greater than the threat spiders pose.
