A Fool’s Proof Guide to Dealing with Crawl Space Pests in Seattle

Dirt crawl spaces in Seattle are the perfect breeding grown for a range of pests! Cheeky rodents, termites, cockroaches are just some of the common Seattle pests that can invade your crawl space. At Parker Eco Pest Control, we see many homeowners struggle to keep rats out of a crawl space! In fact, providing adequate rodent control and crawl space repair is one of our most requested services. So, in this article, we’ll discuss everything you need to know about dealing with crawl space pests in Seattle. 

Help! How Do I Keep Rats Out of My Crawl Space?

Rats dwelling in your crawl space can leave quite a mess behind! Feces, urine, and damaged insulation are just some of the problems you may face. There are a few things you can do when it comes to keeping rats out and away from a crawl space!

Remove damaged insulation: Insulation can retain urine, and it’s a perfect breeding ground for bacteria. In the long run, urine-damaged insulation can lead to increased humidity, odor, and mold growth, all of which can affect your health and well-being. 

Rodent control is key: There are many different ways you can choose to control the rodent population around your home. Talk to us today to learn more about how we handle rats and mice naturally and effectively

When it comes to crawling space rodent control in Seattle, we have your back at Parker Eco Pest Control. Managing rodents like mice and rats within a dirt crawl space will require skilled pest control professionals and time. At Parker Eco Pest Control, we deal with the problem using a 3 visit plan approach. 

So, how do we do it?

  1.  Remove those cheeky pests! Of course, it comes without saying that as part of the pest control protocol, we must remove as many rodents as we can from the crawl space. This may involve setting various mouse traps and baits to decrease the rodent population gradually.  Don’t worry; we have organic pest control options too!
  2. Seal those entry points! Mice and rats can find many ways to invade your home. A skilled pest controller will examine the exterior of your home and crawl space to determine potential entry points and openings. The aim here is to seal any cracks or holes, which decreases the risk of a population of rodents from establishing.
  3. Rodenticides and rat baits for better control: In some cases, we may recommend placing rodenticides throughout your crawl space to control the rat and mice population. 

We Have Options for Pest Control Crawl Space Barriers

Installing galvanized steel mesh along the foundation of your home and sealing off your joists will prevent rodents from damaging crawl space insulation. Buried galvanized steel mesh can also prevent rodents from entering the living area of your home.

Should I remove insulation from my crawl space?

Deciding whether or not to re-insulate your crawl space after a rodent problem depends on a few factors. Dirt crawl spaces are incredibly common in Seattle and it’s estimated that 40% of new construction in the area still relies on this type of foundation (per the NAHB, 2013).  Crawl spaces make accessing your plumbing and wiring for repairs simple and they’re ideal for Seattle’s hilly terrain. These benefits aside, they are extremely vulnerable to rodent problems.

When to leave a crawl space un-insulated

  • If rodents are tunneling into the crawl space (as opposed to chewing in).
  • If your crawl space lacks a permanent rodent barrier such as a rat slab, trench and screen, or rodent-proofed joists to protect insulation (keep reading for more info).

Don’t spend money on new insulation only to have another infestation next winter!

When to re-insulate a crawl space

  • If rodents are chewing into the crawl space and you’ve done a good job sealing off the entry points you could gamble with re-insulating. They may begin tunneling sometime in the future so this is still a calculated risk.
  • If you invest in permanent rodent barrier like a rat slab, trench and screen, or rodent-proofed joists to protect insulation you’ll have peace of mind that your insulation and your living space is safe for the long haul.

What is a permanent rodent barrier?

Exactly what it sounds like! There are three main long term solutions for protecting a dirt crawlspace from rodents:

Rodent-proofing insulation with wire mesh

Traditional fiberglass insulation is by far the most common type we find in crawl spaces. It is also a perfect place for rodents to nest. Protect your new or existing insulation from nesting by installing galvanized steel mesh to the underside of your joists. You’ll get end-to-end protection for your insulation and your living space if a rodent tunnels back into the crawl space.

Trench and screen

To install a trench and screen the soil around your foundation is dug away and galvanized steel mesh is buried against the house to prevent animals from burrowing into the crawl space.

Rat slab

A rat slab is a non-structural layer of concrete that completely seals the dirt floor of your crawl space off from tunneling.

Are rodents chewing or tunneling into the crawl space?

We find that rodents are most likely to access a crawl space by chewing a hole or pushing their way in through a vent. Builder-grade crawl space vents use flimsy mesh that doesn’t stand up to a determined rat. Rodents are also incredible chewers since their teeth grow constantly. They will find a small gap around a gas line and gnaw the opening until they can squeeze through. Sealing off openings and setting poison-free traps are your go-to solution.

Tunneling into the crawl space is also very common. Norway rats are aggressive diggers and they will burrow under the side of the house and pop up in the crawlspace. You’ll need a permanent rodent barrier to stop them from entering once and for all.
