Why You’re Seeing More Rodents in Tumwater After Rainstorms

Table of Contents

You’re not imagining it. Rodent activity does spike in Tumwater after every rain. Washington regularly deals with rodent infestations. If you’ve heard more noise in your attic or seen fresh droppings in your crawl space, you’re not alone. Heavy rains push rodents out of their burrows and into homes across Tumwater, Olympia, and the rest of Thurston County.

In this guide, we’ll discuss how rainstorms trigger rodent activity and show you how to spot rodent infestation warning signs so you can take action fast. You’ll learn why Tumwater houses are especially at risk from rodent problems, what you can do to prevent them, and how to deal with rodents that have already moved into your home. 

We’ll also share tips on effective rodent control and the benefits of hiring a professional pest control company to handle the problem for good.

Key takeaways:

  • Rain floods rodent burrows, forcing them to seek shelter in homes.
  • Tumwater homes are vulnerable to rodent problems due to their natural landscape and aging infrastructure.
  • Common signs of rodent infestation include droppings, scratching noises, and chewed materials.
  • Professional rodent control and exclusion are the best solutions against rodents.

How Rainstorms Trigger Rodent Activity

The Pacific Northwest, especially the Puget Sound region near Tumwater, is home to a diverse range of rodents. Mice, rats, and squirrels are some of the most common critters in the area, and they’re always on the lookout for dry, warm shelter. So, when heavy rain hits Tumwater and floods their nests, they scramble to find higher ground quickly. To rodents, higher ground often means your home, garage, or shed.

Rodents can easily find their way into homes in older neighborhoods near the Deschutes River or parts of Tumwater, particularly those with aging infrastructure. Cracked foundations, broken vents, and unsealed crawl spaces often provide entry points for rodents.

Once they’re inside, their damage starts quickly. Rodents will chew through electrical wires, increasing the risk of short circuits and potentially leading to fires. They may also nest in your home’s insulation, tear up stored belongings in the attic, and leave trails of droppings that carry harmful bacteria. On top of that, these critters breed fast. 

A small population of rodents can quickly turn into a full-blown rodent infestation in just a few weeks. 

Common Signs of a Rodent Infestation

After a rainstorm, keep an eye out for:

  • Scratching sounds in walls or ceilings
  • Fresh rodent droppings around pantries or along baseboards
  • Chewed food packaging or insulation
  • Greasy rub marks near entry points

If you spot any of these signs, it’s best to act quickly. Rodent infestations can escalate rapidly in damp conditions.

Why Tumwater Homes Are Especially at Risk

Tumwater’s mix of forested greenbelts, aging homes, and steady rainfall creates the perfect environment for rodent problems. Homes near the Deschutes River, wetlands, or wooded areas are especially vulnerable, as rodents follow the water and shelter sources.

For homeowners in Tumwater and surrounding areas, the risk isn’t limited to just fall or winter. Thanks to Thurston County’s consistent rain, rodent infestations can happen year-round. Without proper prevention, even a short downpour can lead to a severe pest problem inside your home. 

More importantly, rodents can pose serious health risks to you and your family. Rodents carry harmful diseases like hantavirusleptospirosis, and salmonellosis.

How to Prevent Rodents From Getting Inside

The best way to stop a rodent infestation is to block it before it begins. Homeowners in Tumwater can take these simple but effective steps to keep rodents out in the first place:

  • Seal entry points: Inspect your home’s foundation, utility lines, vents, and siding for gaps or cracks. Mice can squeeze through holes as small as a dime, so seal up even the tiniest openings.
  • Clean your crawl space: A damp, cluttered crawl space is prime real estate for rodents. They love to nest in insulation and hide in dark, secluded areas. Keep the area dry, well-lit, and clutter-free.
  • Keep food sealed: Use airtight containers for pantry goods and pet food to prevent spoilage. Leaving food out, even in garages or storage rooms, can attract rodents and pests like roaches quickly.
  • Trim back vegetation: Keep plants trimmed and away from your foundation. Overgrown bushes and tree branches can serve as bridges for critters seeking shelter from rain. Over-reaching branches can lead rodents straight to your roof or siding.

What to Do If You Already Have Rodents

If you’re facing an active rodent infestation, it’s time to call in the experts. Although numerous DIY rodent removal tips may be available online, we strongly recommend leaving rodent removal to trained professionals. Attempting to remove them by yourself may put you at risk of injury. You could also cause more damage to your property if the rodent becomes aggressive or escapes during your DIY removal attempt.

FAQs

Why do rodents come inside when it rains?

When rain floods rodent burrows, they search for dry ground. Your home offers warmth and protection, making it an ideal shelter. Attics, basements, and crawl spaces are common entry points for pests. Rodents can squeeze through tiny gaps, so even small cracks in your foundation can let them in.

What should I do if I see rodent droppings in my crawl space?

Fresh droppings typically indicate an active infestation. Call a licensed exterminator for an inspection and targeted rodent control plan.

Can I prevent rodents without using traps?

Yes. You can prevent rodents by sealing entry points and keeping crawl spaces clean, without using traps inside.
