Mercer Island Pest Control & Exterminator Services

Tucked into Lake Washington between Seattle and Bellevue, Mercer Island is a green, wooded community where forested lots and lakefront homes sit close to the water. That green setting also gives pests easy access to your home.

From rodents in the crawl space to carpenter ants in damp wood and wasps under the eaves, Guard Pest Control provides the pest control Mercer Island homeowners and businesses count on. Since 2013, we've protected King County properties with local, family-run service. Let us be your shield against pests.

Comprehensive Pest Control Services for Mercer Island Homes & Businesses

We handle the pests common to the Pacific Northwest, with pest control services built around your property, from a lakefront home to a local business.

Eco-Friendly & Family-Safe Pest Management

We use Integrated Pest Management (IPM), which means we treat the problem at its source and choose products that stay safe around your kids and pets. You get effective pest control without unnecessary chemicals, applied by exterminators who explain each step.

Comprehensive Crawl Space & Home Exclusion

On a wooded island, keeping pests out matters as much as clearing the ones inside. Our crawl space and home exclusion work seals the gaps, vents, and entry points rodents use to get in, protecting your home from the outside in.

Targeted Exterminator Solutions for Common Pacific Northwest Pests

Different pests call for different treatments. Here's how our exterminator services handle the ones Mercer Island sees most:

Mercer Island Rodent Control (Rats & Mice)

Rats and mice are a constant on a wooded, lakefront island. They slip into crawl spaces, garages, and walls for food and shelter. Our rodent control clears active infestations, seals the entry points they use, and sets up prevention so they stay out.

Ant Control & Carpenter Ant Extermination

Ants are one of the most common calls we get, from odorous house ants in the kitchen to carpenter ants tunneling into damp or damaged wood. Store-bought sprays often make it worse by causing the colony to split, or bud, into new nests.

Our ant control goes after the whole colony instead, using a perimeter barrier the ants carry back to the nest, along with professional advice on limiting the food and moisture that draw them in.

Spider, Stinging Insect & Wasp Removal

Spiders move indoors from the woods and lakefront, while wasps and hornets build nests under eaves, decks, and play areas. Our exterminators clear webs and nests, remove nests safely, and treat the spots where they rebuild, so your yard is comfortable again.

The Guard Pest Control Process: 4 Steps to a Pest-Protected Home

Our process follows four simple steps:

  • Inspect: We start with a free inspection to find the pests, entry points, and conditions that draw them in.
  • Treat: We treat the problem at its source with targeted, family-safe methods matched to the pest.
  • Protect: We set up a perimeter barrier around your property and seal the entry points rodents use, so pests stay out.
  • Follow Up: We check back and return on a quarterly schedule. If pests come back between visits, so do we, at no extra cost.

The cost was high for a one time treatment, but still very competitive with other pest control services. I’d definitely recommend them.

Frequently Asked Questions About Pest Control in Mercer Island, WA

How often should I schedule professional pest control services in Mercer Island?

For most Mercer Island homes, a recurring plan every quarter gives the steadiest protection, since Pacific Northwest pests stay active much of the year. An active infestation may need a visit or two up front, and from there, our regular quarterly maintenance prevents future pest issues.

Are your exterminator treatments safe for pets and children?

Yes. We use family-safe, eco-conscious products and apply them carefully. Your technician will let you know if you need to do anything before or after a visit, like keeping pets off a treated area until it dries.

What is the most effective way to eliminate rats and mice on Mercer Island?

The most reliable approach pairs removal with exclusion. We remove active rodents, seal the crawl space gaps they use, and correct the conditions that draw them in, so the problem doesn't simply return.

Do you offer one-time exterminator services or only recurring plans?

Both. You can book a one-time treatment for a specific problem, or set up a recurring Protection Plan for year-round coverage. We'll help you choose what fits your home and budget, with no pressure either way.
