Frequently asked questions

The most common pests in Seattle homes are ants, bed bugs, cockroaches, rodents, spiders, termites, and wasps. Professional treatment typically involves a detailed inspection followed by targeted applications in areas where pests are active, along with exterior treatments to help prevent entry. Technicians may also recommend steps to reduce moisture, seal entry points, and limit conditions that support pest activity.

The cost of rodent control in Seattle varies depending on the size of the property and the extent of the infestation. Services may include baiting and trapping, monitoring activity, and sealing entry points around the home. We recommend scheduling a free inspection so our technicians can assess the situation and provide a custom quote.

Our professional rodent exclusion service for Seattle homes typically begins with a detailed inspection to identify entry points and signs of activity. Technicians may seal gaps around the foundation, roofline, vents, and utility lines to help prevent rodents from entering. Trapping and follow-up checks are often included to address active rodents and help ensure the problem is fully resolved.

Seattle homeowners often schedule rodent follow-up or ongoing pest service on a monthly or bi-monthly basis, especially in areas with consistent rodent activity. More frequent visits may be recommended initially to address active issues, with adjustments over time based on conditions around the home. A professional inspection can help determine the most appropriate schedule for your situation.

Our professionals treat carpenter ants in Seattle’s damp homes by first locating nesting areas and identifying moisture conditions that support the infestation. Treatment typically involves targeted applications in wall voids, baseboards, and other areas where ants are active. Technicians may also recommend addressing moisture issues or damaged wood to help prevent carpenter ants from returning.

The cost of termite treatment in Seattle varies depending on the size of the property, the extent of the infestation, and the treatment method used. We recommend scheduling a free inspection so our technicians can assess the situation and provide a custom quote.

Preparing for termite treatment in a Seattle home depends on the type of treatment being used. In some cases, you may be asked to move furniture away from walls, clear access to crawl spaces, or ensure technicians can reach foundation areas. Your technician will provide specific preparation instructions to help ensure the treatment is applied effectively.

Mosquito control for a Seattle yard typically starts in early spring, around March or April, as temperatures begin to warm and mosquito activity increases. Starting treatments early can help reduce populations before they peak later in the season. Monthly treatments are commonly used during the warmer months to help keep mosquito activity under control.

During a mosquito control visit, your local Seattle technician will inspect your yard to identify areas where mosquitoes rest and breed, especially in shaded or damp areas. Targeted treatments are then applied to vegetation, landscaping, and other areas where mosquitoes are active. You may also receive recommendations to reduce standing water and conditions that support mosquito activity around your property.

Our professional pest control treatments are developed with the health and safety of your family in mind, including kids and pets. Western Exterminator uses products registered by the U.S. Environmental Protection Agency and applies them in accordance with label requirements. Your local Seattle technician will explain any safety precautions before or after treatment, including when it’s safe to return to treated areas.
