Stinging and Flying Insect Control in Whatcom and Skagit County
Call 360-410-2199 Request a free inspection
Pacific Northwest summers bring a surge of stinging and flying insects. Wasps, yellowjackets, and bald-faced hornets build aggressive nests under eaves and in the ground, while cluster flies push into walls and attics to overwinter around Bellingham, Ferndale, and Mount Vernon.
Sasquatch Pest Control locates and treats nests at the source, blocks the entry points flies use to get inside, and puts a protective barrier around your home. We are a local, family-owned company with no long-term contracts.
Services We Offer
Wasp Control — Wasps, yellowjackets, and bald-faced hornets are removed fast and safely. Sasquatch clears nests and uses repellent sprays and pre-treatments to discourage future nesting.
Yellowjacket Control — Yellowjackets are the most aggressive stinging insect Whatcom County homeowners face, with colonies growing through late summer and fall. Sasquatch locates and treats nests safely, including nests in the ground and inside wall voids.
Bald-Faced Hornet Control — These insects build large, gray, football-shaped paper nests and are highly defensive, swarming to sting anyone who ventures too close. Sasquatch removes the nests safely rather than knocking them down.
Carpenter Bee Control — Carpenter bees bore tunnels into untreated wood on decks, fascia boards, and eaves. Sasquatch treats carpenter bees at the source and can advise on sealing and finishing the wood so they do not return to the same timber.
Bee Control Services — We provide safe, responsible bee control. We do not treat honey bees. Where a honey bee colony needs to move, we will connect you with a local beekeepers association that can carry out a live removal and relocate the bees.
Cluster Fly Control — Cluster flies sneak into attics and walls by the hundreds in fall and winter, then reappear indoors on warm days. Sasquatch treats and seals against them.
Drain Fly Control — Drain flies, also called moth flies or sewer gnats, breed in the gelatinous organic film lining slow drains. Sasquatch finds and eliminates the breeding sites rather than just killing the adults you can see.
Fruit Fly Control — Fruit flies persist into late summer and fall, drawn to ripening produce and fermentation. Sasquatch tracks down and treats the breeding sites.
House Fly Control — House flies breed in garbage and decaying matter and can spread bacteria such as E. coli and Salmonella. Sasquatch treats infestations at the source.
Fungus Gnat Control — These tiny flies breed fast in overwatered plants and damp areas. Sasquatch treats the infestation at the source and advises on the watering and moisture conditions feeding it.

Common questions
Can you remove a wasp, yellowjacket, or hornet nest safely?
Yes. Our technicians are equipped to treat and remove nests in eaves, wall voids, and the ground while protecting your family and pets. Bald-faced hornets and yellowjackets can be aggressive, so please don’t attempt removal yourself.

Why do flies suddenly appear inside in fall?
Cluster flies overwinter in wall voids and attics, then emerge on warm days. We treat and seal the areas they use so they can’t keep coming back.
Do you treat honey bees?
No. Honey bees are beneficial pollinators, so our own work stays on wasps, hornets, yellowjackets, and carpenter bees. If you have a honey bee colony that needs to move, we will point you toward a beekeeper who can remove them alive and relocate them.
