Why are there suddenly so many wasps in late summer?
It is the colony's biggest moment. A single yellowjacket nest near a Bellevue home can hold thousands of workers by late summer, and every one of them is foraging. Add cooler nights, a shrinking food supply and rising aggression, and the Bellevue patio becomes the most attractive place around.
Can wasps damage my house?
Unlike termites, they are not wood-destroying insects. The damage Bellevue homeowners actually see is cosmetic: chewed wood on cedar siding, stained drywall below a void nest, and the holes a trapped colony makes escaping. Removing the nest and sealing the gap at a Bellevue home ends it.
What time of day should a wasp nest be treated?
Cool temperatures help. wasps fly poorly below roughly 50 degrees, so a chilly Bellevue morning is a safer window than a warm afternoon. Never treat at night with a flashlight aimed at the nest, since wasps fly toward the light and the person holding it at a Bellevue home.
How do I know if I have wasps, hornets or yellowjackets?
Photograph it from a safe distance and compare body shape. Slender with a narrow waist and long legs means paper wasp; short and stocky with sharp yellow bands is a yellowjacket, the most common stinging problem in Bellevue. Very large, brown-and-yellow wasps flying at night are European hornets, which are established in parts of Washington and around Bellevue.
What should I do if I get stung?
Get indoors calmly; the sting scent draws more wasps. Wash it, apply a cold pack and take an antihistamine. Anyone in Bellevue with hives away from the sting, trouble breathing or throat tightness needs emergency care immediately, and should mention the Bellevue nest so it gets treated.
What is the most common way to get rid of a wasp nest?
Destroying the nest directly. Keep this in mind while inspecting a Bellevue home: in the Moths and Butterflies of New Zealand Trust's mid-2025 survey of 1,055 individuals and 100 restoration groups, nest destruction was the most reported wasp-control method at 43%, ahead of traps at 23% and bait at 13%; the sample is unweighted and from New Zealand. In Bellevue, ask providers to put the number of visits and any re-treatment terms in writing before work begins.
Do wasp traps actually work?
Context for Bellevue, not a local measurement: the Moths and Butterflies of New Zealand Trust's June to August 2025 survey of 1,055 individuals and 100 restoration groups found 23% using wasp traps, well behind the 43% who destroyed nests; the unweighted responses come from New Zealand, not from U.S. homeowners. Local conditions in Bellevue, Washington can differ from the survey population, so confirm the specifics with an on-site inspection.
