The short version
Around Bellevue, honey bees usually swarm May and June. Swarms are usually calm and often move on. Wall colonies need removal, ideally alive, comb and all. Carpenter bees just need the wood treated and painted.
- Never seal a hole bees are using.
- Wall colonies need the comb taken out.
- Paint bare wood to deter carpenter bees.
- Ask about live removal first.

What to look for
Most bees are helpful pollinators. Trouble starts when they move into a house. A wall colony can reach tens of thousands of bees. Spraying alone leaves comb and honey behind.

A few bees appearing indoors, especially near a sink, a fan vent or a light fixture, often means a colony in the wall has found a gap to the inside.Which bees show up around Bellevue.
Their colonies die off each fall. Small ground-nesting bees in spring lawns are harmless. They're best left alone. Honey bees are behind most calls in Bellevue: swarms in spring, and colonies that move into walls. Western carpenter bees, including the big valley carpenter bee, bore into bare wood around Bellevue. Bumble bees nest in the ground or old insulation.
Local bees conditions in Bellevue.
Bellevue sits in a marine west coast climate, and that sets the pace for bee activity here: spring and summer (swarming and colony growth). For Bellevue homes, the area is mostly urban, so bees pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. An inspection in Bellevue usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Bellevue's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Bellevue and Washington every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options.
Stone walls, hollow fence posts and the space under a deck are favorite spots for bees to settle. Check them in spring before swarm season gets going.Swarms: what to do.
It's usually calm and moves on within days. Keep people back. a beekeeper or removal service. A swarm is a colony on the move. Scouts are hunting for a new home.
Bees in the wall.
Don't seal the hole, and don't just spray it. Trapped bees may come into the house. The fix is a cut-out. Bees and comb come out, then the wall is closed. Many homes around Bellevue have crawl spaces, and colonies sometimes settle there too. Homes from Bellevue out to Kirkland and Redmond see the same entry points: soffits, vents and wall gaps. Steady traffic at one gap means a colony inside.
Carpenter bees.
Carpenter bees look like bumble bees with a shiny, bare abdomen. They drill round, half-inch holes in bare wood. Treat the holes, fill them, then paint the wood. Painted wood is far less attractive to them.
A year of bees in Bellevue.
- Fall: bumble bee colonies die off. Seal gaps once bees are gone. - Winter: lows near 36°F in Bellevue. Honey bees cluster inside. - Spring: swarm season, May and June. - Summer: highs near 76°F in Bellevue. Watch for honey stains on walls.
Bee, wasp or hornet?
- Carpenter bee: like a bumble bee, with a shiny bare abdomen. - Wasp: smooth, narrow waist, long legs. - Yellowjacket: bright yellow and black, nests in the ground. - Honey bee: fuzzy, golden brown, about half an inch. - Bumble bee: big, fuzzy, black and yellow.
If you get stung.
Scrape the stinger out quickly with a fingernail or card. Wash the area and use a cold pack. An antihistamine eases itching. 911 for trouble breathing or a swollen face or throat.
Live removal: what it involves.
Then they cut out the comb. The bees go to a managed hive. Then the space is cleaned, sealed and closed. A specialist finds the colony, often with a thermal camera. They open the wall and gently vacuum the bees.
What to tell the removal company.
- How long you’ve noticed them. - Any stains, sounds or smells inside. - Whether anyone at home is allergic. - A photo or short video, taken from a safe distance. - Where the bees go in and out. - How high up the spot is.
Ground bees in the lawn.
Small bees over bare spring lawn are usually mining bees. They're gentle and rarely sting. They leave within a few weeks. Thicker grass and regular watering make the lawn less inviting.
Keeping bees from moving back in.
- Screen attic, gable and crawl vents. - Cap open pipes, posts and fence rails. - Repaint or restain bare wood every few years. - Remove all old comb. Its scent draws new swarms. - Seal the entry gap once the bees are gone.
Where colonies settle.
- Sheds and garages: gaps under eaves and doors. - Meter and irrigation boxes: small, dark and dry. - Grill covers and unused equipment: check in spring. - Hollow trees and fence posts: often fine to leave. - Chimneys: a cap with screen keeps swarms out. - Attics: gable and soffit vents are common entries.
Can I just spray them?
Dead bees and comb stay inside, rot, and leak honey. Pesticide labels also limit spraying around bees. Live removal is usually the better choice. Honey bees aren't federally protected. Still, spraying a wall colony usually backfires.
Kids, pets and bees.
Teach kids to stay calm and walk away from bees. Keep pets away from swarms and wall entrances. Dogs stung in the mouth or throat need a vet quickly. Cover sweet drinks outside.
When a swarm shows up.
In spring, a swarm may hang from a branch or fence. Swarming bees are usually calm. They have no hive to defend. Most move on within a day or two. Keep people and pets back. A beekeeper may collect it.

right away if anyone in the house is allergic. Call if bees use a gap in your walls or roof. if a swarm hasn't moved on in a few days.

Carpenter bee holes are a fair DIY job. Treat, fill and paint. Swarms and wall colonies are not. A beekeeper or removal specialist can often save the bees.
Bees in Bellevue
Bellevue has a marine west coast climate, and bees activity here tends to pick up spring and summer (swarming and colony growth). For Bellevue homes, most of the housing is urban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. For Bellevue homes, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Bellevue and Washington can point out the specific conditions that matter most here before you commit to a plan. With about 40 inches of rain a year and summer highs near 76°F in Bellevue, spring bloom is steady and swarms are common. Winter lows near 36°F in Bellevue send honey bees into a tight cluster; they don't leave the nest. In denser parts of Bellevue, colonies turn up in walls, soffits, signs and utility boxes.

- Seal gaps in soffits, vents and siding before spring.
- Screen attic and crawl vents.
- Paint or stain bare wood to deter carpenter bees.
- Fill old carpenter bee holes after treatment.
- Remove old comb so new swarms aren’t drawn in.
- Keep empty bee boxes and hives closed up.

Questions people ask
How much does bee removal cost in Bellevue?

Swarms are usually calm and move on within days. A local beekeeper may collect it.
Should I seal the hole where bees are going in?

When do bees swarm in Bellevue?
Usually May and June. A warm, sunny spell after bloom often sets it off.
Do bees come back after removal?
They can, if comb stays or the gap isn't sealed. The scent of old comb draws new swarms.
