What to look for

A honey bee colony in the attic often announces itself with a hum on warm afternoons. Unscreened vents like this one are a common way in.Which bees show up around Corvallis.
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 Corvallis: swarms in spring, and colonies that move into walls. Western carpenter bees, including the big valley carpenter bee, bore into bare wood around Corvallis. Bumble bees nest in the ground or old insulation.
Local bees conditions in Corvallis.
An inspection in Corvallis usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Corvallis'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 Corvallis and Oregon 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. Corvallis sits in a mediterranean climate, and that sets the pace for bee activity here: spring and summer (swarming and colony growth). For Corvallis homes, the area is mostly suburban, 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.
Bees get in through gaps most of us never notice: a loose threshold, a siding seam, a soffit joint. A walk around the house with a flashlight finds most of them.Swarms: what to do.
It's usually calm and moves on within days. Scouts are hunting for a new home. A swarm is a colony on the move. a beekeeper or removal service. Keep people back.
Bees in the wall.
The fix is a cut-out. Bees and comb come out, then the wall is closed. Many homes around Corvallis have crawl spaces, and colonies sometimes settle there too. Homes from Corvallis out to Albany and Salem see the same entry points: soffits, vents and wall gaps. Steady traffic at one gap means a colony inside. Don't seal the hole, and don't just spray it. Trapped bees may come into the house.
Carpenter bees.
They drill round, half-inch holes in bare wood. Carpenter bees look like bumble bees with a shiny, bare abdomen. Painted wood is far less attractive to them. Treat the holes, fill them, then paint the wood.
A year of bees in Corvallis.
- Fall: bumble bee colonies die off. Seal gaps once bees are gone. - Summer: highs near 83°F in Corvallis. Watch for honey stains on walls. - Spring: swarm season, May and June. - Winter: lows near 35°F in Corvallis. Honey bees cluster inside.
Bee, wasp or hornet?
- Wasp: smooth, narrow waist, long legs. - Carpenter bee: like a bumble bee, with a shiny bare abdomen. - Bumble bee: big, fuzzy, black and yellow. - Honey bee: fuzzy, golden brown, about half an inch. - Yellowjacket: bright yellow and black, nests in the ground.
If you get stung.
Wash the area and use a cold pack. Scrape the stinger out quickly with a fingernail or card. 911 for trouble breathing or a swollen face or throat. An antihistamine eases itching.
Live removal: what it involves.
Then they cut out the comb. They open the wall and gently vacuum the bees. A specialist finds the colony, often with a thermal camera. Then the space is cleaned, sealed and closed. The bees go to a managed hive.
What to tell the removal company.
- Whether anyone at home is allergic. - Any stains, sounds or smells inside. - How long you’ve noticed them. - How high up the spot is. - Where the bees go in and out. - A photo or short video, taken from a safe distance.
Ground bees in the lawn.
They're gentle and rarely sting. Small bees over bare spring lawn are usually mining bees. Thicker grass and regular watering make the lawn less inviting. They leave within a few weeks.
Keeping bees from moving back in.
- Cap open pipes, posts and fence rails. - Screen attic, gable and crawl vents. - Seal the entry gap once the bees are gone. - Remove all old comb. Its scent draws new swarms. - Repaint or restain bare wood every few years.
Where colonies settle.
- Grill covers and unused equipment: check in spring. - Meter and irrigation boxes: small, dark and dry. - Sheds and garages: gaps under eaves and doors. - Attics: gable and soffit vents are common entries. - Chimneys: a cap with screen keeps swarms out. - Hollow trees and fence posts: often fine to leave.
Can I just spray them?
Dead bees and comb stay inside, rot, and leak honey. Still, spraying a wall colony usually backfires. Honey bees aren't federally protected. Live removal is usually the better choice. Pesticide labels also limit spraying around bees.
Kids, pets and bees.
Keep pets away from swarms and wall entrances. Teach kids to stay calm and walk away from bees. Cover sweet drinks outside. Dogs stung in the mouth or throat need a vet quickly.
When a swarm shows up.
They have no hive to defend. Swarming bees are usually calm. In spring, a swarm may hang from a branch or fence. A beekeeper may collect it. Keep people and pets back. Most move on within a day or two.

- Paint or stain bare wood to deter carpenter bees.
- Fill old carpenter bee holes after treatment.
