Carpenter/wood bee extermination

I think they sell some traps to catch them and I also see no reason why spraying some insecticide on the house wouldn't work....however, that wouldn't be nearly as fun as a tennis racket...

I recently saw somewhere where someone made a cheap trap that worked great. I saw it either on here or reddit, can't remember.

Had the same problem when I moved last year. I went after them with a racket last year and thought I made a good dent in the population. But this year they came back twice as strong. I learned that around every hole there are at least 2 bees. The male bee is the one on the outside defending the hole and the female is inside the hole having babies and making it larger. The racket usually only allows you to get the male and not the females and babies when they hatch. So I went to Chastamt Bros. in Lafayette and got 2 different sprays. The first spray I had to spray in an around the holes the bees have made. This killed all the bees it came into contact with. The next day there were dead bees everywhere and hanging out of the holes. The second spray was a repellent that drives away any bee that wasn't killed. They then recommended caulking the holes, and reapplying the repellent before the start of spring next year

I have done the tennis racket thing. However, when I got to about 75 and they were still around I gave up. They were in the privacy fence and something about the location made it the ideal home, ie, when the original tenants got swatted many were in line to replace them. (and I realized if I killed 75 with tennis racket and they never stung me, they weren't much of a threat). SO, try something on the professional side, sprays or whatever.

WD-40 in every hole, take the red stem and put it as deep as you can in the nest, wait a while bee comes out and dies. then fill hole with spray foam or anything to stop easy access, Tennis racket is fun.
