Now I know this isn’t the most interesting or exciting blog post you’ve read, but I do know that it could be very helpful for some people!
Our house is made of cedar siding and everyone told us that the cedar siding would be a pain to maintain but I didn’t care! Even the millions of bee holes didn’t scare us away!
We moved in the house in August so the bees weren’t too active. It wasn’t until spring time when we realized how bad the issue really was. We would walk outside and there were literally 50 bees all over the house. It was to the point where I was afraid to walk to my car because their were so many! So I did some research to figure out how to get rid of these little rascals.
After doing plenty of research I finally decided to try out some products I had read about. I read that to kill the active nests you have to put an insecticide dust into the holes. The dust will kill the bees in the holes and their larvae. But then you also have to treat the wood so that the bees can’t smell it anymore. So, here’s what we ended up using and it was below $100! ($84 to be exact)
DeltaDust – this is what goes in the holes
Duster– to spray the dust in the holes
Demand CS – this is what we sprayed on the whole house to seal the wood
1-Gallon Sprayer– to spray the DemandCS
Make sure you read the directions completely on both products! We both wore gloves because these are very strong chemicals. In the end I wish I wore a mask too because when I was spraying the solution there was some mist that would fall back in my face because it was windy and by the end of the day my face was super red and burning. I probably got a small chemical burn from it, so be careful!!!
I started out putting the dust in the holes while my husband sprayed the siding. It really creeped me out at first because I would put the dust in the hole and in a few minutes we could hear the bee buzzing around because it was trying to get out of the hole. Then it’d come out all white and it would either fall to the ground dead or it would fly around like it was drunk and end up dying at some point. It creeped me out because there were so many but then it turned out to be kind of cool because I felt like we were getting somewhere! I went around and dusted every single hole I could see and then we sprayed every piece of cedar wood/siding on the house. Unfortunately this wasn’t a quick process. We have a 2,000 sq. ft. one story house and it took us literally all day. We also needed a tall ladder to get the top of the house and the back. In the end we probably killed close to 100 bees which is insane to think there were that many living in our siding!
It’s been over 3 months since we did this and I still find some dead bees which most likely means they came and found a hole and then got killed by the dust. The Demand CS says it lasts 3 months but it seems like it’s lasting longer. I’m hoping we can make it until next spring before we have to do another coat of it.
My tip is to save some dust because you’ll probably miss a few holes. I missed a few that were up underneath the bottom banister of our railings and I missed a few up under our window seat on the back of the house. They’re some sneaky little suckers!!
I do feel bad for killing so many bees but when they become a problem with the structure of your home there is really nothing else you can do. I’m hoping that now we can just prevent them from coming back so that we don’t have to kill anymore!
I hope this was helpful for you if you’re dealing with carpenter bees. I was getting really frustrated because I couldn’t find any helpful articles on exactly what to do. I cannot tell you for sure if this will work for you but it has worked for us and has been a blessing!! So if you’re looking for a cheaper way to get rid of carpenter bees than paying someone else to do it I would suggest doing this!
