Carpenter bees out of reach! Anything that can be done?
There are a few carpenter bee holes high up and out of reach without a more significant ladder than I care to mess with at the moment. The holes are right under the roof, about 40 feet off the ground. There is a upper-level porch that is roughly even with them vertically, but about 15-20 feet beside them.
The ideal and long term solution seems to be to use a drione or similar pesticide dust and spray into the holes with a puffer. But not being able to access the holes directly, the best I can do is spray a liquid carpenter bee aerosol stream from the porch and repeat often.
Outside of getting a big ladder or hiring a professional, are there any other tricks to help a DIYer like myself?
