Getting rid of wood bees in a shed is pretty easy. If you review our on line article on WOOD BEE CONTROL, you'll learn the first thing you'll need to do is to treat all the nests with a dust. We typically recommend DRIONE DUST which is Ok for small infestations. If you have a lot of wood bee nests to treat, go with the DUST KIT and one of our HAND DUSTERS. Once all their holes are dusted and sealed with our 1/2"CORKS, follow up with a good spraying of CYPERMETHRIN. This will stop new drilling and repel bees and wasps in general so they will stay away.
