I HAVE A SEVERE PROBLEM WITH CARPENTER BEES ON MY WOODEN PORCH. THEY ARE BORING HOLES EVERYWHERE AND HAVE SAWDUST ALL OVER EVERYTHING. I’M NOT SURE WHICH ITEM WOULD BE THE BEST I COULD USE TO SPRAY THE WOOD STRUCTURE TO ELIMINATE THEM.
Bee sawdust is being generated by the carpenter bees as they chew through the wood of your porch. This can quickly be stopped by spraying it with the CYPERMETHRIN we have featured in our CARPENTER BEE CONTROL ARTICLE.
For bee nests which are active – the ones where you see bees entering and exiting – you will need to treat with some DRIONE DUST. This will get both the live stages and any that are buried in the nest developing. Be sure to plug the nests with a 1/2″ CORK to seal the dust up so it can last as long as possible.
