The insects that are drilling holes in the cedar shingles of our home are smaller than the bees and look to be wasps. Their hole is smaller and often there is a vertical line of them spaced 10 inches or so apart from the next. I have also seen the wasp enter up under a shingle and not return. There is a large yellowish larvae case left on one shingle. Does this sound familiar? Should I use the same products you describe for treatment of carpenter bees? I am here for only a couple more weeks and would be most thankful for a response as soon as possible.
Sounds like HORNTAILS. In fact you are right in thinking they’re some kind of wasp. They are. And they can infest any kind of wood. Horntails are not as common as carpenter bees but they readily infest decks, house siding and soffit areas commonly found on any home.
For now I would suggest you treat the holes with XEMPT DUST. It’s fast acting and will kill them within a day. Treat every hole you can find and in theory, you should be able to knock them all out in one full swoop. Do the treatment at night, when the wasps are most likely in their nests, and by the next morning every nest you treated with a wasp inside will now be housing a dead wasp.
It comes in a jug that can be used to apply but if you have 10 ore more holes to treat, consider getting our HAND DUSTER.
Lastly, to stop new ones from moving in to the same areas as where these nests were located, plan on spraying with MAXXTHOR EC.
Maxxthor is highly repellent to them (and pretty much all bugs) so it will keep the home safe from new activity.

Wow, thank you so much for responding so quickly. I’ll move on this right away as you suggested.
