In our lodge we notice wasps each fall. When we set off a bomb we end up sweeping up hundreds of wasps–set off two bombs this year and we are still sweeping up wasps. Are they coming from the outside or do you think we have a nesting problem inside. What to do?
If you read through our WASP CONTROL ARTICLE, you’ll learn they commonly do this without forming or creating a nest. I suspect this is exactly what you have happening at your lodge each year. I say this because if they were forming or building nests, you’d have activity all spring and summer and most likely during the winter as well. That’s the good news. The bad news is that local wasps in your region clearly overwinter or hibernate and at this point have marked your lodge as a great place to spend the winter. That means this trend will continue and no doubt get worse until you take a pro active approach and start stopping them from entering.
Though setting off TOTAL RELEASE AEROSOLS may kill some, no doubt there are a lot of wasps these treatments will miss. Additionally, more wasps can enter at will as long as the outside of the lodge isn’t treated and protected. If you want better long term results, spray the outside of the lodge with CYPERMETHRIN as explained in our online article. This product is both easy to apply and highly effective on flying pests like wasps. It will not only kill any that attempt to enter but it will also repel them and other perimeter invaders that like to overwinter or hibernate on buildings.
Inside the lodge you can continue using Total Release Aerosols if you prefer but remember much of what they release is wasted. These products tend to spew chemical all over everything and in the long run aren’t the best option to employ. No doubt some crack and crevice treatments with PT PHANTOM would prove to last a lot longer and affect a lot more wasps over time. Since it’s mode of action is slow and deliberate, Phantom tends to affect “grouping up” pests like wasps or other insects which are coming inside to avoid the winter season because these pests like to gather in tight groups when hiding. This enables Phantom to infiltrate and kill so many more you cannot see so in the end, the net result is much better control.
