Here in East Texas, I think I have just about every type of wasp and hornet out there. By far, the very worse is the Mahogany Wasp. They are pretty much everywhere, but mostly they love the heat of the attic and you find them on the eaves of a house. During the morning when it's still cool out, they are fairly docile, but once it warms up, they become aggressive. As a contractor that does remodels for a living, I have to deal with them fairly often. I've tried every brand of wasp spray out there and haven't found a single one that will kill them. They will all knock them down, and then you have to step on them quickly to kill them, or they fly away. I rarely see the next since it's inside a small opening in the house, so I just spray the entire can into it and kill what comes out and hope that whats left leaves on their own. This usually works, but it's not 100%. If I can find the nest, saturating it with the spray works better then anything else.
I've been trying to find something to spray on my house and gazebo's that will deter them from building nests. I've been reading labels for awhile now and have never found one that specifically lists Mahogany Wasp's. Seems like all the others are fairly easy to kill, or deter, but not these devils!!!!
