I have removed a nest from the door jamb of my vehicle three times in the last two weeks. I have never heard of them building in vehicles, and will be purchasing a repellent to spray where I keep finding the nest. Is it possible for them to have another nest in another part of the vehicle that I can’t see? Should I take the vehicle in to see if they are elsewhere, or will spraying the door jamb keep them at bay. I haven’t seen any hanging around my vehicle, just the one with the nest, and I haven’t noticed them in the yard anywhere. The car is driven most days, and I work in different locations, and I don’t park in the same spot of my driveway all the time. Just a bit concerned since they keep coming back. Thank you for any info you can send my way.
Wasps rely on “scent” to both make and find suitable locations on which to make nests. Once a location is discovered and the process begins, it will most likely be used over and over unless some type of repellent is applied. This is due to the fact that there is a very distinct “scent” applied to the area.
If you review our online WASP CONTROL article, you’ll see a product in there called CYPERMETHRIN. This product is highly repellent to wasps and where applied, they won’t make new nests. It will both cancel out the old scent as well as send out an odor they don’t like and they’ll avoid the treated surface. I suggest you get some, mix it up at the rate of 1 oz per gallong of water and then use a paint brush to apply it to the areas (in this case all door frames) where the activity has been seen. This should stop them immediately and in the past, our experience with this type of problem has shown that one application will stop them for the whole year.
You can also use an aerosol treatment known as PHANTOM. It’s odorless and goes on “dry” so you won’t even see it when applied properly. Phantom doesn’t kill wasps quickly but it will take care of them within 4-7 days. And treatments will last 2-4 weeks. I use it on my boat for wasps and spiders and it works great.
