I have a new home in Dabney with Vinyl siding. I have seen hornets disappear behind the vinyl siding and I know they're building nests in there. Clever hornets but I'm not too happy about it especially since I'm allergic. Is there a clever way to spray behind there to kill them and their nests? Because spraying the outside of the vinyl doesn't do anything - they are completely protected. And will bug killer effect the waterproofing behind the vinyl? Thank you in advance.

The other day we decided to trim our bushes/hedges and were very surprised when swarms of very aggressive and hard biting small hornets attacked us. They have nests in at least three of the plants and forced us to stop our yard work. We usually do that task in the spring/fall and have never had this problem, wondering if it’s a summer thing? I immediately put in a call to our pest control company and our guy is coming out later this week.

yes, if they are going in and out of the vinyl..........they have a home made already.

Some of your vinyl may need to be removed to find the home(s) and destroyed.

Sure they’re not mud dauber mud wasps? I just seal crack with clear caulk.

From goggle

“The major difference between wasp and hornets is size and colour. Wasps (left) are about one- third inch (one centimeter) to one inch (two and one-half centimeters) long. Hornets (right) are larger. Wasps have black and yellow rings, while hornets have black and white rings”

Another vote for calling a pro.

If you want to do it yourself, you can buy a can of foam (polyurethane?)with a large diameter straw. This will fill the opening more completely than caulk. Depending upon the shape and size of the opening, caulking doesn’t always work.

Check with the Ace hardware store in Wildwood. They seem to have solutions for most problems.

Please make sure it is “minimally expanding” foam or it will blow out the siding. Even then, be careful.

The million dollar question is how big of a nest. A small one I would feel comfortable spraying hornet killer thru the slot in the siding. Repeat if necessary, then caulk the hole. Spray at night when the bugs are inside.
Hornets bite, not sting. Shouldn’t be allergic to a bite? Tho pain and swelling will happen. A large nest, call a pro.

Call someone who knows what they’re doing.

Hornets do not bite, they sting.
