It appears that I have a rather decent sized red wasp nest under the soffit in the front of my house. There are about 4-5 different places I have seen them enter/exit from so just sealing them in won't be particularly easy and I can't see or access the nest. I have sat next to the area with a lawn sprayer full of Dawn/wasp spray and killed 10 or so a day for the last several days. While it has turned into a bit of a fun game, I figure I will never be able to get rid of all of them this way. Any recommendations for killing them outside of hiring an exterminator?

move.

You need a residual. The exterminator sometimes use a dust, but the name escapes me at the moment. Kill them prior to closing them up.

I spray Suspend SC monthly around my foundation and windows/soffits, which should last about a month. Even heavily spraying this in the areas where I have seen the wasps go into/out of it they don't seem to be affected. I am thinking about putting a fogger on the end of a long pole and holding that up to the area. Will hit anything that tries to escape with wasp spray. I'm really just too cheap to hire a proper exterminator.

Sticky wasp traps work well, if you have wasps trying to infiltrate a specific area. Keep them out of the view of birds though, they are also attracted to the patterns and colors and you will kill them if they get stuck to it.

Moth balls and hanging toilet bowl deodorizers work amazingly well. It keeps wasps out of the garage, shed and our boat house.

Where do you put these deterrents to keep them out?

Toss a fogger bomb in the attic, then go outside with a few cans of wasp and hornet spray to ambush them at the egress points. After carnage and destruction is over, seal the access points.

I had a monster red wasp nest in one of the eaves of my house. The first time I hit the main access point with spray after tossing the fogger, it looked like the scene in "Independence Day" when all of the little alien fighter ships came out of the mother ship over LA. I prevailed in the end, and it looked like what I can only imagine Custer's Last Stand on the ground after - bodies of red wasps were litered everywhere in a 20 or so foot diameter circle from my attack point. It was awesome.

Nail, over a rafter cross beam, window ledge....really anywhere that you can hang them.


Added bonus for most people: Spiders seem to not like them either. That along with squirrels, rats, mice...etc.


Depending on the size of the area and how long it will be before I go in there again I'll hang two sometimes. One completely unwrapped and one with just one or both ends slightly opened. This way it hits the area hard but you also have one that lasts a while. For a large attic I'd probably put up several. They are cheap and I personally think they smell just fine.


Actually I just bought a house and this reminded me to go put some up in my attic. No pest issues yet and I'd like to keep it that way.

I think exterminators are sometimes worth the money. This would be an instance.

I had the same thing at my house last week.

I came home to find six empty wasp spray cans, a hand pump sprayer, and a ladder lying in my yard.

My wife had asked her brother to remove our gutters (for replacement) and he came across a soffit full of the red wasps.

A couple of weeks earlier, I was cooking on the back porch and could not figure out why so many individual red wasps kept coming around scouting the porch. There were so many that I started killing them with a flyswatter because I thought my guests might encounter one.

I usually leave them alone if they are nesting up high enough not to harm anyone.

So what was the solution? Was the wasp spray enough to get them all?

I guess so. I have not been able to talk to anyone who was involved in the battle. All of my gutters have been removed and are laying on the lawn. There is not a sign of a live wasp anywhere.

I had the same problem in two locations at my house. I was able to get into the attic and spray one nest, the other wasn't accessible. The next that I could spray just kept coming back.

When the weather cools, the wasps become inactive when it stays below 50. Use some spray foam and block off the access points.

Occasionally, I'll still see half a dozen congregate near the old entrances, but they don't stick around long.

Any chance that works with bees?

It should.

They work best in enclosed or mostly enclosed spaces. Not sure where your bees are.

Personally I like this method. It just gets the wasp or bees to relocate. The bees help pollinate things and the wasps help keep pests out of my garden so I usually don't kill them. Occasionally I might take a nest to feed my fish if it is in a bad area. The my cichlids think the larvae is candy.
