rodger. Posted August 27, 2017 Report Share Posted August 27, 2017 I have some wasps getting in (and I assume making a nest) behind a small roof overhang on the front of my home. They are wiggling in through a brick mortar joint, and heading up under the eave. I have used a full can of foam, as well as some insect dust with 0 effect. I may break down and call an exterminator. Any ideas? Quote Link to comment Share on other sites More sharing options...
minorhero Posted August 27, 2017 Report Share Posted August 27, 2017 They make foam that has insecticide in it so as they eat the stuff they die. I saw it at home depot a while back. Also buy some wasp killer stuff. The kind thats liquid and squirt some of that up there. And finally theres always the option to ignore them. They won't eat your house and there will always be something around like this. The most an exterminator will do is squirt more poison in there under a bit of pressure which the can of wasp killer is going to get you already. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Tpt life Posted August 27, 2017 Popular Post Report Share Posted August 27, 2017 Northern clime? Wait until winter kills them. Plug the holes with mortar caulk early next spring. 3 Quote Link to comment Share on other sites More sharing options...
Popular Post Mick S Posted August 27, 2017 Popular Post Report Share Posted August 27, 2017 Also, wait until dusk to spray the wasp killer up there - once they've returned to the nest and calmed down for the night. 3 Quote Link to comment Share on other sites More sharing options...
Marmotjr Posted August 27, 2017 Report Share Posted August 27, 2017 I've also seen this done with a shop vac. I'm not sure if you can reach this part of your house easily from the ground though, the pics are a little confusing to me in that regard, but I'm guessing from the angles and the plants, its about head height? Build a quick and dirty frame to hold up the shop vac hose/tube right up to the opening they are using. Turn it on and run away. Wait a while till they stop swarming and are sucked in, then spray some wasp spray into the shop vac hose. Keep it running and pop the hose off and spray some more into the barrel. Slap a piece of duct tape over the opening and then you can turn it off. I'd wear something heavy like carharts just in case, unless you want to spring for a bee/wasp suit. This should have removed most of the wasps from the nest, and then you can use the fillers as mentioned above. If you don't get the wasps out first, they may try to find a new path out of their nest, and that may be into the house, or through another hole.

Tpt life Posted August 27, 2017 Report Share Posted August 27, 2017 This is a heater vent clearance. I do not like the thought of bug spray in there. Just me. That is why I would wait it out. Quote Link to comment Share on other sites More sharing options...
Bankstick Posted August 27, 2017 Report Share Posted August 27, 2017 Not much you can do, IMHO. Not sure about the insecticide in the foam. Check the label. Spraying in the vent shouldn't hurt anything or anyone. Air movement should be directed outside. I don't think they will go away. Winter will push them deeper to find warm places. We have yellow jackets in the ground. Winter doesn't faze them. My wife sprays the hole when we see them. I am taking shots for wasp and white faced hornet venom. Had a severe reaction about 15 years ago to some sort of bee but these are what the tests showed. Never had any reaction before in my lifetime.

Its hilarious. The only additional thing I would recommend is to video tape the whole thing, then share it here if you would be so kind ;P 3 Quote Link to comment Share on other sites More sharing options...
wdwerker Posted August 27, 2017 Report Share Posted August 27, 2017 Stuff a little steel wool in cracks before you foam them. Rodents won't chew it, maybe it will piss off the bugs too ! 1 Quote Link to comment Share on other sites More sharing options...

A couple pro exterminators that post online use this technique to clean out the hives before removing them, helps save nasty surprises later. Beat wasp video I saw was taking a quadcopter up near the hive and letting the blades chop up the wasps as they swarmed on it. And then he chopped away at the hive with it too.

Wasps congregate, leaving most of the mass to die on the outside and far fewer (and much weaker) to deal with after winter. Quote Link to comment Share on other sites More sharing options...

I just soak a paper towel with acetone, suck that in, turn the vac off, leave it, and it turns the vac into a big Killing Jar. I did that once, and left it over the weekend, and it still smelled like acetone on Monday. They aren't smart enough to crawl back out the hose. All wasps were dead. I have a bunch of extra extensions for shop vac wands, and get about ten feet away. 1 Quote Link to comment Share on other sites More sharing options...

I use Acetone vapors to smooth ABS 3d prints, and it will leave the print a lumpy mess if you leave it exposed to the vapors for too long. I doubt shop vac bins are ABS, but there a few in the family that Acetone is a solvent for. Quick google search will tell you. Quote Link to comment Share on other sites More sharing options...
Tom King Posted August 27, 2017 Report Share Posted August 27, 2017 Yeah, I use acetone to smooth, and polish golf club ferrules. The Rigid vac was not empty when I sucked the paper towel in, so I figured it wouldn't be resting on the plastic anyway. That same vac has been used for several years since then, with no ill effects. Good point about being careful with Acetone. Carburetor cleaner will dissolve some plastics too. Quote Link to comment Share on other sites More sharing options...
Popular Post Denette Posted August 27, 2017 Popular Post Report Share Posted August 27, 2017 Hope you get your wasps killed, Rodger! I'm just popping in to say that whenever I'm in the shop and a wasp flies in, I spray shellac on it. It's aerosol and it's handy. They sink like a rock and waddle away. I feel evil. 3 Quote Link to comment Share on other sites More sharing options...
Popular Post rodger. Posted August 27, 2017 Author Popular Post Report Share Posted August 27, 2017 Well, I'm giving the shop vac method a try. Seems to be working fairly well. The attraction to return to the nest must be very strong, as they are willing to risk flying in front of the vac, even after buzzing around it to check it out. Been running about an hour, and I've got at least two dozen wasps sucked up. 5 Quote Link to comment Share on other sites More sharing options...
rodger. Posted August 27, 2017 Author Report Share Posted August 27, 2017 When I'm done sucking them up, I think I'll just put the whole vac in a plastic bag and tie it off for a few days. That should do the trick just fine. Clearly, I'm not going to get them all. Is the next step to just seal it up? Quote Link to comment Share on other sites More sharing options...

Might want to bang on the wall with a rubber mallet or something if you feel brave enough, try to piss off the rest inside. They'll come out to attack get sucked in. Don't forget to run away quickly! Yeah, I'd just seal it up with something, after spraying some wasp killer up inside of it (as long as it doesn't get into the duct work like C mentioned). Hopefully there won't be enough left to mount a counter offensive. Quote Link to comment Share on other sites More sharing options...

I'll leave it run for a bit longer and then remove it, seal off the hose, and pack it up for the night. May need a 2nd round tomorrow.

I know this seems silly, but she has been following me like a shadow for this whole process to ensure I don't kill any! LOL. 1 Quote Link to comment Share on other sites More sharing options...
wdwerker Posted August 28, 2017 Report Share Posted August 28, 2017 Has she been stung by one yet ? Sometimes the only way we learn is by personal experience. If she still voices that opinion after being stung then it has some validity. Maybe you could dispose of them after bedtime ? Quote Link to comment Share on other sites More sharing options...
