Hi, The entry to the wasp's nest is ground level, on the outside wall of the garage. It has become a real safety concern, as I have two young children that play in the yard. I've read a number of suggestions in dealing with them, and have so far tried one (which doesn't work), but wonder if I should leave it to a professional? Thanks!!
I prefer to use the aerosol foam products for wasps nests, it shoots from about 6 or 8 feet and plugs the opening fairly quick. if using it, spray at night when its nice and cool out, there will be more wasps in the nest and they wont be as active. The product is available at any garden center.
Thanks for your reply. Is the foam just for plugging, or does it also kill the wasps? We have already applied a foam to block their entry, but they found another way. I'm afraid that if we try blocking again, the wasps may find a hole via the inside of the garage.
the aerosol foam is an insecticide, it blocks up the hole (temporarily) and has a bug killer in it( likely Sevin). I have used it on a hornet nest and just sprayed the outside of the nest (in a shed), the next day, no hornets were alive.
The other thing I was advised to do was to use a torch with red cellophane over it so that you can see what you are doing and not disturb them. Mine was in a bank and I had no light to see. These were what we call European wasps an invader that has only been here about 20 years. Sure has made it's self at home. Liz
any wasp & hornet spray (foam or liquid) will work. spray after dark as they will be resting and you're less likely to get stung. most of the sprays will shoot the stuff at least 10 feet - so there's no need to get close (and in danger of being stung). soak the opening well and try to get the spray directly in - if there is any of the nest wall visible, soak that well also. you may see a few fly out...they'll die quickly enough (just steer clear of them until they do as they'll be angry and ready to attack). the next night, spray again - this time be a bit closer so you can be sure to aim the spray directly into the opening and really give it a good soaking in case there are any stragglers left. is the nest actually IN the wall? or just on it? or in the soil? if it's on the wall or in the soil, after you've sprayed it well and are sure there aren't any of the insects left, remove the nest (others will come along and reuse the living space). if it's actually in the wall, you'll need to plug the entrance up very well.
