    Is hot water truly necessary? Is its purpose just to mix the soap and water better, or does the mixture need to be hot in order to kill instantly? Because I just tried this, but with room temperature water, and it still crawled around for a while and I’m not sure it died.

    1. Dinesh Kumar

      Hey Candace, hot water is just for the proper mixing of soap and water. because soapy water clogs their spores to kill them. Sometimes home remedies don’t work because we change the concentration of the materials or mistake happened in the application process.

    I also waited till the temperature dropped below 40F so they’d be relatively inactive. Before reading this, I used cold soapy water on them with rational that hotter water might warm them up and make them attack me! Anyhow, with cold temp outside, I was easily able to scrap off about 5 gallons of nest that had grown under my deck and totally saturate the wasps with soap solution. The larger pieces of nests with may of the wasps I then put into 5 gallon plastic bucket and sealed the lid for trash disposal.

    Can You leave a bowl of water and soap to attract them away from pool side? I just got a pool never had any wasps before and noticed the like the muddy water Thanks

    1. Dinesh Kumar

      I don’t think this will help.

    does soapy water also kill other types of wasps, like horn tailed wasps?

    1. Dinesh Kumar

      Yes, it also works on other types.

    If i use the water hose spray bottle do i just make the soap solution a bit more soapy since the attachments are usually used with a concentrate. I have a nest under an eave I cannot reach and don’t want to get close to the wasps anyway. I’m going to wait until evening when they are less active (hopefully).

    I use a large drinking glass. Fill 3/4 with water, a squirt of dawn dish soap and fling the concoction at the nest. Spraying tends to miss a few, a big splash from the glass gets em all.

    wait for the sun to go down and I won’t fly away from their nests beings the sun warms them up so that they can fly so at night would be the best time to attack their nest

    I did this on what I think we’re hornets. Worked.


    Just tried it.
    Worked instantly.
    Receipe-1/3 kitchen size bottle of dawn and 1 gallon of hot water in a garden sprayer. It flushed 2 hornets that I could not even see and they died quickly.
    The way i figure it work for about .73 cents per gallon of solution and it also makes your patio smell like green apples…nice. Choose your scent.

    We are building a patio cover and the smell of the new pine and other woods was attracting them like I have never seen. I sprayed the entire structure.

    You might consider using a pump-up garden sprayer to spray the soap solution. Some have an adjustable nozzle and will shoot a continuous stream up to 12 feet. Test any delivery method before using it on a net.
