Or just wait till dauber leaves then seal it.


Everything ever want to know about dirt/mud daubers.

Mud Daubers

The following is what I found on line. Never hear of wasp dust.

The magic secret, simply put, is to use the wasp killer dust. There are a few options, one is called Delta Dust. Another is made by Bayer and called Tempo Dust.

So, to get rid of yellow jacket wasps under vinyl siding you want to make sure this is in every crack and crevice in your house’s exterior wall. The more cracks you can find, the better. Fill in any gaps with the dust, which you can buy online from Amazon with no professional credentials.. That will seal off the entrances in a way that prevents the wasps from coming in. The dust repels the wasps and they cannot survive if the dust gets on their feed and on their exoskeleton.

DO NOT use spray foam to seal any cracks. Wasps can dig right through the spray foam and you will ruin whatever surfaces you are spraying on.

One thing to keep in mind though: I said before that wasp killers are also cockroach killers… which means they’re bad for pets like dogs, cats and birds if eaten or somehow ingested by them. But I only mention that now because it’s something to keep in mind, not because you have to worry about it.

Spray some Seven Dust in the hole , they will carry it back to the nest and it should kill them. Worked for us.

I understand what people are trying to say, why take the chance! Even if someone says they’re flies.

We have red wasps. Hubby uses a spray /on/ them directly when he sees them flying near him. I ignore them as long as they're not inside the house. The only time the red wasps get aggressive is if you threaten their nest. They fly around me when I'm weeding my flower bed.

I think those are what have been nesting in some of our hedges and bushes. They got very aggressive when we were doing our trimming and gave my wife a few very painful stings.

To many Hornet experts bite or sting who cares it hurts. Do what they want to get rid of them. Bite or Sting do it at night or get someone there. I’m not here to debate it just answer a question that we were asked!

Sorry I try to stop misinformation when I come across it. Some can’t tell hornet, wasp, from horse fly.
