Question about Hornets
 

I have a new home in Dabney with Vinyl siding. I have seen hornets disappear behind the vinyl siding and I know they're building nests in there. Clever hornets but I'm not too happy about it especially since I'm allergic. Is there a clever way to spray behind there to kill them and their nests? Because spraying the outside of the vinyl doesn't do anything - they are completely protected. And will bug killer effect the waterproofing behind the vinyl? Thank you in advance.

Call a pro.

So you won't get stung!

The other day we decided to trim our bushes/hedges and were very surprised when swarms of very aggressive and hard biting small hornets attacked us. They have nests in at least three of the plants and forced us to stop our yard work. We usually do that task in the spring/fall and have never had this problem, wondering if it’s a summer thing? I immediately put in a call to our pest control company and our guy is coming out later this week.

yeah, i agree. leave it to them-i'm sure they have ways of removing it that won't harm the home or you, :ho:

yes, if they are going in and out of the vinyl..........they have a home made already.

Some of your vinyl may need to be removed to find the home(s) and destroyed.

Sure they’re not mud dauber mud wasps? I just seal crack with clear caulk.

From goggle

“The major difference between wasp and hornets is size and colour. Wasps (left) are about one- third inch (one centimeter) to one inch (two and one-half centimeters) long. Hornets (right) are larger. Wasps have black and yellow rings, while hornets have black and white rings”

Another vote for calling a pro.

If you want to do it yourself, you can buy a can of foam (polyurethane?)with a large diameter straw. This will fill the opening more completely than caulk. Depending upon the shape and size of the opening, caulking doesn’t always work.

Check with the Ace hardware store in Wildwood. They seem to have solutions for most problems.

Please make sure it is “minimally expanding” foam or it will blow out the siding. Even then, be careful.

The million dollar question is how big of a nest. A small one I would feel comfortable spraying hornet killer thru the slot in the siding. Repeat if necessary, then caulk the hole. Spray at night when the bugs are inside.
Hornets bite, not sting. Shouldn’t be allergic to a bite? Tho pain and swelling will happen. A large nest, call a pro.

Call someone who knows what they’re doing.

Hornets are nasty, call a pro !

Hornets do not bite, they sting.

Oh they ARE mud wasps!!! Thank you, never seen one of those before.

Yes, I think this is the max time of the year for hornets. I try to keep spray cans close by so that I can hit them in the air as they are finding their way toward the siding and their nests inside.

Mud dauber’s are very docile rarely sting. Not like the pit bull cousin’s the yellow jacket. If have any bushes that you have tampered with in while be careful. I watch my bushes see it any yellow jackets are going in them. Yellow jacket look for any excuses to attack and sting.

You could just seal crack off with clear silicone so they can’t get in.

Hornets? More like wasps or mud daubers. Hornets commonly nest in ground. Or make big football looking paper nests? Wasps make the round honeycomb flat looking nest except the mud dauber makes mud hut you see in your garage or front porch stuck to wall or something. My car sets in garage lot, had window down for week and mud dauber made nest on my back seat at top. I kept seeing fine dirt on seat noticed it when I looked up.

Probably yellowjackets.


“ Yellowjackets are more aggressive than other stinging insects such as wasps, hornets, mud daubers or bees. Yellowjackets can both sting and bite -- they will often bite to get a better grip to jab their stinger in. Since they don't lose their stinger, they can sting numerous times, and will do so unprovoked. “

I understand CJDR dealers are also struggling to get rid of their Hornet problem.

Urgent, call a bee removal company. They remove the nest & give you a 1 yr protection policy, which means the company will return if the wasps return. My neighbor sprayed one end of the nest. The bees kept building onto the other end. The nest was 5ft long. They also must check inside the attic.

" How many mud daubers per nest?
Mud Daubers
one individual
Typically there is only one individual in each nest or burrow. If the nest is constructed of mud, this is one of several species of mud dauber. Mud daubers are solitary wasps that construct small nests of mud on the sides of buildings, rafters of open structures, bridges and similar sites. “

OP said they were mud dauber’s very different from bees.

“ bee?
Bees tend to be 'hairy' to allow pollen to be gathered more easily whilst wasps tend to be bald and shiny in appearance. Honey bees are social insects and live in a nest which may contain several thousand workers. Unlike wasps and bumble bees, the honey bee's nest survives for many years. “

That’s going to be problem, those hornets have no sting. Who wants rebadged fiat? :22yikes:

Rocksnap is correct, if you’re afraid of getting stung do it at night or pay someone to do it for you.

They are most likely just Mud Bugs not Hornets…. Easy to spray and get rid of them.

Had pest control to take out a Wasp nest in my house roof here in UK a couple of hours ago.
Without protective gear, no way will I tackle the little £%$^&!$.
Operative wore the appropriate protection while pumping in the powder, and boy, were the buzzers peed off!

I have always had a yearly contract with an exterminator. In my experience preventing or getting to a problem early with insects is so important. Especially in Florida. Would highly recommend you call a professional.

right? Hornets don’t bite they nasty sting. OP said they were mud daubers which only build solitary single nest for larva.

How much mud can a mud dauber daub when a mud dauber does daub mud?

Question. Regardless of what kind of bugs they are, do you really want to (hopefully) seal them inside the wall?

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.
