    I'm going to try the seven dust first since I do have a ton of that on hand as we use it in the garden.

    If it helps at all as to the confusion on Cicada killers/ground hornets; last year they went into a hole in the brick and into the attic which I stopped up last fall with silicon.

    MY BAD, I didn't clink on the Picture and only assumed the right ID was a Ground Hornet. But with a larger infestation they can and will sting. While they might not be as dangerous as Ground Hornets, I would still want them gone.

    Cicada holes look like someone drilled a hole in the ground usually lots of seperate holes one for each larvae. But any dust like tempo connect a length of poly hose that goes over the tip, you can att the hose to a length of dowel to direct the end of the hose. Squirt some in the hole at night, hold your breath they can p/u on the CO2. When they beat their wings to cool the nest the insecticide will move they will all die w in days.

    I put the seven out last night so we will see.

    I'm starting to lean more toward Cicada killers and the reason I say this is because the amount of holes humble1 is refering too, there are at least 20 now in the back and it don't seem like there are more then one going into each hole???

    Any thoughts?

    While putting the seven out last night I could get close enough to hear it, sounds like a dirt dobber backing mud :laugh:

    The first pic is of a cicada killer. They've been active the last few weeks here, and are considered beneficials by many books and manuals. They don't live in colonies and are very territorial from what I've read. I walk past 4 or 5 of them every morning the past week or so to get the paper and I walk right through. I have seen them do some damage in the summer months with all the holes, but that usually fills back in quickly early fall.

    These critters are not going to hurt you. They in fact are cicada killers. The reason I know is I'm highly allergic to stings. I ran across these a couple of years ago. Took one to friend of mine who is exterminator, and he stated, they are not aggressive to humans. I have been working in a yard over the past 2 weeks that has these guys flying around everywhere. We even got to see one take down a cicada, kill it and fly off with it( very cool).

    We'll I haven't seen one take down a cicada however I have seen them today on the ground dragging the cicada's into the hole so they are in fact cicada killers. I've been working on that side of the yard all morning and had the chance to experience them at work.

    Just watching them in the grass dragging the cicada into the hole is ahhhh wicked to say the least.

    The first pic is plain as the nose on one's face, a cicada killer. The second pic is exactly what one of their nests\holes looks like.

    I wasn't sure if they were aggressive either but was messing with one coming out of its den, flew around me but never came close to landing on me.

    I'll try to take a pic of an infield that has probably at least 100 holes in it. So I wouldn't say they don't colonize, as I could see a half dozen at one time.

    The cicada-killer wasps that are digging are not typically aggressive to the point of stinging someone. This is a seasonal thing and the wasps are the females digging a hole to bury the dead cicada with a single wasp egg inside. I was seeing them all over today, and while they will approach a person, I've never known this particular wasp to actually sting a person.
