Questions and Answers about wasp nests


Daryl M. asked: ask a question about wasps


Hi Paul, I'm from Pa.I have two questions. 1. Why is it when I mow my lawn, the hornets will not bother me, but when I look directly at the nest, they will attack? 2. I recently removed the hornets nest and opened it up. I found a couple of different sized bees hibernating inside of it. One was very small and is still alive and crawling around in a glass jar. The bigger ones seem like they are still hibernating. What do I have here?

Paul Sweet replied: Hi Daryl, Very often Hornets are not that aggressive and in my experience they are no where near as bad as normal wasps. You can get away with mowing your lawn and they won’t bother you. But if you approach their nest or interfere with it in any way then this could provoke a defensive response.
I am not sure what the bees are without seeing them and I am also unsure of the different types of bees that you guys get over in the states. They could be some sort of solitary bees that just happen to have chosen your hornet nest to hibernate in. Do a google image search and see if you can identify what they are.
Regards
Paul Sweet

Steve T. asked: ask a question about wasps


I live in Pennsylvania. Now that all the leaves have fallen from the trees I can see a wasps nest the size of a basketball hanging from a branch - much higher than I can reach. Will this nest be active next year? Or should I not worry about taking the nest down?

Paul Sweet replied: Hi Steve, the nest will not be active next year. If you cannot see any wasps coming to and from the nest now, it has already died it is safe to remove. Or just leave it there, it will degrade over the winter and will drop off on it's own.
Wasps always build a brand new nest every year.
I hope this helps.

when will they die

Paul Sweet replied: Hi there, if you are asking how long after a nest is treated does it take for the wasps to die off? We normally advise customers that all the wasps will be dead by the end of the day. In reality it usually takes an hour or two for all the wasps to return to the nest and come in contact with the insecticide, as soon as this happens the individual wasps are history. Occasionally one or two wasps do not make it back to the nest that day for one reason or another and arrive back at the nest the next morning, but they very quickly enter the nest and the insecticide will get them.

If you are referring to wasps or hornets in general, they normally start to die off when the frosts arrive, but there are no hard and fast rules, so we cannot predict exactly when there will be no more wasps this year! The nests we are treating at the moment are still very active and very much alive.
A couple of years ago I treated a nest one week before Christmas. It was still active!
