Questions & answers about wasp nests
Fran asked:
Hello Paul. We have our exterminator waiting on an answer from us as to whether or not we want him to treat the hornet nest . Will we have an odor in there from the dead hornets & larvae? It\'s located in the eave beside our kitchen & there is no plaster board in between. Only insulation. We\'re afraid of getting an odor in our kitchen. Thanks
Paul Sweet replied:
Hi Fran, your exterminator should advise you on what you should or should not expect. I take it he is a professional pest controller? Anyway, you should not experience any odour from dead wasps or hornets, but sometimes the nest can become damp due to insect prey being dropped at the bottom of the nest and can happen regardless if the nest is treated or not. This dampness can smell musty for a while.
Fran asked:
Hi Paul. Thanks for the answer. I have another question. If we just leave the hornets nest alone will everything in it leave after cold weather? We don\'t want one of the queens hibernating in it and having another swarm of hornets in it next year. Thanks
Paul Sweet replied:
Hi Fran, if you leave the nest alone, it will mature and release new queens. These may or may not hibernate in your locality and decide to build a new nest next year. I cannot tell you if this will happen or not as no one can predict this, it is pot luck if you get another nest next year. All social wasps make a new nest each year. http://www.hampshire-waspcontrol.co.uk/wasp-lifecycle.php Hope this helps P.S wasps do not swarm, only honey bees.
Fran asked:
Hello. We have European hornets that are only posing a problem at night. We can\'t sit on the porch without them showing up. Even with the porch light off. Will they return to the nest next year? I\'ve heard contradictory answers on that. Should we call the exterminator or just let the nest die off in winter? The nest is enclosed \"inside\" our overhanging eave. After winter should we clean out the nest, which would require some construction work ? Or, just leave it & close up the hole they are entering through? Will there be any hibernating queens left in it? If so, will they make their new colony there? Thanks
Paul Sweet replied:
Hi Fran, sorry for the late reply, but we have been very busy. If they are bothering you, get someone to sort it out for you. If you deal with the nest now, it will not have produced new queens yet. Hornets are always a bit behind wasps. No need to remove the nest after treatment unless the nest is located on plasterboard and is making the plasterboard damp. Just seal it up and forget it.
