Wandering in the countryside one can sometimes encounter some traps made of a plastic bottle filled with some liquid (usually beer or a sugar solution) in which hornets and other insects lie dead. Some of these traps may be part of a sort of network to verify the possible presence of invasive wasps.…

Many traps associated with a scientific protocol will likely have a small tag or explainer with contact info on them or perhaps research permit info. In most cases, it’s unlikely that a few traps are going to have a large population level impact, so I wouldn’t bother the traps. If there is a tag, y…

Studies where they catch lots of different insects hopefully also save everything that they catch (you can keep stuff like this pickled in alcohol or formalin) so that even if they are only interested in say screening for one invasive species, other researchers could use the samples later to survey …

no word about whether “the countryside” is referring to wild spaces, or people’s living spaces, or what. but such traps are fairly common in the US where people want to keep yellowjackets away from their picnics, yard spaces, etc. people with severe allergies to bees/wasps are going to be more likel…

I’m not allergic but we put out traps specifically for yellowjackets (Vespula pensylvanica) to keep them from nesting in our garden. We check them daily and release any other insects that get caught, even paper wasps, but that rarely happens. I’m sure others are not as selective though. Most of the …

We only trap the specific wasps that are aggressive. Even though I’m not allergic, the stings are very painful and cause a large swelling that itches for several days. They would even get into our house and sting us. We still have lots of paper wasps and mud daubers which are very docile. There are …

Even if you feel attacked, such language isn’t acceptable on this forum, it’s in the rules and common sense of having small children on here should stop you from using it.

If you don’t mind me asking, why do you trap wasps in your garden if you’re not allergic? They are very helpful in pollination and killing of caterpillars and other critters that would like to eat your plants.
