If you have a bug zapper up, it's time to take it down.

A University of Delaware study analyzed nearly 14,000 insects killed by zappers over one summer. Mosquitoes accounted for less than 1%. The other 99%? Moths, beetles, midges, fireflies, and other beneficial insects.

It's even worse than it sounds: mosquitoes find you by carbon dioxide, body heat, and skin chemistry. Your zapper is completely invisible to them.

Meanwhile it's running all night massacring the pollination night shift.

@dbattistella Why would anyone keep one of these outdoors? That's terrible. I keep one in the house for flies.

I think this is the study, for reference.

Thanks for the news, and the article.

I too searched and found the same link, but what stood out , amongst other things is that this study is published in 1996. 3 decades ago. While this method has not changed there are likely newer methods, to kill insects, being used.

Wonder if anything has changed ( presence of insects, population of insects, other (ans alternative) methods and their effectiveness.

@ramkay @dbattistella those zappers are cheap, and I still see them a lot.
Anecdotally, over the past few years I've seen a lot more "repellents": chemical or natural things you spray around, or those coils you burn. Hopefully those aren't as bad.

@bovaz @dbattistella

There is a low cost variation of a zapper in use

A light is in some kind of inverted covered lampside

Bugs get close and slip down or fall into a "trap bucket" . They dont die immediately, they are just trapped and eventually die of "being inescapably" trapped.

The trap buckets are cleaned once in a while, while the light also functions as a regular outdoor light.

Dried Dung has been used forever as a smoke based repellent, chemical ones are both lethal & non lethal

@ramkay @bovaz @dbattistella 1996 cannot have been three decades ago 😭
@jawnsy @ramkay @dbattistella I think they meant decaliters. "1996 was three decaliters ago", as in they drank 30 liters of, presumably, water since them. So it's less than a month ago, which sounds about right.
@bovaz @dbattistella @ramkay Thank you, this makes much more sense
@dbattistella It's anecdotal, I know, but when I clean out my small zappers it is 90% mosquitoes. I suppose it also heavily depends on where you are. I live near a creek and the mosquitoes are very much a problem. I have to clean out the zapper about twice a week and it is entirely mosquitoes. I have a healthy honey bee, wasp, and firefly population here.
@dbattistella Yeah I bought one and only used it once because I saw the problem immediately.

@dbattistella Admittedly it's different for indoor use. If I already have mosquitoes inside, running a small zapper with light and closing the door did wonders.

But of course, indoors almost no insects are beneficial to begin with.
@dbattistella One 30-year old study that implies (but does not state) that they were looking at outdoor zappers, in one small, marshy area of Delaware, with a very small sample size is not much of a data point that can be universally applied.
@kittylyst It's definitely true that those traps don't differentiate between species, and that they are rather bad at catching mosquitos. So why kill many more of the animals that would kill mosquitos if you want fewer mosquitos? Just for the satisfying sound of the kill?
@dbattistella
@dasgrueneblatt @dbattistella They seem to do an excellent job of wiping out mosquitos indoors.
@dbattistella mosquitoes are also pollinators
@dbattistella Anecdotal evidence or not, anyone who spends more than 10 minutes observing a zapper will notice that mosquitos are not the only insects it affects.
@dbattistella was this post written by mosquitoes? I don't trust anyone any more
@dbattistella now I'm imagining a couple of bats saying to each other, "let's pop over to Bob's, he always serves those crispy fried moths".
@dbattistella They also are killing pollinators.
@dbattistella If life gives you standing water, pour it out, and dig or set a BIGGER pool of standing water. ADD TADPOLES AND FISH. Enjoy the nightly frog music and fish with healthy mosquito-larvae-boosted fish fat.
@dbattistella we have four in the house. They'll stay. No goddamn place for moths.

@dbattistella I've never had a zapper, but can you provide a link to the study?
