that explains. I was always wondering why in Siberia (where i worked for 2 summers back then at university times) coming out from house with freshly applied DEET you're getting covered with mosquitos - i was attributing that to the especial ferociousness of the mosquitos there - yet it sounds like the smell of DEET for them in those towns may have become like a BBQ smell for us :)

Damn, were you working at Tselinoyarsk?

I hope these mosquitoes were not released in the wild. The simple answer would be to add a natural strongly repellent gentle oil to the DEET spray.

And remove the DEET from it, apparently… at least until it loses its appetitive charge.

Until, of course, they learn to like the replacement oil. At which point, break back out the DEET!

Spray made from lemon eucalyptus works[1]. Not as well as DEET, but it works. [1] https://www.consumerreports.org/health/insect-repellent/oil-...

I don’t understand why sharing an objective study with good news would be downvoted, someone please explain?

I’m not saying you have to use it; it’s good news for people who have concerns about other chemicals. It works—less effectively, but it works.

“Repellants containing (..) oil of lemon eucalyptus have also been found to be effective.”[1]

I have seen the same behavior on this site. Insightful information gets downvoted to -2, and useless comments that merely "feel good" get upvoted to +8.

I think the theory is that each post identifies with a certain topic, e.g. DEET, which identifies with a cultish subset of users surrounding that topic. There is no broad academic curiosity among the cult's members, and they suppress all competing topics as to them they represent other cults.

So maybe the solution is to apply DEET to a bug zapper

It was fun, but not a bad idea. Are there mosquito mousetraps, or mosquitotraps?

Could this already be happening out in the wild?

I use a lot of bug spray and I am still swarmed sometimes.

As I understand it, DEET just prevents biting as they don't like the taste of it, and they taste with their feet. Thus, it doesn't do much to prevent initial attraction.

Edit: thought I'd include a link to a study about this as it's not well known. https://www.cell.com/current-biology/fulltext/S0960-9822(19)...

Yes, they are mostly attracted to CO2 I think. So some traps that burn propane to attract them. Others I've seen are basically a screen over a fan with a block of dry ice. They use those to collect for like an hour then weigh the mosquitos and test for diseases in a swamp.

I believe DEET interferes with their ability to locate prey actually.

There are no natural oils that have been proven to stay effective, or are effective as DEET.

Go ahead, hose yourself down with Lemon oil, citronella, oil, or lemon eucalyptus oil. They simply do not work.
