The mosquito bucket of doom is a population control mechanism where you dissolve some Bti (Bacillus thuringiensis israelensis) into a bucket and allow the mosquitoes to lay eggs in these buckets. The larvae then feed on Bti and die.

I tried this method, and it has been unexpectedly effective.

Background

I live in a really wooded area. It's not swampy, but we have a lot of mosquitoes.

I didn’t take the baseline measurements in the previous years, but on hot months like June, July, August, and partially September, it would be quite literally impossible to spend any time out in the yard – in the morning, while the sun is not super strong yet, you get bitten by dozens upon dozens of mosquitoes. Then the sun is super strong and it's impossible to be outside. Then, in the afternoon or, god forbid, evening, there are swarms and swarms of mosquitoes, which make it impossible to be out and about.

According to my own guess, I would, at all times, be surrounded by at least 20 or 30 mosquitoes. Killing 30 mosquitoes per hour was not uncommon. That's one mosquito every two minutes!
