We have roughly the same climate in Sweden where the Swedish Environmental Protection Agency sprays lakes with Bacillus thuringiensis israelensis (Bti) to stop them. The product is VectoBac® Granules from Valent BioSciences, it's super effective. Unfortunately not available at the supermarket :)

      Depends on where people complain enough to convince the Swedish Environmental Protection Agency to deploy it. There are many locations where this is used though (especially towards the north), some rainy summers people are unable to go about their daily lives due to the extreme nuisance.

  The Marin/Sonoma Mosquito & Vector Control District uses BT or at least it did the last time I checked (about 12 years ago).

> not available at the supermarket It's not? Here in the US, hardware stores sell Mosquito Dunks[1] or Mosquito Bits[2], which seems to have the same stuff in it. --- [1] https://summitchemical.com/products/mosquito-dunks/ https://summitchemical.com/products/mosquito-dunks/ [2] https://summitchemical.com/products/mosquito-bits/ https://summitchemical.com/products/mosquito-bits/
