Wierdly long AI-esque video.

Place dark color bucket, fill with water

Add handfuls of grass clippings.
Add a scoop of mosquito bits ( aka, BTI. Bacillus thuringiensis subspecies israelensis.)

It's a naturally occurring soil bacterium. When mosquito or gnat larvae eat it, proteins (crystal toxins) produced by the bacterium destroy their gut lining and kill them within a day or two.

All mosquitos that bite you are born near by, so, add grass and BTI to all standing water once every few weeks.

There are slow release BTI donuts you can use too, last longer.
