A year ago I installed a mosquito bucket, inoculated with Bacillus thuringiensis, which supposedly kills larvae before they pupate into bastard bloodsuckers. I remained unconvinced.
It turns out that the color of the bucket makes all the difference, as mosquitos, being the tiny demons that they are, like darkness. So when last year’s bucket cracked, I replaced it with a black one.

And behold!

It’s difficult to tell from the photo, but there were larvae (those white grub things). And one was dead. I’ll take that as confirmation that the deathtrap is now finally working!
Small victories.
