My $30 rain barrel turned into a mosquito nursery in 3 weeks
Bought a cheap 50-gallon barrel off Facebook Marketplace and set it up under my downspout in Portland. I forgot to cover the top, and by week 3 it was a buzzing larvae soup. Anyone else run into this, or do you use a screen or add some kind of treatment to keep it clean?
Oh man, my buddy had the exact same thing happen with his rain barrel in Seattle! He left it open for like two weeks and it turned into this gross soup of wigglers, he said it was nasty. What he ended up doing was cutting a piece of window screen and rubber banding it over the top, plus he drops in one of those mosquito dunk things every month or so. Seems to have worked for him so far, but your mileage may vary depending on how hot it gets where you are. Cheap fix though, way better than dumping the whole thing out every few weeks.
