In Legal Cannabis History 101 classes, 2015 will always be remembered as the year legal marijuana recognized its pesky pesticide problem.

But some cannabis growers are getting creative — using what are known as “beneficial bugs” to do battle with the bad bugs that can take down an entire crop.
“We use nematodes, the little beneficial bugs that we put in the soil, so any soil-born insects, we use those little guys to attack those,” Honest Marijuana founder Anthony Franciosi told Cannabist editor-in-chief Ricardo Baca on The Cannabist Show recently. “And then we use beneficial predator bugs like swirski mites and californicus mites, which we use in small doses here and there throughout the garden in little breeder packs.
“The idea is that we have enough little good guys there that we’ll prevent an infestation.”
