I'd suggest not using any chemicals, washes, sprays or bullshit, you can Dry your bud in water and remove all the bugs, and anything left over, I am doing it this way as I had the same problem, you also increase the THC and you can dry it in 7 days vs taking weeks, you do lose a bit more weight though, but I'm currently doing 3 plants this way, it's suppose to give if the best taste also, If you want to know just reply or just google it. called Water Curing
