he said "hot shot pest strip from home depot, but it is chemical."
But it really works. I put one in my box early in the grow, then take it out when I flower. Some people leave it in all the time or until the last month of flower.
I moved my box and cleaned it out, placed a Hot Shot No Pest Strip in the middle. The next day I found 1 dead bug, no more for the rest of the grow.
Just $ 0.02
