Review (4/5): So far, so good
I’ve been using Harris need oil for for about 3 weeks to combat an infestation of box elder bugs. It’s early, but it seems to be helping. The directions say to use it once a week for infestations, but I use it pretty much use it every day. Dish soap (any kind) and water will kill them, but there is no residual effect. I’m hoping the neem oil will add that to the mix, pun intended. The oil hardens, so I put it in a jar of hot tap water and in a few minutes it’s liquid again. The two bottle pack was a good price and it seems to be a quality oil.
