It works very well for bugs like flies, fleas, spiders, and such. However this product does nothing to eradicate sugar ants. We have mounds and mounds of them outside our foundation in the sandy soil and in my potted plants and this did nothing to even slow them down. Otherwise I use this as a perimeter spray up high (we have free range chickens) and also perimeter inside the house in spring and fall. I coordinate to where we will be gone for extended time to account for any fumes after applying inside. works great for price-real value compared to Ortho and I think it actually works better!
