I was rather skeptical of Orange Guard but I try to use chemicals as little as possible. I purchased this product to use on sugar ants and small household ants that were showing up around my cats food bowl. This product kills ant instantly on contact. It has a very strong smell which is rather pleasant in small doses. The downside is the lack of a residual effect. It does not seem to prevent ants from coming back for very long. I suggest you use this spray for immediate control of present insects especially in sensitive areas such as around pet food bowls but you may need something with a more long lasting effect for reoccurring problems.
