Works good on palmetto bugs

Product received earlier then promised! Definitely would recommend to others! Works like a charm.. In the first few days after application all palmetto bug and any other bugs were all found lying upside down or practically dead. Does leave a residue that may mess up wood finishes.. so becareful!
