“I just put it on the day I got it and I slowly and seeing a big difference until I don't see any certain pests around that irritate my skin and stuff I will gladly let you know I haven't seen any spiders that's for a big plus cuz my grandbaby is allergic I did have a case of bed bugs but I barely see any one here one there it's like they're slowly dying out when I don't see any anything at all for at least 3 days I will give back another review but until then so far so good”
