Hey opie i have a huge question for you. I am looking for these strips and im in canada, Ive asked around and they say they dont allow them here so i found something else from VAPONA called No pest strips but they say its for killing flying insects. i dont understand how it could be for only flying insects when the active ingredient is 20% and thats the same percentage as hot shots has. Do you think these other ones will stil work please reply because im thinking about going to the states just to pick these things up.
