question to those who have used the "no pest strips"

i have noticed a spider mite problem developing in my box. after looking around i came across these no pest strips that you just hang and it kills any bug. people on this forum have said they have worked.

so i bought one and have hung it, but here is my question.. it says that the strip is good for 900-1200 cu. ft. my box is only 75 cu ft. so should i leave the door to the box open? will this be too much fumes for my box,or is this not a problem at all?

thanks in advance

Not a problem at all. Leave it in for 7 days and you should be fine. Did fido bring them into your garden maybe? I never let pets in the garden.

no, not sure what it might have been. i brought some 2x4's into my box that i had sitting outside for a while, so maybe they hitchhiked on those. thanks for the answer man, i appreciate it.
