ogatec said:these things are very powerful, no need to have it in the gardn unles there is a pest problem. when all the pests are gone ti should be taken out. i once used one of thesein my house when i first saw them. it cased all sorts of temporary problems for me like muscle weakness & twiching, which went away when i removed the strip. BE CARFUL WITH THESE THINGS. they are a powerful poison& i wouldnt want to be smoking the residue.
that beeing said they work very well when you have an infestation.
