Hang these traps in the immediate area of pest infestation. For trapping out, use 1 trap per 25-50 sq ft. For monitoring, fewer traps are required. The package includes twist ties and instructions. Each package contains five 4 x 7 cards.
I had an infestation of white flies on some rhubarb plants. I hung two traps by the plantsand within tree days the white flies were gone (trapped on the cards) and all evidence of white flies has completely disappeared.Review by Nancy (on 6/4/12)
