The product label for the Endzone Insecticide Sticker has complete instructions with a picture diagram but states the following:
Stickers have an adhesive coating on one side and a plastic cover on the other.
With dry hands remove cover from the adhesive coating side first. Please sticker in desired location. Once sticker is adhered, remove the plastic cover to expose the attractive coating.
EndZone Insecticide Sticker can only be applied to windows. It may strip the dry wall.
Endzone Stickers can be used near light sources, on windows, and other surfaces where these flies congregate such as kitchen areas. Be sure to place the stickers in areas where they will not get wet and keep them dry after application.How many stickers you use will be based on the area and size of where the flies are found. The use of one sticker per 1000 cubic feet of space is the recommendation. More stickers are used for heavy infestations. Place one sticker per window for quicker results or in rooms with high infestations.
