What size house will one foil package of Demon WP do and how often should it be sprayed?
Each Demon WP envelope comes with 4 water soluble packets, enough to make up to 4 gallons of diluted solution. Most homeowners use 1 gallon of diluted solution or less indoors and about 2 gallons outdoors per application . Depending on the insect you are trying to eliminate, you can spray once every 1-3 months. Please read the Demon WP product label to learn specific usage rates for the insect you are trying to eliminate.
