Insects invading your corner of the world? Whatever insect you're fighting, Black Flag products are dedicated to providing the tools you need to regain control. With formulas that act fast and never back down, Black Flag insect controls have been arming homeowners in the battle against invading bugs for more years than any other brand. Houseflies complete their life cycle to adult within just a couple of weeks. They get in through open windows, doors, cracks and crevices, and they stay because they can?t find their way out - and because the sugary foods they love are often abundant on our countertops. They can carry diseases that can then be transmitted to humans when they touch our food. Black Flag Fly Paper is a simple way to control houseflies, mosquitoes and other flying insects. The trap provides long-lasting protection after opening. Once flies land, they never leave. Just unroll the sticky paper using a twirling motion and hang anywhere flying insects are a problem in the home or around the porch, patio or garden. If the trap is cold, bring it to room temperature before using. Hang it away from sunshine. Simply wrap in newspaper and replace when the fly paper is full. This trap can also be used to control gypsy moths. Wrap the tree trunk at a height of approximately 4 ft. As the gypsy moth caterpillar makes its way up the tree to reach the leaves, contact with the sticky surface will prevent gypsy moth caterpillars from crawling further.
