Problem solving has a long heritage at PF Harris. In 1924, two years after its founding, the company tackled the Calvin Coolidge White House, which had been overrun for years by roaches and water bugs. Harris’s product was so successful in eliminating the scourge that he was described on the front page of the Washington Times as a "vermin slayer" who has just fought a decisive, winning battle with a horde of cockroaches which infested the lower regions of the Executive Mansion. Over the course of the next few months Harris took “his final feast” to dozens of government buildings, including the Senate Office Building, the Department of Justice, the Supreme Court and Walter Reed Hospital. Success followed success: Each superintendent of the various buildings was highly satisfied with the results. The company today stays nimble enough to respond to changing market demands, leading the way in the development of numerous products, including natural insect repellents like Swamp Gator and Swamp Gnat which repel biting insects without using deet. Beyond the products it sells, Harris helps customers find easy and economical solutions to pest problems through helpful labeling, instructive videos and personal advice. It’s a brand with a reliable past and an innovative future. PF Harris is America’s oldest EPA-registered company. With more than 55 products, the company provides solutions to treat everything from roaches and bed bugs to scorpions and stink bugs.

Shake well before opening. Using the easy applicator, create a barrier through which cockroaches and other insects must crawl. Puff a light dusting of powder in areas such as behind refrigerators, along baseboards and in cracks and crevices where roaches have been seen. The powder contains a lure that roaches will seek out. Take measures to ensure that the powder is kept dry in order to remain effective.  Boric Acid works by interfering with the roach's digestive system. In addition, the powder will cling to the outside of the roach, helping to kill other roaches when the affected roach returns to the colony. The powder is fast acting; insects coming into contact with the boric acid will die within 72 hours. 

Eliminate Liquid insecticides can be used to treat in and around the infested harborages in kitchens and bathrooms. Treat along and behind baseboards and into cracks and crevices on counters as well as under sinks. Use boric acid roach tablets in hard to reach areas under sinks, and behind refrigerators and other kitchen appliances. Roach powder can also be used behind baseboards and in locations not easily treated with liquid insecticide. Sticky traps can be used to control infestations. Place these traps next to baseboards for optimal effectiveness. Prevent Removing excess food scraps and limiting the availability of water in sites that are infested with cockroaches will help control these pests. Be sure to clean up spills and crumbs right away and avoid leaving food out in the open for extended periods. Seal any cracks and openings with caulk.
