About PF Harris: A Legacy of Solving Pest Problems

PF Harris has a long and distinguished history of problem-solving when it comes to pest control. In 1924, just two years after the company's founding, Harris tackled a significant infestation at the Calvin Coolidge White House, which had been overrun by roaches and water bugs for years. 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 had just fought a decisive, winning battle with a horde of cockroaches that had infested the lower regions of the Executive Mansion.

Over the course of the next few months, Harris took his effective pest control solutions to dozens of government buildings, including the Senate Office Building, the Department of Justice, the Supreme Court, and Walter Reed Hospital. Each superintendent of the various buildings was highly satisfied with the results.

Today, PF Harris remains agile 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.

PF Harris is America's oldest EPA-registered pest control company, with more than 55 products designed to treat everything from roaches and bed bugs to scorpions and stink bugs. One of their most effective solutions is the Harris Boric Acid Roach Powder.

Using Harris Boric Acid Roach Powder

To use the powder, shake the container well before opening. Then, using the easy applicator, create a barrier through which cockroaches and other insects must crawl. Puff a light dusting of the 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, ensuring the powder remains effective as long as it stays dry.

The boric acid works by interfering with the roach's digestive system. Additionally, 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 and Prevent Roaches

To eliminate an existing infestation, use liquid insecticides 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. The 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, placed next to baseboards for optimal effectiveness.

To prevent future infestations, remove excess food scraps and limit the availability of water in sites that have been infested with cockroaches. 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.
