Cockroaches

The German cockroach is by far the most important and usually the most common of the cockroaches. Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. German cockroaches have the potential to transmit disease, and associated pathogens, and may potentially trigger allergic reactions. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Medical studies have shown that cockroach allergens cause lots of allergic reactions, especially in children. They were even shown to cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.

German cockroaches can be found throughout structures but show a preference for warm and humid places. They are usually found in kitchens and secondarily in bathrooms, but infestations often occur in rooms where people eat and drink. German cockroaches prefer to live close to sources of food and water, hence their affinity for residential and commercial kitchen environments. These roaches prefer to live in cracks and crevices near food sources and spend 75% of their time in such harborages.

Graduate cockroach treatments come with a full year's warranty when a complete building is treated. We recommend the use of insect bait materials for the treatment of cockroaches. They have a number of advantages over traditional spray materials when applied by an experienced, certified professional. These non-repellent, odorless materials attract cockroaches rather than scatter them to other areas. The delayed action of the active ingredient allows the foraging adults to bring the material back to nesting areas and the immature cockroaches' will also be affected and die.
