Smoky Brown Cockroach

SMOKY BROWN COCKROACH - Some of their more common names are wood roach, brown roach, black roach, tree roach, palmetto bug, large roach, roach beetle, and yard bug. These are primarily an outside roach but they will move indoors in search of food and water. These are a large roach growing to about 1 to 1.25 inches so they are a little smaller than the American. You will usually find these roaches outside in mulch and ground cover where it is moist and dark and in trees if they have openings. When they come indoors you will find them in attics mostly, also in storage rooms and scattered throughout sometimes. This is mostly a southern pest but can be anywhere due to shipping of materials.

BIOLOGY- The adults are dark brown to black in color. They are good fliers with wings that are well developed and extend to the tip of their body. Their egg cases are dark brown and have about 24 eggs in them that will hatch in one to two months. The young will reach adulthood in 10-12 months. They will feed on a variety of foods but prefer decaying organic matter. They can carry organisms that cause disease because of the areas they inhabit like drains and garbage cans. Then when they contact our foods and preparation surfaces they deposit these organisms on to them.

CONTROL - To control these roaches one of the most important steps is to improve sanitation. Now because these are mostly outdoor roaches we are referring more to cleaning up outdoor debris, mulch, water leaks or wet areas, and making sure trees are not touching or overhanging the house from which they can fly or climb onto your place. Also try to caulk and seal up any crack or entry way for them to enter your home. Remember, this helps but will not guarantee extermination or prevent an infestation. For outdoor treatments you can use granular insecticides to put a 4-10 foot perimeter around the structure such as Talstar EZ or PL Granular Insecticide, and baits such as Maxforce Granular Bait, and Niban Granular Bait. You can also use liquid concentrate residuals to spray a perimeter around your structure such as Onslaught and Demand which are microencapsulated for extra long residual, also Suspend SC, Talstar Pro, EcoPCO WP-X, and Evercide are good choices too. Use these to put a 4-10 foot perimeter around your house and make sure you hit any and all entry points such as pipes and cables going into the house, and around windows. Another good place to hit is to spray around and 3 feet up any trees that are close to the structure. Once they move in then you should focus on the inside and how they got in. Control can be achieved using various baits such as Maxforce FC Roach Gel Bait, DuPont Advion Roach Gel Bait, or Niban FG and Maxforce Granular baits. Baits work well because of the transfer effect. Roaches consume the bait and pass it to other roaches so you get a more of a kill. You can use residual liquid insecticides such as Onslaught, Evercide, Suspend SC, Demand CS, Demon WP, and dusts such as Borid Dust or Delta Dust, crack and crevice aerosols such as Cy-Kick, Invader, Intruder, and PT-565 Plus XLO. You can also use environmentally friendly and safer pesticides such as EcoPCO WP-X, EcoPCO AR-X, EcoPCO ACU, EcoEXEMPT Granules, and EcoEXEMPT D Dust. One of the most important things to use is an Insect Growth Regulator called Gentrol. This is basically birth control for roaches; they will grow up to adulthood but will be unable to reproduce thus breaking their life cycle. It is very simple to use, you mix the concentrate with water and the residual insecticide in your sprayer, or if you select Point Source then you break the ampule and place the disc where it is needed. The best approach for an infestation is to use a combination of products such as a granule, bait product, an aerosol, a dust for voids, and a residual liquid, depending on whether the infestation is indoors or out.

Geographic Location(s): Mostly in the south but can be anywhere due to shipping.
