These pests are occasional or potential nuisances, causing harm by a combination of their populations, feeding or reproductive habits. These pests need only moderate control. The scientific name of is followed by the common name of each pest as is the format of these pages.
Black carpet beetle
The black carpet beetle (Attagenus unicolor) is a fabric-destroying insect, measuring ⅛ inch. This insect feeds on carpet material, as its name implies, as well as clothing and grains.
Management of the black carpet beetle is accomplished by applying residual sprays (spot treatment) as well as pheromones around the foundation of structures.
The clover mite (Bryobia praetiosa), with egg, nymph, and adult stages, undergoes incomplete metamorphosis, feeding on plant matter. This pest is harmless, doesn't bite, and is a nuisance because of its large population.
Considering that this pest enters from the outdoors, successful management centers around exclusion techniques, including the use of an 18-24 inch wide, plant-free strip along the perimeter of a structure. This discourages from using plants as a bridge to the indoors. The application of directed pesticides is also effective against clover mites.
Earwigs are found in the order Dermaptera under in family Forficulidae. These insets are ½ inch long and are so named because of their wings, which when unfolded, appear as a human ear. These insects are omnivorous.
These pests are innocuous, thus chemical control is not necessary, however, insecticides can be used directly outdoors for problem populations.
The webbing moth (Tineola bisselliella) is approximately ¼ inch long. The adult is non-feeding, however, the larvae cause damage to clothing and waste grains during their feeding habits.
The casemaking cloth moth (Tinea pellionella), which is the most common in Georgia, can be differentiated from the webbing moth by prominent spots along with its wings. This moth measures nearly ⅖ inch wide with wings extended. Like the webbing moth, the casemaking cloth moth larvae damage clothes, carpet, and upholstery with its feeding habits.
Cultural and mechanical techniques include dry cleaning and vacuuming, which dislodge eggs and larvae.
Mothballs are effective, along with insecticides to control moth populations.
Booklice or barkflies
Booklice are also called barkflies and can be found outside or inside the home.
Booklice (order Psocoptera) are very minuscule at less than ⅒ inch, called also psocids and grain mites, which feed on mold and need a high protein diet to build large populations. This is the basis of their harm as pests.
Infestations of booklice are treated with directed sprays and aerosols, while cultural controls include removing moisture and food sources, which have proven to be effective.
Silverfish and Firebrats
Silverfish (Lepisma saccharinat), which inhabit cool, humid, and dark places, feed on stored grains and paper. They are easily recognizable by three bristles on the posterior end and by their shiny appearance. These pests measure ½ to ¾ inch long.
Firebrats (Thermobia domestica) are similar in appearance to silverfish but these pests are less iridescent and measure just at ½ inch long.
Cultural controls of this pest involve the disposal of paper products and wasted food. Eliminating humidity and moisture are also effective.
Chemical control to cracks and crevices is effective, especially the use of insecticides, dusts, and baits.
Millipedes and Centipedes
Millipedes, Class Diplopoda, with two pairs of feet or legs per segment, release a noxious odor when feared. The related centipedes, Class Chilopoda, including the house centipede (Scutigera coleoptrata), with one pair of legs on each segment, give a painful bite when handled.
These organisms do not cause damage, but the millipede feeds on decaying matter, while the centipede feeds on insects and small invertebrates. Thus, aggressive control is not necessary, however, the pheromone Z-9-tricosene and good sanitation practices are highly effective.
