Scorpions
Scorpions are usually brown in color and range from about 2.5cm to 20cm (about 1 to 8 in) in length. The scorpion is nocturnal and feeds mainly on spiders and insects. The young are born live and remain with the mother for a short period. When capturing a victim with its claws, the scorpion inflicts a disabling sting with its tail. In most species, the string is painful, but not fatal to humans, although the string of one species found in the United States has proved fatal to young children and is potentially fatal to adults. Other areas of the world have more dangerous scorpion species; the poison involved is a neurotoxin, attacking the nervous system. Theoretically, a single female could account for up to 91,000 offspring within a three month period. Eliminating food sources and baiting near problem areas are the best solution.
Earwigs
Despite a European superstition that believed the earwigs could burrow into the brain through one's ear, they are harmless to humans. They will feed on leftovers, especially greasy foods, and will chew small irregular holes in house plants. They are found in and around homes because they are attracted to the moisture and decaying organic matter. Controlling moisture levels around the foundation and exposed faucets is essential for extended prevention.
Silverfish
These pests often are found by homeowners in sinks or tubs when they are unable to climb out. Growing to a length of 1/2" to 3/4" long, they are fragile insects with two long antennae, almost as long as their bodies and the distinctive three appendages (that look like antennae) at the rear. They are typically a pearly-grey to light charcoal color (hence their name) and occasionally referred to as 'bristletails'. Cleanliness is not really a factor in silverfish infestation because they can live in insulation, books, between walls, old paper products, and some fabrics. After controlling problem infestations, reducing damp areas within the home will help prevent their return.
Sow Bugs
Sow bugs are land crustaceans which look very similar to pill bugs, at least at first glance. Sow bugs are small crustaceans with oval bodies when viewed from above. Their back consists of a number of overlapping, articulating plates. They have 7 pairs of legs and antennae which reach about half their body length. Most are slate gray in color and may reach about 15mm long and 8mm wide.
Pill Bugs
Unlike the sow bug, the pill bug has a rounder back, from side to side, and a deeper body, from back to legs. When disturbed, it frequently rolls into a tight ball with its legs tucked inside, much like its larger but dissimilar counterpart, the armadillo.
The presence of sow bugs or pill bugs in the living quarters of a home is an indication of high moisture conditions. This condition will also contribute to a number of other problems including mildew, wood rot, and a good breeding environment for other insects.
