AMERICAN ROACH
It occurs throughout the United States as a common indoor and outdoor cockroach. This species is common outdoors in landscape plantings, in sewers or storm drain systems, and in lower areas of buildings where moisture may be greater. It may inhabit storm drains in huge numbers, emerging though man-hole covers at night to invade buildings. I have even seen them come up through house drains. They will feed on most carbohydrate or protein based materials, including human hair or finger and toenails. Each female produces around 10 egg capsules, carrying the capsule for a day or two and then carefully placing it in a protected location. Each egg capsule has an average of 15 eggs in it and hatch in about 45 days.

CENTIPEDE
The most common centipedes found around structures are fast-running predators of other arthropods, such as insects, as well as earthworms and snails. They generally are nocturnal, hiding under boards, rocks, or vegetation on the soil during the daytime, and seen only when they are disturbed and uncovered. Centipedes do have the ability to inject venom through the pair of appendages directly behind the head, called maxillipeds. The North American species are relatively harmless to humans, while species in tropical Latin America may cause a serious reaction. At least one large western species also can cause severe pain with its bite. Some species may live up to 6 years. Females lay their eggs one at a time, usually burying it under a shallow layer of soil to protect it from being eaten, possibly even by the males.

Identification: Centipedes are very long and narrow, and flattened from top to bottom. There may be a great many pairs of legs, but they will have a single pair on each segment of the body, separating them from the millipedes. Color is usually dark reddish brown, although some kinds have a bluish-green tint on a tan background. They have a pair of very long antennae and the last pair of legs is often much longer than the ones before it and they project backward.

BLACK WIDOW
The black widow spiders are the most dangerous spiders with respect to human health in the U.S. They are one of the few spiders capable of biting humans that inject a neurotoxin, and the effect of the bite can be serious and potentially fatal. Only females bite humans, but both males and females construct webs to capture other prey, primarily flying insects. Males also enter a female’s web for mating, and if the female is not receptive the male may be eaten. The life span of black widow females averages around 180 days as an adult, taking about 3 months to reach maturity. Males mature in about 70 days and live only about 30 days after that. The female may produce up to 9 egg sacs with about 350 eggs per sac on average. She will be most aggressive and defensive of her webbing while she is guarding these eggs, as well as being more hungry following egg production. The new spiderlings emerge from the sac and remain near it for a day or two, but then they undergo “ballooning” to disperse, creating long silk strands that are carried away by the wind. Black widows are generally reclusive spiders that create their webs in areas of inactivity. The web is made of extremely strong silk that is very sticky, and it has a very haphazard appearance without the symmetry of some other spiders.

PAVEMENT ANTS
The common name of these ants is derived from their habit of creating nests under asphalt or concrete slabs, pushing small mounds of soil out through cracks and expansion joints. The nests are usually very shallow, and may also be found under debris or objects on the ground, as well as within structures near heat sources in the winter. Activity is generally begun at dusk or later, and the workers forage commonly within structures, where they may feed on greases, pet foods, or sweet materials. Outdoors they feed on honeydew, fruits, or other materials. Swarming is most common in the spring, with large numbers emerging from numerous colonies over a period of several days. They are attracted to lights and may find their way indoors at night.

SCORPIONS
True scorpions are characterized by the presence of an elongated “tail-like” appendage off the abdomen, tipped by a sharp stinger. They are arachnids, and have four pairs of legs, a pair of enlarged palps that are modified as claws, and the head and abdomen are combined as a cephalothorax. All true scorpions are predators that feed on other animals, using their stinger to subdue the prey or as a defensive weapon. The venom of most species is considered of little health consequence to humans. Scorpions may live up to 5 years or longer as adults, and the nymph stages usually complete in about one year. After mating the male scorpion may find itself being eaten by the female. Females do not lay eggs, but instead give birth to living young which climb onto her body and remain there until after their first molt, around one or two weeks later. Up to 100 young are possible from a single female.

GERMAN ROACH
The German roach is a nocturnal animal, strongly avoids light, cannot fly, and in almost all situations will be found indoors. Infestations normally begin by the introduction of roaches in packages. The biological potential of this species is enormous, with females producing an average of 5 egg capsules in their lifetime, each with an average of 30 eggs in it. The time from egg to mature adult averages about 3 months, allowing 4 generations of the insects each year. Female adult roaches live for about 200 days. Females carry the egg capsule until one day before the eggs are to hatch, providing necessary moisture into the eggs. Her activity level is low while she is in this “gravid” stage. This species has a higher moisture requirement than many other species, and is most likely to be living near moisture sources and in humid areas. First instar nymphs often remain in hiding, feeding on the f***l material of other roaches. Older roaches are extremely variable in their diets, feeding on virtually any materials in a food environment. They may also nibble on human hair or finger and toenails.

SUBTERRANEAN TERMITES
With very rare exception colonies are located in the ground, with foraging done from these colonies into structures or other wood sources. There is a true worker caste, with adult workers, soldiers, and alates in the colony. It is possible that a colony can have up to two hundred thousand workers or more, and several separate colonies may exist near and be foraging in a single structure. Swarming by the alates may consist of many hundreds of alates from the colony, and many colonies in an area releasing swarmers simultaneously. This usually occurs in late morning to mid-day on a sunny day following a rainfall. Most swarming is in the spring, but fall swarms are also common, and a colony will be at least 3 years old before it produces swarmers. The wings are shed shortly after the flight takes place.

WHIP SCORPION, VINEGARROON, VINEGARONE
Whiptail scorpions are so named due to the long, thin tail that extends from the tip of the abdomen. Their alternate name of vinegarroon or vinegarone comes from the ability of this animal to defend itself with an accurate spray of acetic acid, or vinegar, from the tail end. Other than this they are considered harmless and beneficial, having no venom and no ability.

WIND SCORPION, SUN SPIDER, SUN SCORPION
While the solpugids have an impressive array of jaws that they use to rip apart their prey, they are considered to be harmless to humans and are incapable of biting. They have no venom and no stinger. Their palps are modified as long, tubular arms that they use to capture their prey with, guiding it to their jaws where it is then crushed and eaten, generally in liquid form. They are beneficial predators that are extremely fast and aggressive, moving about at night and hiding in daylight hours. It is not uncommon for them to enter structures.
Identification:
Solpugids can be as long as 2 inches in body length, with colors ranging from yellowish to grayish brown. The abdomen is very large, tear-drop shaped, and with a wide, rounded posterior end. There is a sparse covering of hairs over their entire body. The jaws appear as 4 long, separated mandibles, a pair on either side, with curved tips and several teeth along their length.

HARVESTER ANTS
Harvester ants gather seeds and vegetation for their food, and are very unlikely to enter structures. However, they may be common in urban areas, and with their ability to sting and their large size they may become a problem. In addition, their activities can have a serious effect on agricultural crops or ornamental plantings. Nest openings are identified by the large, circular, flat area around them, created by the workers as they clear debris and soil from the underground chambers. This area averages 12 feet in diameter, and distinct paths lead from it to over 200 feet away for foraging. Nests may go as deep as 15 feet, with numerous chambers, and the population of workers may exceed 12,000. Swarming by reproductives occurs throughout the summer months.
