Name: American cockroaches

American cockroach (Blattaria: Blattidae, Periplaneta americana) adults are 1 and 1/2 inches long and are reddish brown and have a yellowish margin on the body region behind the head. When disturbed, may run rapidly and adults may fly. Immature cockroaches resemble adults except that they are wingless.

American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures around 84 degrees Fahrenheit and do not tolerate cold temperatures. In residential areas, these cockroaches live in basements and sewers, and may move outdoors into yards during warm weather. They feed on a wide variety of plant and animal material.

Females produce egg cases and carry them protruding from the tip of the abdomen for about two days. Egg cases are then generally placed on a surface in a hidden location. Egg cases are 3/8 inch long, brown, and purse shaped. Immature cockroaches emerge from egg cases in 6 to 8 weeks and require 6 to 12 months to mature. Adult cockroaches can live up to one year.

This light to dark brown ant, about one-tenth inch long; antenna has 12 segments. The Argentine ant is readily adaptable and can nest in a great variety of situations. Colonies are massive, and may contain hundreds of queens, nests are usually located in moist soil, next to or under buildings, along sidewalks, or beneath boards.They travel in trails, forage day and night. This ant can eat almost anything but prefers sweets.It has no important natural enemy in the United States.

Asian lady beetle, Harmonia axyridis
The Asian lady beetle is a common and widespread wintertime household pest across most of the United States. Large numbers of these insects invade homes during the fall and remain active over the winter, especially in late winter when temperatures warm and days get longer. Ladybugs do not feed and cannot reproduce indoors; they have not multiplied indoors although it must seem that way to homeowners who have been inundated with them.

When lady beetles stranded indoors for the winter are emerging from inside house walls, there is no control option more practical or effective than repeated vacuuming. Spraying insecticides has little or no effect. However, one alternative for homeowners unable/unwilling to pursue wintertime ladybug control via vacuuming is the use of lady beetle traps as indoor collecting devices.

Australian cockroach (Periplaneta australasiea (fabricius)
The Australian cockroach closely resembles the American cockroach , but can be separated from it by its slightly smaller size , about 1 1/4 to 1 3/8 inches long and the wings of both sexes cover the abdomen. The Australian cockroach life cycle requires about one year from egg to adult. This world-wide species has become established in the southern U.S. and in many greenhouses. In the United States, it is most abundant in Florida and the coastal southern states, and in California it ranges as far north as San Francisco. It lives outdoors around the perimeter of houses and is the most prevalent cockroach outdoors in south Florida. Australian cockroaches are prevalent in leaf litter, in and around shrubs, flowers and trees, tree holes, wood piles, garages, crawl spaces, attics, and greenhouses. It is a pest when it enters homes where it may eat holes in clothing and feed upon book covers. It is apparently more vegetarian than the other cockroaches.
Name: Baldfaced Hornets

The Bald faced hornet (Dolichovespula maculata) are black and white, 5/8 to 3/4 of an inch long and are actually a yellowjacket.

Its nest is a gray “paper” envelope with several layers of combs inside. A mature nest is bigger than a basketball, but pear-shaped, with the larger end at the top and an entrance hole near the bottom.
A single, over-wintering queen begins building the nest in the spring. She lays eggs and tends the first batch of larvae that develop into workers. These workers tend new larvae and expand the nest throughout the summer. A mature colony can have several hundred workers by the end of the summer. In fall, workers die and next year’s queens find over-wintering sites.
Baldfaced hornets are beneficial, capturing insects (often including other yellowjackets) to feed to their larvae. Though larger than other yellowjackets, Baldfaced hornets are generally more docile. But they can become aggressive and will sting when their nest is disturbed or threatened.
A Baldfaced nest is usually constructed high in a tree. In these cases the nest is best left alone. In fact, Baldfaced hornet nests are often first noticed in fall when leaves drop, exposing the nest. By this time the hornets are dead or dying, and the nest will not be reused.
Occasionally you will find a Baldfaced nest built on the side of a building, in low shrubbery, or even in an attic or shed. Nests in these sites will probably need to be eliminated.
Stinging/Biting Pest
Name: Bed Bugs

The common bed bug (Cimex lectularius Linnaeus) probably received its name from its close association with human bedding. Bed bugs often seek refuge in bedding during the day and feed on the bed’s occupants at night. These insects are known by several names: wall louse, house bug, mahogany flat, red coat, and crimson ramblers, to name a few.

While bed bugs feed primarily on humans, they also feed on other mammals, poultry, and other birds. Their host range is confused by the fact that the insect family Cimicidae, of which the common bed bug is a member, has several closely related species with similar habits and appearance. Among those reported in New Mexico are the western bat bug (Cimex pilosellus Horvath) and the swallow bug (Oeciacus vicarius Horvath). While these insects prefer other hosts, they can, when stressed, feed on humans.

It has never been proven that bed bugs are disease carriers in the United States. They are spread mainly by clothing and baggage of travelers and visitors, secondhand beds, bedding materials, furniture, and laundry.

The mature bed bug is a brown- to mahogany-colored, wingless insect. Its size depends on how recently it has eaten a blood meal. An unfed bed bug is between 1/4 and 3/8 inches long. The upper surface of its body has a papery, crinkly, flimsy appearance. When engorged with blood, its body becomes elongated and swollen, and its color changes from brown to dull red. The color, size, and shape change from an unfed to a full bug is remarkable.

Bed bug eggs are white and about 1/3-inch long. Under favorable conditions the female bed bug lays about 200 eggs at the rate of 3 or 4 per day. Eggs have a sticky coating and stick to objects where they are laid. It usually takes the eggs 6 to 17 days to hatch, and the newly emerged nymphs will feed immediately. A bed bug goes through five molts (shedding of its skin) before it reaches maturity. Depending on environmental factors and the availability of food, there can be considerable variation in developmental rate. Bed bugs may live for several weeks to several months without feeding, depending on temperature.

A bed bug generally feeds at night, but if it is hungry and the area has a dim light, it may feed during the day. A bed bug generally pierces the skin of humans as they sleep. It injects a fluid into the human skin to aid in obtaining blood. Often this fluid causes a welt on the skin that becomes irritated, inflamed, and itchy. If left undisturbed, a full-grown bed bug becomes engorged with blood in 3 to 5 minutes. It then crawls into hiding, remaining there for several days to digest its meal. When hunger returns, the bug emerges from hiding and seeks another blood meal.

Heavily used hiding places are evident by black or brown spots of dried blood excrement on the surfaces where the bugs rest. Eggs, egg shells, and cast skins may be found near these places. Usually there is an offensive odor where bed bugs are numerous. In early infestations the bed bugs are found only about the tufts, seams, and folds of mattresses and daybed covers; later they spread to cracks and crevices in the bedsteads. If allowed to multiply, they establish themselves behind baseboards, window and door casings, pictures, and moldings, and in furniture, loosened wallpaper, and cracks in plaster and partitions.
