BLACK WIDOW

Female black widows often exhibit various red markings on the dorsal or top side of the abdomen, commonly two red spots. However, black widow young are believed to have at least some sort of marking on their abdomens. Adult male black widows are half the size of the females, and are usually gray or brown rather than black and red; while they may sometimes have an hourglass marking on their ventral abdomen, it is usually yellow or white, not red.

Many injuries to humans are due to defensive bites delivered when a spider gets unintentionally squeezed or pinched. Some bites are thought to result from a spider mistaking a finger thrust into its web for its normal prey, or in cases where a female is protecting an egg sac.

SUN SPIDER

Most species of Solifugae live in deserts and feed opportunistically on ground-dwelling arthropods and other small animals. Some species grow to a length of 300 mm (12 in) including legs.

Although they do not normally attack humans, their powerful jaw can penetrate human skin, and painful bites have been reported.

GERMAN COCKROACH

The species of cockroach found here in Yuma is the German Cockroach.  This cockroach can be seen in the day occasionally, especially if the population is large or they have been disturbed. However, sightings are most commonly reported in the evening hours, as they are most active at night.This type of cockroach can emit an unpleasant odor when excited or frightened.

AMERICAN  COCKROACH

American cockroach adults grow to an average length of around 4 cm (1.6 in) and about 7 mm (0.28 in) tall. They are reddish brown and have a yellowish margin on the body region behind the head. Immature cockroaches resemble adults except they are wingless.

The odorous secretions produced by American cockroaches can alter the flavor of food. Also, if populations of cockroaches are high, there will be a strong concentration of this odorous secretion. Cockroaches can pick up disease-causing bacteria. such as Salmonella, on their legs and later deposit them on foods and cause food infections or poisoning. House dust containing cockroach feces and body parts can trigger allergic reactions and asthma in certain individuals.

ORIENTAL  COCKROACH

The oriental cockroach tends to travel somewhat more slowly than other species. They are often called “waterbugs” since they prefer dark, moist places. They can often be found around decaying organic matter, and in sewers, drains, damp basements, porches, and other damp locations. They can be found outside in bushes, under leaf groundcover, under mulch, and around other damp places outdoors. They are major household pests in parts of the northwest, mid-west, and southern United States.

SCORPION

The Arizona bark scorpion is particularly well adapted to the desert: layers of fat on its exoskeleton make it resistant to water loss. Nevertheless, bark scorpions hide during the heat of the day, typically under rocks, wood piles, or tree bark. Bark scorpions do not burrow, and are commonly found in homes, requiring only 1/16 of an inch for entry.

Arizona bark scorpions prefer that have sufficient moisture and humidity to support insects and other prey species. The popularity of irrigated lawns, and other systems which increase environmental humidity in residential areas, has led to a massive increase in the number of these animals in some areas.

These scorpions can climb walls, trees, and other objects with a sufficiently rough surface. Bark scorpions prefer an upside down orientation, which often results in people being stung due to the scorpion being on the underside of an object.

The bark scorpion is the most venomous scorpion in North America, and its venom can cause severe pain (coupled with numbness and tingling) in adult humans, typically lasting between 24 to 72 hours. Temporary dysfunction in the area stung is common.  It also may cause the loss of breath for a short period of time. Due to the extreme pain induced, many victims describe sensations of electrical jolts after envenomation.

INDIAN HOUSE CRICKET

Light yellowish-brown or tan in color with darker bands and spots, about 3/4-inch long when mature; these are the most common and troublesome crickets. They often gather around foundations and doors outside and readily come inside through cracks or openings. They are the only type of cricket that may live and produce young indoors. They typically hide during the day and come out at night to feed on crumbs, pet food, and plant debris.

Indian House Crickets are primarily nuisance pests. The males attract females by “chirping” at night, which can be extremely annoying for homeowners. The “chirping” sound is produced by the males rubbing their wings together. These crickets also may produce piles of unsightly droppings. When there are extremely high numbers of Indian house crickets they may feed on fabrics and drywall. Outdoors, they may damage young garden plants and annual flowers.

FIELD CRICKET

Larger than Indian house crickets (slightly more than 1 inch when mature) and usually dark brown to shiny black in color, field crickets also enter houses and buildings. These crickets prefer toJerusalem Cricket The song of the field cricket is temperature dependent. The tone and tempo drop with a drop in temperature. Count the chirps in 13 seconds, add 40, and you will have the approximate temperature in degrees Fahrenheit. live and breed outdoors where they feed on several kinds of plants. Occasionally they invade homes in search of hiding places but do not produce young indoors.

Field crickets are known to chew on and damage woolens, cottons, silks, synthetic fabrics, furs and carpeting. Clothes with perspiration stains or food spills are particularly attractive. Outdoors, they may damage young garden plants and annual flowers.

DESERT IRONCLAD

The exoskeleton of these beetles is indeed extreemly tough. Hikers often find the ancient, empty shells of these beetles many years after the insect has died. Hobbiests have reported keeping these insects alive in captivitiy for 10 years. They find on a wide range of materials such as fruit, dead leaves and dead insects. The immature stage is a grub that lives in the soil presumably feeding upon decayed plant material.

BEDBUGS

Bed bugs are parasitic insects that feed exclusively on blood. The name of the “bed bug” is derived from the preferred habitat of Cimex lectularius: warm houses and especially nearby or inside of beds and bedding or other sleep areas. Bed bugs are mainly active at night, but are not exclusively nocturnal. They usually feed on their hosts without being noticed.

A number of adverse health effects may result from bed bug bites, including skin rashes, psychological effects, and allergic symptoms.

FIRE ANTS

In the US the FDA estimates that more than US$5 billion is spent annually on medical treatment, damage, and control in fire ants-infested areas. Furthermore, the ants cause approximately $750 million in damage annually to agricultural assets, including veterinarian bills and livestock loss, as well as crop loss.Between 30 and 60% of people living in fire ant-infested areas are stung each year.

ARGENTINE ANTS

Argentine ants are a common household pest, often entering structures in search of food or water (particularly during dry or hot weather), or to escape flooded nests during periods of heavy rainfall. Argentine ant colonies almost invariably have many reproductive queens, as many as eight for every 1,000 workers, so eliminating a single queen does not stop the colony’s ability to breed. When they invade a kitchen, it is not uncommon to see two or three queens foraging along with the workers.

Due to their nesting behavior and presence of numerous queens in each colony, it is generally impractical to spray Argentine ants with pesticides or to use boiling water as with mound building ants. Spraying with pesticides has occasionally stimulated increased egg-laying by the queens, compounding the problem.

HARVESTER ANTS

The Maricopa harvester antPogonomyrmex maricopa, is one of the most common species of harvester ant species found in Arizona, USA. Its venom is believed to be the most toxic insect venom in the world.

SILVERFISH

Silverfish consume matter that contains polysaccharides, such as starches and dextrin in adhesives. These include glue, book bindings, plaster, paints, paper, photos, sugar, coffee,  hair, carpet, clothing and dandruff. Silverfish can also cause damage to tapestries. Other substances that may be eaten include cotton, linen, silk, synthetic fibres and dead insects or even its own exuvia (moulted exoskeleton). During famine, a silverfish may even attack leatherware and synthetic fabrics. Silverfish can live for a year or more without eating.

Silverfish are considered a household pest, due to their consumption and destruction of property. Although they are responsible for the contamination of food and other types of damage, they do not transmit disease.

PINACATE BEETLE

The pinacate beetle, also known as the stink beetle, is noted for its defensive tactic of standing on its head and squirting a noxious spray. This has earned it the additional names of clown bug and stink bug, names also applied to other unrelated insects.
