Cockroaches are among the most common insects. They produce odorous secretions, and these secretions affect the flavor of foods. Disease-producing organisms, such as bacteria, have been found on cockroach bodies. Gastroenteritis is the principal disease transmitted by cockroaches. These include food poisoning, nausea, abdominal cramps, vomiting, diarrhea, dysentery, and other illnesses. Organisms causing these diseases are carried on the legs and bodies of cockroaches and are deposited on food and utensils as cockroaches forage. Cockroach excrement and cast skins also contain a number of allergens to which many people exhibit allergic responses, such as skin rashes, watery eyes, and sneezing. For some very allergic people, and particularly for those who also have a lung disease such as asthma, allergic attacks to cockroach allergens can be very serious and even life threatening.
A German Cockroach is the most common cockroach species in houses, apartments, restaurants, hotels, and other institutions. Adult females can produce from 4 to 8 egg capsules in their lifetime. Each capsule contains 30 to 48 eggs. It usually takes 20 to 30 days from the time of initial formation of the first egg capsule until it hatches.
The American Cockroach is the largest of the common species, growing 1-½ inches or more in length. Egg capsules are formed at the rate of 1 per week until from 15 to 90 capsules have been produced. Each capsule contains 14 to 16 eggs.
The Oriental Cockroach is referred to as the "water bug". Adults are very dark brown or nearly black and usually have a somewhat greasy sheen to their body. Females will produce an average of 8 capsules, each containing 16 eggs, which will hatch in about 60 days under room conditions. If water is available they can live for a month without food.
Ants are the most successful of insects. They may affect us adversely by stinging or biting; invading and contaminating food; nesting in lawns, golf courses, or within premises; stealing seeds from seed beds or feeding on germinating seeds; defoliating or gnawing into plants and plant products; fostering other injurious insects (e.g., aphids or scale insects on ornamental plants); gnawing holes in various types of fabrics; removing rubber insulation from telephone wires or other equipment; killing young poultry, birds, livestock, or game; simply annoying humans and animals with their presence; and possibly transmitting certain human diseases after crawling over sputum, feces, carrion, and so forth.
Honey Bees, Africanized Killer Bees, Wasps, Hornets, and Yellowjackets are all found in Nevada. Bees and wasps are frequently dangerous because of allergic response to their painful stings. Yellowjacket workers (Family Vespidae), are more apt to sting people during the latter part of their annual cycle, in August or September. In addition to causing intense pain, vespid wasp or social bee venoms contain proteinaceous materials that can cause severe allergic reactions in some individuals. Some people may even go into shock and die of suffocation as their lungs fill with fluid after being stung by a social bee or social wasp. Fortunately, the percentage of our population allergic to these venoms is quite low, probably less than 1 percent. Control of these hymenopterous pests may be warranted when they choose nesting locations too close for comfort. For example, under the front steps of a home, under eaves of a porch, in a school playground, or near the pole supporting a clothesline, etc…These circumstances create imminent hazard.
Africanized Honeybees and how they differ from other bees. First, they are more aggressive than other strains of honeybees, and gradually displace other strains. Second, colonies of Africanized bees are much more likely to change location, than the domesticated honeybees. Third, Africanized honeybees are much more aggressive in attacking animals, including humans, that disturb the colony. The defense zone of attack for their nests is up to 100 feet. When disturbed they will pursue anything that agitates the colony up to 4 football fields, 400 yards. If you try to escape by jumping in a pool they will wait until you come up for air. Finally, Africanized bees sometimes prefer nesting areas lower to the ground.
Ticks have four stages in their life cycle: egg, larva, nymph, and adult. Adult female hard ticks feed only once and lay one large batch of eggs, often containing as many as 10,000 or more eggs. Certain ticks carry organisms of such diseases as Rocky Mountain spotted fever, Lyme disease, typhus, rickettsial pox, relapsing fever, tularemia, Colorado tick fever, and Texas cattle fever. Another health threat posed by certain ticks attacking humans and other animals involves a poorly understood condition called tick paralysis. This occurs during the feeding process when the host is afflicted with a paralytic condition that develops gradually and may result in death.
Pillbugs and Sowbugs are crustaceans. Although they are related to shrimp and crayfish you probably won't find them on a menu, at least not in this country. However, you will find them under mulch or vegetable debris of all kinds beneath objects on damp ground. A heavy infestation indoors generally indicates that there is a large population immediately outside the building.
Crickets commonly invade the home. The house and field crickets are found in fields and near construction areas, especially in new developing areas. Crickets become displaced and may select your home as their next ideal nesting ground. They find harborage under rocks, air conditioning units, plumbing penetrations, garages, and near drip systems in desert landscaping common to the Las Vegas area. House crickets invade houses in great numbers. They are omnivorous, eating or drinking almost anything that is available. In households, they may chew on or damage silk, woolens, paper, fruits, and vegetables. Call Anderson Pest Control before your cricket problems reach infestations comparable to those found in the Bible.
Earwigs are insects that are readily recognized by the pinchers or forceplike appendages at the end of the abdomen. Some people refer to them as, "pincher-bugs." They are often transported great distances in potted plants, nursery stock, or other plant material. They sometimes build up to large numbers in warm weather and then may invade homes or other structures.
Scorpions are very common desert pests. In fact, in Las Vegas you probably built your home in or around a few scorpions. Most scorpions are active at night. During the day they hide under bark, boards, and rocks or in rubbish. In houses they are most often found in undisturbed areas, such as closets, seldom-used shoes, or folded clothing. See special services for our Black Light Night Inspection, and Anderson Pest Control will follow up with a management program tailored to your specific needs.
Spiders have a characteristic appearance easily recognized by most people. Remember that a spider made every cobweb; so if you think you are spider-free, check again. Under most conditions outdoors, spiders are considered beneficial because they feed on insects. However, they are undesirable to most homeowners when indoors, and the unsightly webbing spiders use to catch prey usually outweighs this beneficial behavior. For this reason Anderson Pest Control will remove all accessible exterior spider webs found around light fixtures, windows, doors, eaves, and more. Not only does this add to the cosmetic value of your home, it will also help reduce the number of spiders that invade your home.
The Black Widow is widely distributed over the warmer portions of the United States, so again Las Vegas is another target area for these poisonous spiders. Females are easily identified because of their globular, shiny black abdomen with two reddish or yellowish triangles on the underside. These triangles form an hourglass shape. Black widow spider venom contains toxins that are neurotoxic. The severity of a person's reaction to the bite depends on the area of the body where the bite occurs; the person's size and general sensitivity; the amount of venom injected; the depth of bite; the seasonal changes in venom potency; and the temperature. After a sharp pain, which usually disappears, convulsions and death may result. Please do not take any spider bite lightly, especially when a black widow is involved and consult your local physician. Antivenom specific for the black widow is readily available to most physicians.
The Brown Recluse Spider, Loxosceles reclusa Gertsch also inflicts a nasty bite. The initial bite is not intense, and is generally less troublesome than a bee sting. Within 8 to 12 hours the pain becomes quite intense, and over a short period of time a large ulcerous sore forms. This sore heals very slowly, difficult to treat even under the care of a doctor, and often leaves a large, ugly, and disfiguring scar. The brown recluse's body is yellow to dark brown and has a rather distinctive darker brown violin-shaped mark on the top of the cephalothorax. This spider has been widely reported in the western United States, and other venomous species of Loxosceles are distributed in the drier areas of the southwestern United States, including Southern Nevada.
Silverfish are flattened, long and slender, broad at the front and tapering gradually toward the rear. The antennae are long and slender. Three long, slender appendages are found at the rear of the body. All are wingless. They are found almost anywhere in the house. Silverfish can live for long periods without food. These insects are primarily a nuisance, but they do consume small amounts of human foods and contaminate it with their body scales and droppings. They can do considerable damage to some natural and synthetic fibers, books, and other paper products. They may also leave yellow stains, especially on linens.
Rodents have been responsible for, or implicated in, the spread of many diseases to people and domestic animals. Sanitation, effective drugs, and rodent and insect control programs have drastically reduced these threats. Unfortunately diseases are still spread by rodents. Some of these include the plague, murine typhus, rickettsial pox, salmonellosis, rat-bite fever, Weils disease, or leptospirosis, rabies, Lymphocytic choriomeningitis, trichinosis, typhoid, dysentery, and hantviruses to name a few.
The House Mouse originated in the grassy plains of central Asia. It was transported west on ships of early trade merchants and immigrants. It is capable of survival in almost any environment. With the exception of humans the mouse is the most numerous and widespread mammal on the earth. The house mouse is small, and slender. The ears are large, and the tail is semi-naked and as long as the head and body together. The fur is usually dark gray on the back and light gray on the belly. A female will typically produce about eight litters in her lifetime. There are typically 4-7 pups per litter. If conditions are good, she is capable of giving birth to a litter every 24 to 28 days. Young mice are sexually mature within 5 to 8 weeks. Do the math and the numbers are quite staggering.
European settlers and trading ships introduced the Norway Rat into the United States about 1775. It is the most widely distributed rat species in the United States, and is found in your city, perhaps in your neighborhood, may be in your own backyard. It has a stocky body, weighing between 12 and 16 ounces. The body fur is coarse and ranges from reddish to grayish brown with buff white underparts. The nose is blunt, and the ears are small, close set, and do not reach the eyes when pulled down. The tail is shorter as compared to that of the roof rat's tail. The average female rat has 4 to 7 litters per year and may successfully wean twenty or more pups annually.
The Roof Rat arrived in the Americas around 1607, aboard ship with the colonists at Jamestown. They are smaller and sleeker in appearance than the Norway rat. The color of the fur is usually grayish black. The tail is long and reaches the snout when pulled over the body. Reproductive potential is similar to the Norway rat although less prolific, producing only 4-8 pups per litter. Around in buildings, it is common to find Norway rats inhabiting the ground and lower portions of the building, while roof rats establish themselves in either the exterior vegetation or the upper stories, attics, and soffits of the building.
City Pigeons or "flying rats," as many disgruntled Las Vegans describe them are here to stay. Friend or Foe? Pigeons can be nuisances, transmit diseases, contaminate our food, and deface our structures and many other items of importance in urban environments. They spread diseases like, histoplasmosis, ornithosis, salmonellosis, TGE, hog cholera, cryptococcosis, encephalitis, Newcastle disease, aspergillosis, toxoplasmosis, pseudotuberculosis, avian tuberculosis, and coccidiosis, not to mention seven or eight ectoparasites they may carry. They deposit their manure indiscriminately on sidewalks, people, buildings, park benches, statues, and cars. This can permanently stain and cause premature rusting and corrosion of structures, statues, planes, boats, and cars. Large amounts of droppings can severely damage or kill valuable trees and other vegetation. The Federal Food, Drug, and Cosmetic Act prohibits any conditions in which a food might become contaminated. Birds cannot be permitted to exist within or even on the exterior of a food facility. Please consider the risks and call Anderson Pest Control.
