Flies

Domestic flies, often called "Filth Flies," are not only a nuisance by their presence, but are important from a human and animal health standpoint. House flies may spread diseases such as conjunctivitis, poliomyelitis, typhoid fever, tuberculosis, anthrax, leprosy, cholera, diarrhea and dysentery. They may serve as intermediate hosts for parasitic tapeworms on poultry or parasitic roundworms on horses. Certain larvae of blow flies, bottle flies, screwworm flies and flesh flies may feed on dead as well as living tissue of mammals, causing blood poisoning and even death, especially in sheep. Stable flies bite painfully, sucking blood from humans and animals. False stable flies do not bite, but spread certain diseases, whereas the little house fly hovers in mid air in the middle of rooms.

Gnats

Fungus gnats occasionally become a nuisance indoors when adults emerge in large numbers as mosquito-like insects from potted plants or flower boxes containing damp soil rich in humus. Adults are attracted to lights and are often first noticed at windows. Larvae or maggots, which feed in soil high in orangic matter, can injure the roots of bedding plants, African violets, carnations, cyclamens, geraniums, poinsettias and foliage plants. Plant symptoms may appear as sudden wilting, loss of vigor, poor growth, yellowing and foliage loss. Some are serious pests in mushroom houses. Fungus gnats inhabit fungi or dead plant materials and are harmless to humans and animals.

Grubs

The grubs that you see in the lawn are the larvae of Japanese beetles, June beetles, and chafers. These grubs are C-shaped, off-white in color with a dark head. They eat the roots of grass, causing irregularly shaped patches of wilted, dead or dying grass in April and May, and again in August to mid-October. With a serious infestation, the turf can be lifted up from the soil and rolled back like a carpet. If the damage to the grass is not too severe, the grass will recover with normal watering and fertilizing. Lawns that are heavily damaged by grubs will have a yellowish tinge and will feel spongy when walked on.

Hornets

Paper wasps and hornets may become a nuisance when nesting around homes and other structures where people live, work or play. Although considered beneficial to agriculture, (since northern or paper wasps feed abundantly on corn earworms, armyworms, tobacco hornworms, etc. and hornets on house flies, blow flies, harmful caterpillars, etc.), it is their painful stinging ability that causes alarm and fear. Nevertheless, unless the threat of stings and nest location present a hazard, it is often best to wait for Mother Nature to kill these annual colonies with freezing temperatures in late November and December. Stinging workers do not survive the winter, and the same nest usually is not reused the following year, except by the yellow and black dominulus paper wasp, on occasion.

Millipedes

Millipedes normally live outdoors but may become nuisance pests indoors by their presence. At certain times of the year (usually late summer and autumn) due to excessive rainfall or even drought, a few or hundreds or more leave the soil and crawl into houses, basements, first-floor rooms, up foundation walls, into living rooms, up side walls and drop from the ceilings. Some homeowners as early as late June have reported annoying populations accumulating in swimming pools. Fall migrations during rainy and cool weather may result as a natural urge to seek hibernation quarters. Heavy continuous rainfall in newly developed wooded areas with virgin soil (decaying organic matter habitats) are often troublesome sites. Millipedes do not bite humans nor damage structures, household possessions or foods. They can give off a disagreeable odor and if crushed, leave an unsightly mess.

Mites

Certain mites migrate from birds, rodents, food materials, vegetable matter and house dust, either attacking or annoying humans. Some mites can be detected with a hand lens, while others require microscopic examination of skin scraping or even dust from vacuum cleaner bags. Mite irritations can be confused with entomophobia (fear of insects) in certain people. Mite diagnosis is often difficult because specimens must be collected and identified by trained specialists before treatment can be made.

Mosquitoes

Mosquito are capable of transmitting serious, possibly even fatal diseases, such as mosquito-borne encephalitis and malaria to humans. Even in the absence of disease transmission, mosquito bites can result in allergic reactions producing significant discomfort and itching. In some cases excessive scratching can lead to bleeding, scabbing, and possibly even secondary infection. Children are very susceptible to this because they find it difficult to stop scratching. Frequently, they are outside playing and do not realize the extent of their exposure until it is too late.

Moths

Even though moths are much more common than butterflies, people always refer to butterflies when speaking about the lepidoptera. In fact almost 95 % of all the lepidoptera are moths. The subdivision is based on differences in lifestyle between butterflies and moths. The most obvious difference is that butterflies are active during the daytime and moths during the night-time.

Scorpions

Scorpions are venomous arthropods of the class Arachnida and are considered relatives of the spiders, mites, ticks and harvestmen. There are approximately 1,300 species of scorpions worldwide, characterized by an elongated body and a segmented tail that is tipped with a venomous stinger.

Silverfish

Silverfish and firebrats eat a wide variety of foods, including glue, wallpaper paste, bookbindings, paper, photographs, starch in clothing, cotton, linen, rayon fabrics, wheat flour, cereals, dried meats, leather and even dead insects. Silverfish often live in damp, cool places such as basements and laundry rooms. Sometimes, they are found in a bathtub, sink or washbasin, unable to climb out. Firebrats live in hot, humid places such as attics in summer and near furnaces, fireplaces and heat pipes in winter.
