常見害蟲種類 Pest Type
The name "bed bug" derives 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.They are not known to transmit any pathogens as disease vectors. Certain signs and symptoms suggest the presence of bed bugs; finding the insects confirms the diagnosis.
Bed bugs have been known as human parasites for thousands of years. At a point in the early 1940s, they were mostly eradicated in the developed world, but have increased in prevalence since 1995, likely due to pesticide resistance. Because infestation of human habitats has been on the increase, bed bug bites and related conditions have been on the rise as well.
白 蟻 的 威 力
Owing to their wood-eating habits, many termite species can do great damage to unprotected buildings and other wooden structures. Their habit of remaining concealed often results in their presence being undetected until the timbers are severely damaged and exhibit surface changes. Once termites have entered a building, they do not limit themselves to wood; they also damage paper, cloth, carpets, and other cellulosic materials. Particles taken from soft plastics, plaster, rubber, and sealants such as silicone rubber and acrylics are often employed in gallery construction. Humans have moved many wood-eating species between continents, but have also caused drastic population decline in others through habitat loss and pesticide application.
Termites are commonly viewed as pests in many countries, because of the damage they can cause to structures and similar nuisances. In April 2011, wood-eating termites were blamed for reportedly consuming more than $220,000 worth of Indian rupee notes.
Cockroaches are one of the most commonly noted household pest insects. They feed on human and pet food and can leave an offensive odor. They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans, particularly in
environments such as hospitals. Cockroaches are linked with allergic reactions in humans.One of the proteins that triggers allergic reactions is tropomyosin.These allergens are also linked with asthma.
General preventive measures against household pests include keeping all water and food stored away in sealed containers, using garbage cans with tight lids, frequent cleaning in the kitchen, and regular vacuuming. Any water leaks, such as dripping taps, should also be repaired. It is also helpful to seal off any entry points, such as holes around baseboards, between kitchen cabinets, pipes, doors, and windows with some steel wool or copper mesh and some cement, putty or silicone caulk.
木蟲成蟲身長約1/32 至1/4寸，身體呈長而平，通常是呈啡色及黑色。 蛀木蟲的成蟲多在木材的粗糙面的管孔或裂縫中產卵，孵化的幼蟲，開始蛀食木材內部，將木材蛀食成曲折孔道，表面留有蟲孔，並從圓孔中掉落粉未狀的排泄物。
麈蟎House Dust Mite
The house dust mite (HDM) is a cosmopolitan pyroglyphid that lives in human habitation. Dust mites feed on organic detritus, such as flakes of shed human skin, and flourish in the stable environment of dwellings. House dust mites are a common cause of asthma and allergic symptoms worldwide. The mite's gut contains potent digestive enzymes (notably proteases) that persist in their feces and are major inducers of allergic reactions such as wheezing. The mite's exoskeleton can also contribute to allergic reactions. The European house dust mite (Dermatophagoides pteronyssinus) and the American house dust mite (Dermatophagoides farinae) are two different species, but are not necessarily confined to Europe or North America; a third species Euroglyphus maynei also occurs widely. Unlike scabies mites or skin follicle mites, house dust mites do not burrow under the skin and are not parasitic.
Silverfish consume matter that contains polysaccharides, such as starches and dextrin in adhesives. These include book bindings, carpet, clothing, coffee, dandruff, glue, hair, some paints, paper, photos, plaster, and sugar. Silverfish can also cause damage to tapestries. Other substances they may eat include cotton, dead insects, linen, silk, or even its own exuvia (moulted exoskeleton). During famine, a silverfish may even attack leatherware and synthetic fabrics. Silverfis⋯⋯h can live for a year or more without eating.
Silverfish are considered household pests, due to their consumption and destruction of property.However, although they are responsible for the contamination of food and other types of damage, they do not transmit disease.
Earwigs, house centipedes, and spiders are known to be predators of silverfish.
Silverfish are not harmful to humans and their bite is not strong enough to penetrate human skin. In fact, many of the bites attributed to a silverfish are those made by the house centipede, which is commonly found within the same habitat and looks somewhat similar
