ANTS

Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organized colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist mostly of sterile, wingless females forming castes of "workers", "soldiers", or other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens". The colonies are described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony.

BED BUGS

Bed bugs can cause many health effects, including skin rashes, psychological effects, and allergic symptoms. They can be infected by at least 28 human pathogens, but no study has clearly found that the insect can transmit the pathogen to a human being. Bed bug bites or cimicosis may lead to a range of skin manifestations from no visible effects to prominent blisters.

Carpet Beetle

Carpet beetles come in two basic types: black and varied. Black adults are 3 to 5 mm long and have dark brown or black bodies; varied adults are 2 to 3 mm long and have black bodies with irregular white, brown, orange or yellow scales. Carpet beetles are destructive during their larval stage, feeding on a wide variety of items including carpet, felt, wool, skins, furs, stuffed animals, leather, feathers, hair, dander and insect meal. They are most active in dark and undisturbed areas. Due to their food selection, regular vacuuming is one of the best ways to keep them from infesting your home.

• Colour: Gray or blackish body, wings usually lacking dark areas but some species with entirely dark wings; eyes often large and green or purple with horizontal stripes
• Legs: 6
• Shape: Stout-bodied and without bristles
• Size: About 3/8 - 1 and 1/8” (10-30 mm) long
• Antennae: Yes
• Region: Found throughout North America

Carpet Beetle

Centipedes have a rounded or flattened head, bearing a pair of antennae at the forward margin. They have a pair of elongated mandibles, and two pairs of maxillae. The first pair of maxillae form the lower lip, and bear short palps. The first pair of limbs stretch forward from the body to cover the remainder of the mouth. These limbs, or maxillipeds, end in sharp claws and include venom glands that help the animal to kill or paralyze its prey.

Cockroaches

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.

• Colour: Brown, with pronounced banding across wings
• Legs: 6
• Shape: Oval
• Size:1/2" long
• Antennae: Yes

Fleas

Fleas are small flightless insects that form the order Siphonaptera. As external parasites of mammals and birds, they live by consuming the blood of their hosts. Adults are up to about 3 mm (0.12 in) long and usually brown. Bodies flattened sideways enable them to move through their host's fur or feathers; strong claws prevent them from being dislodged. They lack wings, and have mouthparts adapted for piercing skin and sucking blood and hind legs adapted for jumping. The latter enable them to leap a distance of some 50 times their body length, a feat second only to jumps made by froghoppers. Larvae are worm-like with no limbs; they have chewing mouthparts and feed on organic debris.

Flies

Flies are insects of the order Diptera (from the Greek di = two, and ptera = wings). they are commonly found in both suburban and rural areas near bodies water, adults flies are capable of flying for more than 30 miles they most often attack moving and dark objects. flies often rest on path and roads, especially in wood areas, where they wait for potential host.flies are attracted to light and will sometimes congregate at windows.

• Colour: Abdomen usually black and yellow pattered similar to bands.
• Legs: 6
• Shape: Wasp-like
• Size: Workers 3/8 to 5/8 of an inch long
• Antennae: Yes

Hornets

Hornets (insects in the genera Vespa and Provespa) are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets. Some species can reach up to 5.5 cm (2.2 in) in length. They are distinguished from other vespine wasps by the relatively large top margin of the head and by the rounded segment of the abdomen just behind the waist. Worldwide, there are 22 recognized species of Vespa, and three species of Provespa, which are unique amongst hornets in being nocturnal. Wasps native to North America in the genus Dolichovespula are commonly referred to as hornets, but are actually yellowjackets.

Maplebug

The boxelder bug or Maple bug (Boisea trivittata) is a North American species of true bug. It is found primarily on boxelder trees, as well as maple and ash trees. The adults are about 12.5 millimetres (0.49 in) long with a dark brown or black colouration, relieved by red wing veins and markings on the abdomen; nymphs are bright red.

Moths

Several moths in the family Tineidae are commonly regarded as pests because their larvae eat fabric such as clothes and blankets made from natural proteinaceous fibers such as wool or silk. They are less likely to eat mixed materials containing some artificial fibers. There are some reports that they may be repelled by the scent of wood from juniper and cedar, by lavender, or by other natural oils; however, many consider this unlikely to prevent infestation. Naphthalene (the chemical used in mothballs) is considered more effective, but there are concerns over its effects on human health.

Silverfish

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. They will damage wallpaper in order to consume the paste. Silverfish can also cause damage to tapestries. Other substances they may eat include cotton, dead insects, linen, silk, or even their 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 if water is available. Silverfish are considered household pests, due to their consumption and destruction of property.

Sow Bugs

Sowbugs are land crustaceans which look very similar to pillbugs, at least at first glance. Sowbugs are small crustaceans with oval bodies when viewed from above. Their back consists of a number of overlapping, articulating plates. They have 7 pairs of legs, and antennae which reach about half the body length. Most are slate gray in color, and may reach about 15 mm long and 8 mm wide.
Common names for woodlice vary throughout the English-speaking world. A number of common names make reference to the fact that some species of woodlice can roll up into a ball. Other names compare the woodlouse to a pig.

Spider

The House Spider are urban pests named after the comb-like row of bristles located on the tarsi of their fourth pair of legs. House spiders are common throughout the world, and their webs are most often found in corners, basements, crawlspaces, under furniture and around windows. The venom is necrotic, causing open, localized wounds that may be slow to heal.

Tent Caterpillars

Tent caterpillars are moderately sized caterpillars, or moth larvae, belonging to the genus Malacosoma in the family Lasiocampidae. Twenty-six species have been described, six of which occur in North America and the rest in Eurasia. Some species are considered to have subspecies as well. They are often considered pests due to their habit of defoliating trees. They are among the most social of all caterpillars and exhibit many noteworthy behaviors.
Tent caterpillars are readily recognized because they are social, colorful, diurnal and build conspicuous silk tents in the branches of host trees. Some species, such as the eastern tent caterpillar, Malacosoma americanum, build a single large tent which is typically occupied through the whole of the larval stage, while others build a series of small tents that are sequentially abandoned. Whereas tent caterpillars make their tents in the nodes and branches of a tree's limbs, webworms enclose leaves and small branches at the ends of the limbs.

Wasps

The most commonly known wasps such as yellow jackets and hornets are in the Vespidae family and are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently. Many of the solitary wasps are parasitoidal, meaning that they raise their young by laying eggs on or in the larvae of other insects. The wasp larvae eat the host larvae, eventually killing them. Solitary wasps parasitize almost every pest insect, making wasps valuable in horticulture for biological pest control of species such as whitefly in tomatoes and other crops
