Bats, while some species can be larger, bats are usually not much bigger than a house mouse. The wingspan of the two most common Canadian species, the little brown bat and the big brown bat, ranges from 8 to 14 inches. Bats will mate in fall or winter and the pups are usually weaned in July or August. A few bat species will migrate to the south when cold weather approaches while other species will just move to trees, caves, mines and attics where the temperature does not go below the freezing point. In some cases, the big brown bat will even roost in buildings throughout the winter if conditions are favorable, e.g. high humidity level and temperature above the freezing point. Bats are loyal to their birthplaces, often returning to the same roost site year after year. A bat can live up to 30 years. There are more than 1100 different species in the world 46 species here in North America alone. And they account for about 1/4th of the world's mammal population.
Bed bugs

Bed bugs were once a common public health pest worldwide, which declined in incidence through the mid 20th century. Recently however, bed bugs have undergone a dramatic resurgence and worldwide there are reports of increasing numbers of infestations. Bed bugs are one of the great travelers of the world and are readily transported via luggage, clothing, bedding and furniture. As such, they have a worldwide distribution.

Birds are bipedal, warm blooded, oviparous veretbrate animals characterized primarily by feathers, forelimbs, modified as wings and in most hollow bones. Birds feed on nectar, plants, seeds, insects, fish, mammals, carrion, or other birds. Most birds are diurnal and many of them migrate a long distances to utilize optimum habitats.

Bees (Apoidea superfamily) are flying insects, closely related to wasps and ants. They are adapted for feeding on nectar, and play an important role in pollinating flowering plants, and are called pollinators. Bees have a long proboscis that they use in order to obtain the nectar from flowers. Bees have antennae made up of thirteen segments in males and twelve in females. They have two pairs of wings, the back pair being the smaller of the two.
Carpenter Ants

Carpenter ants are large, black ants (1/4" - 1") indigenous to large parts of North America. They also appear in northeast China. They prefer dead, damp wood to build nests in.

Crickets, family Gryllidae (also known as 'true crickets'), are insects related to grasshoppers and katydids (order Orthoptera). They have somewhat flattened bodies and long antennae. Crickets are known for the loud chirping noises they make by rubbing their wings over each other. Only male crickets sing as the male wings have ridges that act like a "comb and file" that produces a song that is species specific

Centipedes (Class Chilopoda) are fast-moving venomous, predatory terrestrial arthropods that have long bodies and many jointed legs. Chiefly nocturnal, centipedes are found primarily in tropical climates. Like the closely related millipedes, they are highly segmented (15 to 173 segments), with one pair of walking legs per segment. Centipedes are dorso-ventrally flattened, and are among the fastest and most agile of arthropod predators.

Flea is the common name for any of the small wingless insects of the order Siphonaptera. Fleas are external parasites, living off the blood of mammals and birds.

Name commonly used for any of a variety of winged insects, but properly restricted to members of the order Diptera, the true flies, which includes the housefly, gnat, midge, mosquito, and tsetse fly. All have sucking or piercing-and-sucking mouthparts and, except for a few wingless species, bear one pair of wings. The hind wings are reduced to knobbed balancing organs called halteres. All flies undergo complete metamorphosis, i.e., a four-stage development. The larvae, which occupy a wide variety of ecological niches, typically require a moist environment such as rotting flesh, decaying fruit, or the internal organs of other animals (see blowfly; botfly; fruit fly; tachinid fly). Adults often feed on nectar and plant sap, but some, such as the female horsefly and female mosquito, feed on blood; the adults of some species do not feed at all. A few species are found worldwide, often dispersed by humans; more than 16,000 species are found in North America. Many flies are harmful either as carriers of disease or as destroyers of crops. Some parasitize harmful insects. Some, such as the fruit fly, are important in laboratory studies. Flies are classified in the phylum Arthropoda, class Insecta, order Diptera.

The name gnat is applied to small insects in the order Diptera (the true Flies) and specifically within the suborder Nematocera. This suborder represents the more primitive members of the Dipteran order but still contains several very notable and important families such as the Chironomidae (non-biting midges) and the Culicidae (mosquitoes).

The Groundhog (Marmota monax), also called a Woodchuck or Whistle Pig, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. Most marmots live in rocky and mountainous areas, but the Woodchuck is a creature of the lowlands. It is widely distributed in North America, from Alaska to Alabama and Georgia. In the western United States it is found only in Alaska and northern Washington

Droppings, fresh gnaw marks, and tracks indicate areas where mice are active. Mouse nests are made from fine shredded paper or other fibrous material, usually in sheltered locations. House mice have a characteristic musky odor that identifies their presence. Mice are active mostly at night, but they can be seen occasionally during daylight hours.

Millipedes (Class Diplopoda, previously also known as Chilognatha) are very elongated arthropods with cylindrical bodies that have two pairs of legs for each one of their 20 to 100 or more body segments. These animals are herbivorous, slow and non - venomous; unlike the somewhat similar and closely related centipedes (Class Chilopoda), which can be easily distinguished by their single pair of legs for each body segment.

Light gray in color, opossums have five toes on each foot and a tail with no fur ... Opossums like to eat garbage, fruit, vegetables, green plants, insects.
Pavement ants

The pavement ant is a small, brown to black ant with pale legs and a black abdomen. Pavement ants feed on a variety of materials, including live and dead insects, honeydew from aphids, meats, grease, etc. They often enter houses looking for food. They may become numerous in a short period of time in a kitchen or outside on a patio.

Nocturnal new world mammal of the genus Procyon. The common raccoon of North America, Procyon lotor, also called coon, is found from S Canada to South America, except in parts of the Rocky Mts. and in deserts. It has a stocky, heavily furred body, a pointed face, hand like forepaws, and a bushy tail. It is 11/2 to 21/2 ft (46–76 cm) long, excluding the 8 to 12 in. (20–30 cm) tail, with mixed gray, brown, and black hair, a black facemask, and black rings on the tail. It lives mostly in wooded areas and usually feeds along lakes and streams

A rat is a small nearly omnivorous rodent of the genus Rattus which comprises 56 different species of what is commonly known as the Old World Rats or true rats who originated in Asia. Rats are bigger than their relatives the mice, but seldom weigh over 500 grams.

Any of numerous oval, flat-bodied insects of the family Blattidae, including several species that are common household pests.

Skunk, name for several related New World mammals of the weasel family, characterized by their conspicuous black and white markings and use of a strong, highly offensive odor for defense. The scent glands of skunks produce an oily, yellowish liquid, which the animal squirts with great force from vents under the tail; this produces a fine mist which, in addition to stinking, causes choking and tearing of the eyes. Skunks do not make use of this weapon unless severely provoked and then only after raising the tail in a warning display.

Common name for primitive, wingless insects of the family Lepismatidae. The silverfish, which has two long antennae and three long tail bristles, is named for its covering of tiny, silvery scales. It develops directly in six or more molts into an adult about 1/2 in. (1.27 cm) long. It has chewing mouthparts set in a head cavity and eats starch from bookbindings, wallpaper, and clothing. The silverfish is common indoors in cool, damp places such as basements. The firebrat, in the same taxonomic family, is found in warm places, e.g., near steampipes and boilers. Silverfish are classified in the phylum Arthropoda, class Insecta, order Thysanura, family Lepismatidae.

Name for a terrestrial gastropod mollusk in which the characteristic molluscan shell is reduced to a thin plate embedded in the tissues. Like the terrestrial snails of the same order, slugs have a distinct head with a mouth, tentacles bearing eyes, and a lung for breathing air. They move on a muscular foot over a trail of slime, which they secrete. Certain species, such as Limax maximus, have become serious pests in gardens and truck farms, particularly in the W United States. Gliding out to feed at night, they devour both the roots and aerial portions of plants with their rasp like radula. Terrestrial slugs are classified in the phylum Mollusca, class Gastropoda, order Stylommatophora

The name snail applies to most members of the molluscan class Gastropoda that have coiled shells. Other gastropods, which lack a conspicuous shell, are commonly called slugs, and are scattered throughout groups that primarily include snails. Snails are found in freshwater, marine, and terrestrial environments. While most people are familiar with only terrestrial snails, the majority of snails are not terrestrial.

Snakes are cylindrical in shape and do no have legs. They are cold blooded. Also they do not have eyelids or external ear openings. They are protected by a layer of scales. Each species of snake has a unique number of scales arranged and colored in a pattern on their bodies which help to identify them. Because snakes grow throughout their lives, they must replace the outer layer of scales (skin), which does not grow, this process is known as shedding, a process which can take up to a week to complete. During the shedding process the snake is temporally blind. To shed its skin a snake will rub its head against a rock, tree or some rough object to loosen it's old skin and will slowly crawl forward, turning the old skin inside out.

Organism, mostly terrestrial, of the class Arachnida, order Araneae, with four pairs of legs and a two-part body consisting of a cephalothorax, or prosoma, and an unsegmented abdomen, or opisthosoma. The cephalothorax is covered by a shield, or carapace, and bears eight simple eyes. On the underside of the head (the cephalic part of the cephalothorax) are two pairs of appendages, the anterior pair called chelicerae and the second pair pedipalps, with which the spider captures and paralyzes its prey, injecting into it venom produced in the poison glands. The spider then liquefies the tissues of the prey with a digestive fluid and sucks this broth into its stomach where it may be stored in a digestive gland. Breathing is by means of tracheae (air tubes) or book lungs, or both.

Name for small or medium-sized rodents of the family Sciuridae, found throughout the world except in Australia, Madagascar, and the Polar Regions; it is applied especially to the tree-living species. Tree squirrels range from the size of a mouse to the size of a house cat and vary greatly in color; some Asian tree squirrels are brilliantly patterned. In addition to the tree squirrels, the family includes the ground squirrel, chipmunk, marmot, woodchuck, prairie dog, and flying squirrel.

Termites or white ant, common name for a soft-bodied social insect of the order Isoptera. Termites are easily distinguished from ants by comparison of the base of the abdomen, which is broadly joined to the thorax in termites; in ants, there is only a slender connection (petiole) joining these segments. In addition, the antennae of termites are beadlike or threadlike, while ant antennae are elbowed. Termites have chewing mouthparts. They feed chiefly on wood, from which they obtain cellulose. In primitive species cellulose is converted into various sugars by specialized gut protozoans and in the more highly evolved termites by specialized bacteria living symbiotically in the termite's digestive tract. Termites undergo gradual metamorphosis (see insect). The nearly 2,000 species are mostly tropical, and some build huge mounds to house their colonies. These mounds, up to 40 ft (12.2 m) high, are a characteristic feature of the landscape in parts of Africa and Australia.

Ticks is the common name for the small wingless arachnids that, along with mites, comprise the order Acarina. Ticks are external parasites, living off the blood of mammals, birds, and occasionally reptiles and amphibians

Wasp, common name applied to most species of hymenopteran insects, except bees and ants. Insects known as wasps include the sawflies, the parasitic wasps, and the stinging wasps, which are the best known. About 75,000 species of wasps are known, most of them parasitic.

Woodchucks are a common farm and garden pest. Their love for home-grown vegetables is well known - to the chagrin of those hoping to harvest what they have worked so hard to produce. Woodchucks are fairly large animals and are related to the squirrel family. Their diet is generally herbaceous. They will eat quite a variety of foods such as lettuce, spinach, green beans, peas, squash, zucchini and cucumbers. They are known to eat berries as well.
