Argentine Ant
Argetine ants The worker ants are 1.6–2.8 millimetres (0.06–0.11 in) long and can easily squeeze through cracks and holes as small as 1 millimetre (0.04 in) in size. Queens are 4.2–6.4 millimetres (0.17–0.25 in) long, much smaller than other species of ants. These ants will set up quarters in the ground, in cracks in concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily take over the space
Black Widow
These small spiders have an unusually potent venom containing the neurotoxin latrotoxin, which causes the condition latrodectism, both named after the genus. Female widow spiders have unusually large venom glands and their bite can be particularly harmful to large vertebrates, including humans. Only the bites of the females are dangerous to humans. Despite their notoriety, Latrodectus bites rarely cause death or produce serious complications.
Box Elder Beetle
The boxelder 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.
Brown Dog Tick
Brown dog tick, kennel tick, or pantropical dog tick, is a species of tick found worldwide, but more commonly in warmer climates. This species is unusual among ticks in that its entire lifecycle can be completed indoors. The brown dog tick is easily recognized by its reddish-brown color, elongated body shape. The tick follows the normal developmental stages of egg, larva, nymph, and adult. It is called a three-host tick because it feeds on a different host during each of the larval, nymphal, and adult stages. However, the hosts tend to be of one species. Larvae feed for 5-15 days, drop from the host, and develop into nymphs after 1-2 weeks. The nymphs then attach to either the previous host or a different host and feed for 3-13 days before dropping from the host. After two weeks, they develop into adults and attach to another host where they continue to ingest blood, followed by a period of mating. The females drop yet again in order to lay their eggs, which can total up to 7,000 in number.
Fleas
Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that survive as external parasites of mammals and birds. Fleas live by consuming blood, or hematophagy, from their hosts. Adult fleas grow to about 3 mm (0.12 in) long, are usually brown, and have bodies that are “flattened” sideways or narrow, enabling them to move through their host’s fur or feathers.
German Cockroach
The German cockroach occurs widely in human buildings, but is particularly associated with restaurants, food processing facilities, hotels, and institutional establishments such as nursing homes. In cold climates, they occur only near human dwellings, because they cannot survive severe cold. Though they would soon die in the outdoors on their own, German cockroaches have been found as inquilines (“tenants”) of human buildings. The German cockroach reproduces faster than any other residential cockroach, growing from egg to reproductive adult in roughly 50 – 60 days.
Indian Meal Moth
Indian-meal moth larvae can infest a wide range of dry foodstuffs of vegetable origin, such as cereal, bread, pasta, rice, couscous, flour, spices, dried fruits, and nuts. More unusual recorded foods include crushed red pepper, chocolate and cocoa beans, coffee substitute, cookies, dried mangelwurzel, and even the toxic seeds of jimsonweed (Datura stramonium). They have also been known to infest commercial pet food, such as cracked corn used for bird feed. They often leave webbing in the food they infest After larvae or moths have been found, it is important to throw out all food sources not in very tightly sealed containers. Moth larvae can chew through plastic bags and thin cardboard, so even unopened packages may become infested. They are also notoriously difficult to get rid of, and can crawl on ceilings and spin cocoons in rooms other than the kitchen or pantry where they hatched.
Mouse
A mouse, plural mice, is a small rodent characteristically having a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse. Mice are largely herbivores, consuming any kind of fruit or grain from plants. However, mice adapt well to urban areas and are known for eating almost all types of food scraps.
Odorous House Ant
The odorous house ant is tough: Injured workers have been observed to continue living and working with little hindrance, some queens with crushed abdomens still lay eggs, and there are documented instances of T. sessile queens surviving without food or water for over two months. They also appear highly tolerant to heat and cold. These ants are difficult to remove from a home after their colony has become well-established. When offered a choice of food sources, the ants preferred sugar and protein over lipids, and this preference persisted in all seasons. When specific sugar sources were studied the ants preferred sucrose over other sugars, such as fructose or glucose.
Oriental Roach
Oriental cockroaches tend to travel somewhat more slowly than other species. They are often called “waterbugs” since they prefer dark, moist places. They can often be found around decaying organic matter, and in sewers, drains, damp basements, porches, and other damp locations. They can be found outside in bushes, under leaf groundcover, under mulch, and around other damp places outdoors.
Paper Wasp
Paper wasps are vespid wasps that gather fibers from dead wood and plant stems, which they mix with saliva, and use to construct water-resistant nests made of gray or brown papery material. Some types of paper wasps are also sometimes called umbrella wasps, due to the distinctive design of their nests
Rice Weevil
Adult rice weevils are able to fly, and can live for up to two years. Females lay 2-6 eggs per day and up to 300 over their lifetime. The female uses strong mandibles to chew a hole into a grain kernel after which she deposits a single egg within the hole, sealing it with secretions from her ovipositor. The larva develops within the grain, hollowing it out while feeding. It then pupates within the grain kernel and emerges 2–4 days after eclosion.
Roof Rat
Roof rat typical adult black rat is 12.75 to 18.25 cm (5.0 to 7.2 in) long, not including a 15 to 22 cm (5.9 to 8.7 in) tail, and weighs 75 to 230 g (2.6 to 8.1 oz), depending on the subspecies. Despite its name, the black rat exhibits several colour forms. It is usually black to light brown in colour with a lighter underside. Black rats are considered omnivores and eat a wide range of foods, including seeds, fruit, stems, leaves, fungi, and a variety of invertebrates and vertebrates. They are generalists, and thus not very specific in their food preferences, which is indicated by their tendency to feed on any meal provided for cows, swine, chickens, cats, and dogs. They are similar to the tree squirrel in their preference of fruits and nuts. They eat about 15 grams (0.53 oz) per day and drink about 15 millilitres (0.53 imp fl oz; 0.51 US fl oz) per day.
Turkestan Cockroach
Turkestan cockroach primarily an outdoor insect, not known as an aggressive indoor pest, unlike some cockroach species such as the German and brown-banded cockroaches, though it will inhabit areas around dwellings where shelter can be found. However, in specific localities or tropical locations, it can become a significant indoor pest. Of occasional indoor interlopers, males are more commonly encountered than females, due to their ability to fly and an attraction to lights.
