Odorous Household Ants
This ant gets its name from the strong, rotten coconut-like smell it gives off when crushed. These tiny insects range in size from one-sixteenth of an inch to one-eighth of an inch long.
Habits
Odorous house ants like to eat sweets, especially melon.
Habitat
Typically living for several years, these ants make their homes in exposed soil and wall cracks.
Threats
These ants do not pose a public health risk, but they can contaminate food and should be avoided.
Carpenter Ants
Carpenter ants get their name because they excavate wood in order to build their nests. Their excavation results in smooth tunnels inside the wood. Carpenter ants range in size from one-quarter inch for a worker ant to up to three-quarters inch for a queen.
Habits
All species mainly attack wood that is or has been wet and damaged by mold. Even though these ants first invade wet, decayed wood, they may soon begin building paths through dry, undamaged wood. They usually come into buildings through cracks around doors, windows, or through holes for wires. They will also crawl along overhead wires, shrubs, or tree limbs that touch the building far above the ground.
Habitat
Carpenter ants build their nests outdoors in various wood sources, including tree stumps, firewood or landscaping. They need a constant water source to survive. They will enter homes through wet, damaged wood.
Threats
Carpenter ants damage wood through their nest building. If they gain entry to a structure, they pose a property threat.
Red Fire Ants
Red imported fire ants nest in soil and build mound nests. They can infest garages.
Habits
These ants will build large mound nests, and will sting humans who come across a nest.
Habitat
Red imported fire ants will build their nest mounds outdoors in landscape areas or near a structural foundation. The ant will gain entry to a building through holes or cracks.
Threats
The sting of a red imported fire ant is painful and often results in a raised welt that becomes a white pustule. Often, a person stung by a red imported fire ant receives multiple painful stings from more than one of the ants. Persons allergic to insect stings will react more severely.
Bed Bug
The common bed bug is a parasite which lives on the outside of the body of the host. Bed bugs feed only on the blood of humans and other warm-blooded hosts. Although they have a cryptic behavior and can conceal themselves in tight cracks and crevices, bed bugs are often found in bed parts, such as mattresses and box springs, hence the common name.
Habits Bed bugs like to travel and are good hitchhikers. They will hide in suitcases, boxes and shoes to be near a food supply. They are elusive, nocturnal creatures. They can hide behind baseboards and in cracks, crevices, and folded areas of beds, bedding and adjacent furniture, especially mattresses and box springs. Bed bugs can also hide in electrical switchplates, picture frames, wallpaper and nearly anywhere inside a home, car, bus, or other shelter. Bed bugs usually come out at night for a blood meal. However, they are opportunistic insects and can take a blood meal during the day, especially in heavily-infested areas. Bed bugs usually require 5-10 minutes to engorge with blood. After feeding, they move to secluded places and hide for 5-10 days. During this time, they do not feed but instead digest their meal, mate, and lay eggs.
Threats Bed bugs do not transmit diseases, but their bites can become red, itchy welts.
Cockroaches
The American cockroach is the largest of the house-infesting cockroach.
Habits
American cockroaches are found in food processing areas and food storage areas, as well as other types of buildings. They are active when the temperature is 70 degrees or higher, but they can survive lower temperatures with the right conditions.
Habitat
American cockroaches are often found in sewers and basements, particularly around pipes and drains.
Threats
Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Recent medical studies have shown that cockroach allergens cause lots of allergic reactions in inner city children. They were even shown to cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.
Flies
House flies get their name from being the most common fly found around homes. Adult house flies can grow to one-quarter of an inch long and usually live between 15 and 25 days.
Habits
They are only able to feed on liquids but have the ability to turn many solid foods into a liquid for them to eat. House flies taste with their feet, which are 10 million times more sensitive to sugar than the human tongue.
Habitat
House flies tend to stay within 1-2 miles of where they were born; however, they have been known to migrate up to 20 miles to find food.
Threats
These insects have been known to carry over 100 different kinds of disease-causing germs, which makes them very bad house guests.
Dust Mites
House dust mites have received much attention in the early 1990s and again recently. The house dust mite is nearly impossible to see without magnification and is named for the fact that they feed on dead skin shed by humans as well as other protein materials.
Habits
House dust mites feed on dander (dead skin which is shed) from humans and animals. They may also feed on protein based foodstuffs, preferring dried products over products with moisture. Females lay up to 80 eggs and there are several stages of immatures. Populations can explode during humid months as mites are excellent at absorbing moisture from the air.
Habitat
The most common area for finding mites is in the bed due to abundance of dander. House dust mites may also be found in living areas especially carpet, furniture, and clothing. Several home test kits are available to test for dust mites.
Threats
People may be allergic to house dust mite cast skins and droppings. These reactions will not be a rash type of reaction but rather a respiratory constriction, a common symptom of asthma. Itchy, watery eyes may also be symptoms. Approximately 50-80% of asthmatics may have symptoms due to house dust mites.
Mosquitoes
One of the best known summer pests, mosquitoes breed in stagnant water or soft soil and can develop from egg to adult in 10 to 14 days.
Habits
Female mosquitoes suck our blood. Male mosquitoes feed on plant nectars. They can develop from egg to adult in 10 to 14 days. They are most active from dusk to dawn and will fly up to 14 miles for a blood meal.
Habitat
Mosquitoes breed in stagnant water sources such as storm drains, old tires, children's wading pools and birdbaths.
Threats
Mosquitoes are well-known to spread diseases such as West Nile Virus, malaria and dengue fever.
Yellowjackets
There are several species of yellowjackets. These flying insects typically have a yellow and black head/face and patterned abdomen. Many say, the pattern resembles stripes. Signature to species, the abdomen pattern can help an entomologist or pest professional identify specific types of yellowjackets.
Habits
Yellowjackets nest in the ground or in cavernous areas such as eaves, attics, etc.... They feed on sweets and proteins and commonly invade outdoor activities.
Habitat
Yellowjackets can be found anyplace humans can be found. Check near recycling bins or other areas where sugars are common but keep in mind these pests also feed on protein. Yellowjackets become more aggressive in autumn when the colony begins to die out except for the queen.
Threats
Yellowjackets pose significant health threats to humans as they may sting repeatedly and can cause allergic reactions. Stinging insects send over 500,000 people to the emergency room each year.
Black Widow Spiders
Black widow spiders are most recognized for the red hourglass shape under their abdomen. Contrary to legend, female black widow spiders rarely devour the male black widow spider after mating.
Habits
Black widow spiders spin their webs near ground level. They often build their webs in protected areas, such as in boxes and in firewood.
Habitat
Black widow spiders are often found around wood piles and gain entry into a structure when firewood is carried into a building. They are also found under eaves, in boxes, and other areas where they are undisturbed.
Threats
The venom of a black widow spider is a neurotoxin and is used as a defense. Black widow spiders do not bite humans instinctively. The black widow spider bite can cause severe pain. Young children and the elderly are especially susceptible to a severe reaction to a black widow spider bite.
Brown Recluse Spiders
Brown recluse spiders have a characteristic dark brown violin marking on their back.
Habits
Brown recluse spiders are nocturnal and eat other bugs like cockroaches and crickets. Male brown recluse spiders wander farther than females and will crawl into shoes or other clothing.
Habitat
Brown recluse spiders often live outdoors in debris and wood piles. They can be found indoors in storage areas and dark recesses.
Threats
Like the black widow spider, the brown recluse spider bites in defense and does not bite humans instinctively. They will bite humans when the clothing they are hiding in is worn. The brown recluse spider bite is painful and can produce an open, ulcerating sore.
Subterranean Termites
Subterranean termites live in underground colonies or in moist secluded areas aboveground that can contain up to 2 million members. They build distinctive "mud tubes" to gain access to food sources and to protect themselves from open air. Termite colonies are organized into castes depending on tasks -- workers, soldiers and reproductives. The characteristics of a subterranean termite are dependent on the termite's role in the colony. Cream-colored Worker subterranean termites are 1/8 to 3/8's of an inch in length. Soldier subterranean termites are of a similar body length, but are distinguished by their powerful mandibles. Solider termites have cream-colored bodies and brown heads. Reproductive subterranean termites are approximately one inch long.
Habits
Subterranean termites live underground and build tunnels, referred to as mud tubes, to reach food sources. Like other termite species, they feed on products containing cellulose. Subterranean termites swarm in the spring -- groups of reproductive termites go off to start new colonies.
Habitat
FSubterranean termites need contact with the soil to survive and live underground. They can build tunnels through cracks in concrete.
Threats
Subterranean termites are by far the most destructive species. They can collapse a building entirely, meaning possible financial ruin for a homeowner. The hard, saw-toothed jaws of termites work like shears and are able to bite off extremely small fragments of wood, one piece at a time.
Formosan Termites
Originally from China, Formosan termites are the most voracious, aggressive and devious of over 2,000 termite species known to science. Formosan termites are a subterranean species of termite. Swarmer formosan termite are about 1/2 inch in overall length, including their wings.
Habits
Formosans are organized into huge underground colonies, and build intricate mud nests inside the walls of a structure.
Habitat
Formosan termites are the most aggressive subterranean termite species. Formosans are organized into huge underground colonies, and build intricate mud nests inside the walls of a structure.
Threats
Because of their aggressive nature, formosan termites are difficult to control once they infest a structure. Prevention is key.
