The adult bedbug is 3/16 inch long and a rusty-red color. The bedbug is flat and thin when unfed but becomes more plump and red when it is engorged with blood.
They hide in cracks and crevices during the day, preferring to rest on wood and paper surfaces. Then leave these areas at night to feed on its host which may include humans, birds, and family pets. The blood meal requires three to 10 minutes and usually go unnoticed by the victim. The bite site may become inflamed and in sensitive individuals, itch severely.
Although the bedbug has been associated with more than 25 diseases, transmission has not been proven.
Mosquitoes are members of the order Diptera (flies). They are slender, long legged, two winged insects from 1/8 to 1/4 inch long and are usually dark in color. Unlike other flies, their wings and bodies are covered with scales, and they have long piercing/sucking mouthparts.
Females lay their eggs on damp soil in areas that are infrequently flooded. If submerged immediately after having been laid, the eggs hatch within four or five days.
These vicious biters feed on humans and other animals night and day and are a problem, especially in areas where crops are irrigated. They are attracted to light and can make life very uncomfortable for individuals who work and play outdoors.
Ticks can be 1/8 to 5/8 inch long, and are an orangish-brown color except for the dark reddish brown head, shield behind the head, and legs. Their bodies are flattened and shaped like a teardrop.
Ticks are concentrated in transition areas between fields and lower grassy vegetation, along animal trails, and in host-animal nests and dens, such as woodpiles, burrows in the ground, stumps, logs, old rat and bird nests, and crawlspaces. They can carry and transmit diseases.
A flea is a minuscule, wingless parasites about 1/8 of an inch long, or equivalent to the size of a poppyseed. They are covered in spines with piercing mouthparts and are extremely difficult to crush.
They live and breed on their host animal and can jump 6 to 8 inches vertically, and 14 to 6 inches horizontally.
