Color: Clear, Bright Red, Dark brown
Length: 1/32 Size of a speck of dirt
Habitat: Rat Nests and Bird Nests
 Reproduction: An interesting fact about mites is they can reproduce parthanogenetically but without fertilization they will only produce males. Females lay up to one hundred eggs in or near the nest that will hatch in one to two days. Females can start reproducing as early as two weeks after hatching.

  Misc: Mites are nocturnal and feed at night. They will feed on animals and humans when rats and birds have left the nest. They can survive up to fourteen days without their host.

A biting insect inspection should always consist of a rat and bird inspection. The use of monitors to properly identify the insect is recommended. The technician will need to go into the attic and crawlspace to remove nests. Pesticides rarely work on mites due to their size and habits. To eliminate a mite problem the technician will need to do a complete home inspection including crawlspace and attic. Set up a plan to remove the host and the nest. Then to prevent this problem from happening again the technician needs to seal up all openings the hosts were using to gain entrance into the home. 
When rats or birds are nesting in the attic mites will use power cords that lead into plug outlets to gain entrance to living spaces below. Depending on the construction of the home mites can also gain entrance through trim and baseboards. When rats  nest in the crawlspace mites can use utility lines running into the structure to gain entrance. An example of a prime location is the gap around the drain pipe underneath the sink. Normally the nest will be directly below or directly above the location where the bites take place. Mites do not transmit disease although no reports have been made precaution is always suggested.
Females, children, pregnant women and people with a high metabolism are most affected by bites because they produce more carbon dioxide. All blood feeders will seek out heat and carbon dioxide. The presence of these two elements tell the blood feeder that there a meal nearby. The more carbon dioxide the better the meal.
