Clues to the type of host that has invaded the house can be deduced by the time of year that the mite infestation occurs. Rodent infestations are possible at any time of year, though they seem to occur most frequently in the fall and winter. Bird problems are most common during the spring and summer. Roof rats are the most common rat encountered in Texas homes.

As their name implies, roof rats are good climbers and often enter the home through openings in the roof or soffit areas. Noises in attic or ceilings, especially at night, can indicate roof rat activity. To seal homes against rodents all vents and electric service entry points should be tightly closed with rodent-proof metal hardware cloth, metal flashing, or copper wool. Entry points around chimneys and between loose shingles should also be checked.

Doors and windows should seal tightly. House mice will enter structures near the ground, especially under poorly-sealed doors. Rodent proofing must include the smallest entry holes. Mice can enter a home through a hole as small as a dime; rats can enter through a hole as small as a quarter. Bird infestations are often first indicated by the sound of chirping coming from a chimney or soffit area.

Special screening may be needed on chimneys to deny birds access to chimney areas. Birds nesting in chimneys may also indicate the need for chimney maintenance and cleaning. Chickens and other fowl kept in sheds or coops attached to a home can also be a source of mites indoors. Pesticides can help suppress mite populations in the home, but must be used in combination with bird or rodent control. Treatment for mites should be done concurrently with, or even before, rodent extermination to control mites before they disperse from previously occupied rodent nests.

Several pesticides can be used indoors to treat mite problems. Sprays and aerosols containing syngergized pyrethrins should kill mites immediately on contact, though the treatment will only remain effective for up to a few hours.
