Clover mites can become annoying
household pests, especially in and around homes where new lawns
are being established or where there’s a heavy growth of
well-fertilized grass close to foundation walls.
Clover mites feed on grasses,
clovers and certain other plants in the lawn and around the home.
They often crawl into cracks and crevices to molt and lay eggs.
places” are under the loose bark of trees, on foundations
walls, beneath siding and around window frames.
Clover mites are
most abundant in the fall and spring and are relatively inactive
during the hot summer months and again during cold weather. They
migrate into homes either when population pressure becomes too
great or when feeding conditions become unfavorable, such as the
onset of hot or cold weather.
The mites are very tiny creatures (smaller than
a pin head) and may occur in countless numbers. They usually appear
first around windows, but later may overrun the entire home. They
do not bite people nor cause any damage indoors, but are extremely
annoying and may leave a red stain when crushed.
