- Color: brown to olive-green.
- Size: adults are about 1/64 inch long.
- Body shape is similar to that of ticks.
- Adults and nymphs have eight legs.
- Very long front legs, I. e., longer than the body and twice as long as any of the other legs.
- Younger stages are bright red, as are the smooth, round eggs.
Clover Mites Habits:
- Females are parthenogenetic, i.e., laying eggs without fertilization by a male.
- Eggs are deposited in the fall in protected locations on building foundations, and under the bark of trees and do not hatch unless the temperature is between 40 and 70 F.
- Developmental time (egg to adult): from one to seven months.
- They are plant feeders which infest more than 200 different plants.
- They overwinter as adults, immatures, or eggs. They build up very large populations around houses surrounded with lush, well-fertilized lawns and shrubbery.
- They often move into houses in tremendous numbers in the autumn when vegetation begins to die.
- In the spring, large numbers indoors is usually the result of recent mulching and onset of higher temperatures. Large populations of clover mites occurring on the roofs of houses are associated with moss growth, especially cedar shake shingles.
Damage From Clover Mites:
- Clover mites are harmless but are a great annoyance to building occupants.
- If crushed, they leave a red stain on walls, floors, and furnishings.
- Mites crawling in long trails on the inside of exterior walls, window and door frames.
How to Control Clover Mites:
- Infestations in the home should be controlled using mechanical control measures such as a vacuum cleaner.
- Residual or aerosol pesticide applications indoors does little to solve the problem and are not recommended.
- To prevent clover mite invasions, lush vegetation within an 18 – 24 inch band around the house perimeter should be removed.
