Usually, 0.6 and 0.7mm in length soft, oval and flattened from top to bottom. They vary in colour from rusty brown to dark red, very long pair of front legs that extend forward as the mites crawl.
The female mite lays its eggs, bright red in colour, onto the bark of trees, rocks in the soil or on walls of buildings. The eggs generally overwinter and then in the spring the larvae and nymphs of the mite feed on plant material, sucking the fluid from the leaves. The life cycle can be extremely rapid in warmer parts of the country. A five-week life cycle is possible during optimum conditions
The mites do not bite man but nevertheless some form of remedial treatment may be necessary if they are occurring in sufficient numbers as to be a nuisance. If vegetation is to be treated then a pesticide approved for horticultural use for the control of mites on plants would be suitable to control this pest.
