About Clover Mite
Clover mites (Bryobia praetiosa) are 0.75 mm arachnids (not true insects) that appear bright red and have distinctively elongated front legs. They feed on over 200 plant species including turf grass and ornamentals, causing silvery stippling on leaf surfaces at high densities. In spring and autumn, enormous numbers migrate up building walls and enter homes through any tiny gap — windowsills, door frames, and weep holes. They do not bite humans or pets, but crushing them leaves red stains on walls and surfaces. Creating a vegetation-free barrier zone around the building perimeter is the most effective prevention.
Geographic Distribution
This insect is found across South America, with notable populations in Argentina and surrounding regions.
