Concrete mite

Commonly found on sun-exposed hard surfaces such as concrete walls, sidewalks, and masonry, especially during the spring and summer.

They mainly feed on pollen and may also scavenge on smaller, soft-bodied insects and their eggs.

They are highly active crawlers, often seen moving rapidly over warm surfaces. They have a short lifespan and are most prevalent when environmental conditions are warm and dry.

They are harmless to humans and structures, though they may leave a small red stain if crushed. Ecologically, they help control microscopic pests and assist in the breakdown of organic matter.
