Well these bugs are called mites more specifically clover mites.
Tiny bugs on concrete wall.
They are tiny black gnat like bugs but they crawl fast especially in the sunlight they actually act like ants.
What do clover mites eat.
Bugholes are found more frequently in the upper portion of the concrete structure or at angled form surfaces as a result of additive accumulation from escaping air voids along the height of the structure.
These surface voids are primarily an aesthetic problem for exposed structural concrete.
I noticed them at a rate of maybe 10 or so per square meter.
Clover mites lay less producing only about 70 eggs but these pests are parthenogenetic meaning that eggs do not need to be fertilized.
They don t seem to fly.
Mites on concrete female spider mites begin to produce eggs after mating and can have as many as 300 over a fortnight.
Clover mites are an arachnid which makes them similar to spiders and ticks.
They are under 1 mm even with a magnifying glass you can t really make out details but you can see these tiny black spots marching.
There is a garden on one side of the patio in case that matters.
Have you ever wondered what those little tiny red bugs are that are usually found on concrete surfaces.
Some of these insects are attracted to damp areas of concrete such as in basements while others can be seen crawling over relatively dry concrete walls or on sidewalks.
They do not jump and their speed is about 1cm sec or so.
I detected some tiny insects wandering over my concrete.
Clover mites generally feed on grass weeds and other vegetation.
