Mites Tetranychus urticae & clover mites

Spider mites are the specks that turn plant leaves stippled and dusty, spinning fine webbing when the colony matures — worst in hot, dry, sheltered spots. The tiny red dots marching on the windowsill are clover mites: harmless, but they smear crimson when wiped.

Signs you have them

  • Stippled, bleached leaves with fine webbing underneath
  • Dusty specks that move when you tap a leaf over paper
  • Tiny red dots on sills and sunny walls in spring

What you can do today, free

  • Hose plant undersides hard, twice a week — mites hate humidity and force
  • Don’t broad-spray insecticide: it kills the mites’ predators first and makes it worse
  • Vacuum clover mites off sills rather than wiping (stains)

Questions, answered straight

Are these the mites that bite people?

Spider and clover mites don’t bite humans. If you’re getting bitten, that’s a different conversation — rodent or bird mites from a nest — and finding that nest is a Pest Plan visit.
