Got Thrips or Whiteflies? This Is the Treatment That Doesn’t Wait.

Mite Matters
The Hidden Toll of Thrips on Plant Health
How Predatory Mites Use Chemical Signals
Predatory mites don’t just hunt—they communicate. Plants call for backup with chemical signals, predators leave scent trails, and entire ecosystems shift in response. These invisible conversations shape how pests are controlled, long before you see results on the leaves.
