Four Ways to Ruin an Aphid's Day

Ladybugs, lacewing larvae, Aphidius wasps and Aphidoletes midges are not four strengths of the same thing. Three of them arrive, work and are finished. One of them leaves a next generation inside the colony, which is the difference that decides most cases.

Beneficials Aren't OMRI Listed. That's The Point.

Go looking for an OMRI seal on a tube of predatory mites and you will not find one — on ours or on anybody's.

Thrips Never Seem To Go Away

Seven Ways To Waste Your First Mite Release

Nearly all of these are decisions rather than products, which is the good news: a decision can be made differently next time. The most expensive one is buying a second lot to fix a first lot, when the room was the problem both times.

Roll Your Swirskii Bottle Before You Open It
