Four parasitoid wasp species in one release, covering nearly every aphid species you're likely to find. You don't need to identify what you have. Release weekly until the aphids are gone, then taper off.
Generalist predator that takes aphids plus thrips, whitefly, and mites.
Thrips
Start here
Amblyseius cucumeris
Hang the sachets on the plants and they release predator mites continuously for 4 to 6 weeks. The mites attack thrips on the leaves before they reach the soil. Easiest deployment for almost every thrips situation.
Soil drench that kills the pupal stage in growing media. Pair with a leaf predator for full-cycle control.
Spider mites, broad mites & russet mites
Start here
Neoseiulus californicus
Handles spider mites, broad mites, and russet mites with one product. Survives between meals so it works for prevention as well as active outbreaks. The right starting point unless you've confirmed a heavy two-spotted spider mite outbreak.
Useful when thrips and mites are both present, since one product handles both.
Whiteflies
Start here
Encarsia + Eretmocerus Mix Cards
Hang cards on the plants. Both parasitoid wasp species emerge from the cards over several days, covering both greenhouse whitefly and silverleaf whitefly. You don't need to identify which species you have.
Same dual-species program, gradual-release blister format.
Fungus gnats
Start here
Stratiolaelaps scimitus
Sprinkle on the top half-inch of growing media and the predatory mites establish a permanent population in the soil. One application lasts for the life of the medium. Eats fungus gnat larvae and thrips pupae.
Targets cutworms and larger soil-dwelling larvae. Useful when multiple soil pests are present.
Caterpillars & grubs
Start here
Trichogramma minutum
Tiny parasitoid wasps that destroy caterpillar and borer eggs before they hatch. Release weekly for ongoing prevention. The right strain for eastern and central US growers. Western US growers should call us about T. platneri instead.
Weevil specialist for cooler soils, works down to 41°F.
Mealybugs
Start here
Cryptolaemus montrouzieri
The Mealybug Destroyer beetle. Both adults and larvae feed on mealybugs. Release once you can see clusters in leaf joints. Works best in enclosed spaces like grow tents and greenhouses.
Tiny parasitic wasps that lay eggs in fly pupae before adult flies can emerge. Apply to manure piles and bedding. Weekly releases through fly season prevent the next generation from hatching.
If you're not sure what's eating your plants, or which release size fits your space, talk to a real grower before you order. We've been doing this since 2006.
Or email help@happyhydro.com. We answer Monday through Friday, 10 am to 4 pm EST.
