svg{flex-shrink:0;} Stop cabbage worms and corn borers before the eggs hatch Cole crops and vegetable gardens draw a steady stream of egg-laying moths, and once the caterpillars hatch the damage is done. Trichogramma brassicae attacks earlier, parasitizing moth and butterfly eggs before they hatch. It is especially effective in cole crops and cool-climate plantings and targets over 200 species of moths and butterflies, including cabbage worms, loopers, borers, and armyworms. Release the cards weekly during moth flights. Stops pests at the egg stage Covers 200+ moth and butterfly species Ships live, overnight Tuesdays Live insects ship on Tuesdays only and arrive Wednesday. Orders must be placed 7 days in advance. Anything ordered by 3pm EST Tuesday ships the following Tuesday by UPS overnight shipping. UPS overnight shipping on live insects Bundle and save on shipping 5% off with subscription Why it's different Fighting caterpillars vs. destroying their eggs Caterpillar sprays You react after caterpillars are chewing Big caterpillars shrug off many sprays Sprays coat crops and need harvest timing Broad products hit butterflies and beneficials One-time sprays leave gaps Labor-heavy and reactive Trichogramma brassicae Destroys the eggs before a caterpillar hatches The pest is stopped at its weakest stage No spray, no residue, no re-entry interval Wasps target moth and butterfly eggs, sparing the crop Weekly cards give continuous egg-stage coverage Hang a card and the wasps patrol for you What makes it work Why egg-stage control wins in the garden Kills pests before they hatch Egg-stage control Female wasps lay inside pest moth eggs, and the developing wasp consumes the contents, so no caterpillar ever emerges to feed on your crop. Covers 200+ species Brassicae parasitizes the eggs of more than 200 moth and butterfly species, including cabbage worms, loopers, borers, fruitworms, hornworms, and armyworms. Suited to cole crops It is especially effective in cole crops and cool-climate plantings, making it a strong fit for vegetable gardens growing cabbage, broccoli, and their relatives. Built for a weekly program Because moths keep laying, the best results come from releasing cards weekly during the flight period so fresh wasps meet fresh eggs. Wasps keep cycling Adults emerge from the cards in days and search out more pest eggs, extending each release beyond the moment you hang it. Low-effort to deploy The cards clip onto plants with no mixing or equipment, so weekly prevention stays low-effort. What it targets Pest species it targets European corn borer Cabbage loopers Armyworms Cutworms Tent caterpillars Diamondback moth Fruitworms Leafrollers and many more Ideal conditions Where it works best Temperature Effective 50-95°F; optimal 68-81°F Humidity Around 60% RH Best crops Cole crops and cool-climate plantings Program Weekly during moth flights How to apply Application instructions 1 Hang or clip the cards in the canopy across the crop. 2 Release during moth activity; wasps emerge in 2-5 days (fastest at 80-90°F). 3 Typical rate 1-2 per sq ft, or 50,000-100,000 per acre weekly. 4 Release in the morning and don't delay once the wasps emerge. How brassicae stops the next caterpillar 1 Hang the cards Clip the release cards onto plants across your crop, spaced fairly evenly through the canopy. 2 Wasps emerge in days Adult Trichogramma hatch from the parasitized eggs on the card and begin searching for pest eggs. 3 They parasitize pest eggs Each female lays inside moth and butterfly eggs, which darken as the wasp develops instead of a caterpillar. 4 Repeat weekly Because moths keep laying, hang fresh cards each week during the flight period to keep steady coverage. In the package What you get and how to size it What ships to you Trichogramma brassicae release cards with parasitized host eggs Count matched to your chosen size Hanging and weekly release instructions Insulated overnight packaging Sizes and options Card counts: sized to your crop area Program: weekly releases during moth activity Different strain needed? ask us about minutum or platneri for your region Which Trichogramma strain fits me? Brassicae is well suited to cole crops and cool-climate plantings. Minutum suits eastern and central US growers broadly, and platneri is the western US strain. Tell us your crop and region and we will match it. Call or email us: 716-217-0353 / [email protected] Questions Frequently asked questions How is brassicae different from the other Trichogramma strains? All the Trichogramma strains parasitize moth and butterfly eggs, but they are matched to different crops and regions. Brassicae is especially effective in cole crops and cool-climate plantings. Minutum is the broad eastern and central US strain, and platneri is adapted to the western US. We can help you pick the right one for your situation. How do I know it is working? Parasitized pest eggs darken to brown or black as the wasp develops inside, which is your visible confirmation. The bigger signal is what you stop seeing: fewer new caterpillars and less fresh chewing damage over the following weeks. Will these wasps sting me or harm my plants? No. Trichogramma are among the smallest insects in the world and are harmless to people, pets, and plants. They are interested only in the eggs of moths and butterflies. When do these ship and when should I release? Live insects ship overnight on Tuesdays only, so they arrive Wednesday while still fresh. Place your order at least 7 days ahead so we can include you in the next weekly dispatch. We cannot ship live insects to HI, PR, VI, GU, AS, or PW. Open the package and release the same day it arrives. What if my order arrives damaged or the insects are dead on arrival? If you receive a defective or damaged unit, email us a photo at [email protected] and we'll make it right immediately. For change-of-mind returns, we accept returns within 30 days for items in new, resalable condition. If you're not sure whether this product is right for your setup, call us first at 716-217-0353.
