They lay their eggs inside whitefly larvae, biologically interrupting infestations on vegetables, herbs, and ornamental plants. They are particularly suitable for greenhouses and indoor spaces and are harmless to humans and pets.\u003c\/p\u003e\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eThe white cloud under the leaf\u003c\/h2\u003e\n\u003cp\u003eYou brush past your tomato plant, and suddenly a small white cloud rises. Whiteflies, also known as glasshouse whiteflies, prefer to sit on the undersides of leaves, where they suck plant sap. In the process, they excrete honeydew, a sticky substance that often attracts sooty mold fungi. The leaves become sticky, and the plant weakens. And because these insects thrive in stagnant air, a few flies can quickly turn into a massive infestation.\u003c\/p\u003e\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eShould you use Eretmocerus or Encarsia against whiteflies?\u003c\/h2\u003e\n\u003cp\u003eEncarsia parasitic wasps are primarily targeted at the greenhouse whitefly (Trialeurodes vaporariorum), though they can partially control the tobacco whitefly (Bemisia tabaci). They are active at temperatures as low as 13 °C, making them well-suited for greenhouses, houseplants, and indoor growing. For tobacco whitefly and consistently warm conditions between approximately 20 and 30 °C, we offer Eretmocerus as a secondary parasitic wasp in our whitefly control range.\u003c\/p\u003e\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003ePowerful against whiteflies? Encarsia parasitic wasps!\u003c\/h2\u003e\n\u003cp\u003eEncarsia formosa are only about 0.6 mm in size. You hang the carrier cards with the Encarsia pupae directly on the infested plants; after 5–10 days, the parasitic wasps hatch and lay their eggs in the whitefly larvae or suck them out. New parasitic wasps develop from the parasitized larvae, and the cycle continues on its own. A visible reduction in infestation is usually seen after 2–3 weeks. Once no more whiteflies are present, the beneficial insects disappear without a trace. They do not sting, hardly fly at all, and are harmless to humans and pets.\u003c\/p\u003e\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eBuy Encarsia parasitic wasps against whitefly online\u003c\/h2\u003e\n\u003cp\u003eYou order by area, from one card for 2 m² up to 25 cards for 50 m². The beneficial insects come from German breeding programs and are shipped as live goods; specific shipping instructions are provided for hot and cold days. Depending on the level of infestation, we recommend 1–3 applications at intervals of 1–2 weeks. For even more thorough results, combine Encarsia with our nematodes against whitefly and hang up yellow sticky traps for monitoring. Because our range is organized by target pest, you can find everything you need to combat whitefly in one place.\u003c\/p\u003e\n\u003ch3 style=\"color: #305832; font-size: 18px; font-weight: bold; margin-top: 32px;\"\u003eWhen are Encarsia parasitic wasps the right choice?\u003c\/h3\u003e\n\u003cp\u003eChoose Encarsia if you have whiteflies on tomatoes, cucumbers, peppers, herbs, or ornamental plants in the greenhouse or home and want to take action without chemicals. They are ideal for greenhouse whitefly in temperatures from about 13 °C and with sufficient light. They work best when applied at the very first sign of flies, before the infestation can multiply significantly.\u003c\/p\u003e\n\u003ch3 style=\"color: #305832; font-size: 18px; font-weight: bold; margin-top: 32px;\"\u003eWhen are Encarsia parasitic wasps not the right solution?\u003c\/h3\u003e\n\u003cp\u003eWe do not recommend Encarsia for outdoor use, as the beneficial insects require a stable climate and sufficient light. In winter, supplemental lighting of at least 5,000 lux is necessary in the event of low light. For tobacco whitefly and consistently warm conditions, our Eretmocerus parasitic wasps are the more suitable choice. If you are looking for an overnight solution, you will need some patience, as visible results usually appear after two to three weeks. Synthetic pesticides are off-limits for at least six weeks before and after application.\u003c\/p\u003e\n\u003cdiv style=\"background-color: #e2f1e2; padding: 16px; border-left: 4px solid #305832; border-radius: 8px; margin-top: 24px;\"\u003e\n\u003cp style=\"margin: 0; color: #2d3a2e;\"\u003e🌿 \u003cstrong\u003eConclusion:\u003c\/strong\u003e GREEN GUARDIA Encarsia parasitic wasps are a biological, residue-free solution against whiteflies, especially in greenhouses and indoors.
