Once in the soil, they penetrate the flea beetle larvae and stop their development. They are a biological alternative to chemical pesticides and are harmless to humans, pets, and beneficial insects.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eCombating flea beetles: holes in leaves are only half the story\u003c\/h2\u003e\n\u003cp\u003eFlea beetles are small, shiny beetles that jump away at the slightest touch. They eat holes into the leaves of radishes, arugula, cabbage, and other cruciferous vegetables. For young plants and fresh seedlings, this is often enough to destroy a large portion of the crop. What many people don't know: the beetles lay their eggs in the soil, and the larvae continue to live there. This is where our nematodes come in, targeting the pests at the root.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eSF flea beetle nematodes for garden beds, raised beds, containers, and greenhouses\u003c\/h2\u003e\n\u003cp\u003eWherever you grow radishes, arugula, or types of cabbage, treating the soil is worthwhile. Whether in vegetable patches, raised beds, greenhouses, or balcony planters: simply add the SF nematodes for flea beetles to water and pour it carefully onto the soil. It is important that they reach the roots directly and do not land on the leaves.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eHow SF nematodes against flea beetles work in the soil\u003c\/h2\u003e\n\u003cp\u003eSteinernema feltiae lives in the soil and actively searches for prey there. SF nematodes against flea beetles penetrate the larvae and stop their development, preventing the next generation of beetles. Nothing is left on the leaves. The nematodes only move in moist soil, which must remain consistently damp before application and for at least 14 days afterward. They are harmless to humans, pets, and other beneficial insects.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #305832; font-size: 21px; font-weight: bold; margin-top: 32px;\"\u003eWhich nematodes for which pest – and how much you need\u003c\/h2\u003e\n\u003cp\u003eThe dosage is calculated based on your planting area. One pack contains 2 million SF nematodes, which is enough for 4 square meters and about 20 plants. For 100 square meters, you would choose 25 packs, for example. The correct species is more important than anything else. SF nematodes against flea beetles are the same species used for fungus gnats and ants: Steinernema feltiae, targeted at larvae in the soil. For vine weevils and grubs, use HB nematodes; for slugs, use the PC variant. The abbreviation before the name determines the target pest. This is a live product, so it is best to apply it immediately upon receipt.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #305832; font-size: 18px; font-weight: bold; margin-top: 32px;\"\u003eWhen are SF nematodes against flea beetles the right choice?\u003c\/h3\u003e\n\u003cp\u003eChoose them if you see shot-hole damage on radishes, arugula, or cabbage and want to use biological methods, especially for vegetables you harvest directly. They are the right choice for soil temperatures between 10 and 28 °C and anywhere you can keep the soil consistently moist for 14 days. And they are the right choice if the infestation returns every year: use them preventively instead of just reacting every spring.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #305832; font-size: 18px; font-weight: bold; margin-top: 32px;\"\u003eWhen nematodes alone are not enough\u003c\/h3\u003e\n\u003cp\u003eThey won't catch the jumping beetles on the leaves. The roundworms work in the soil and on the larvae; the acute feeding damage above ground won't stop immediately—for that, mechanical protection like a pest control net helps as well. At soil temperatures below 10 °C, not enough happens, and the same applies above 28 °C. If the soil dries out in the first 14 days, the application will be in vain, as the nematodes cannot move without moisture. Pesticides applied before or after use will impair their effectiveness. And in cases of severe infestation, one treatment is not enough: a second application is required after seven to 14 days.\u003c\/p\u003e\n\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;\"\u003e🌿 \u003cstrong\u003eConclusion:\u003c\/strong\u003e With GREEN GUARDIA SF nematodes, you target flea beetles where they come from – in the soil, residue-free and safe for plants, humans, and the environment.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp style=\"margin-top: 25px; margin-bottom: 0; font-weight: bold; color: #305832;\"\u003eStart at the bottom so there is peace at the top: Order SF nematodes now!\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Green Guardia - Ihr Schädlingsexperte","offers":[{"title":"2 million for 4m²","offer_id":51294213374291,"sku":"sf_nemato_floh_2_75075","price":45.0,"currency_code":"DKK","in_stock":true},{"title":"3 million for 6m²","offer_id":51294213407059,"sku":"sf_nemato_floh_3_75082","price":53.0,"currency_code":"DKK","in_stock":true},{"title":"4 million for 8m²","offer_id":51294213439827,"sku":"sf_nemato_floh_4_75099","price":61.0,"currency_code":"DKK","in_stock":true},{"title":"5 million for 10m²","offer_id":51294213472595,"sku":"sf_nemato_floh_5_75105","price":68.0,"currency_code":"DKK","in_stock":true},{"title":"6 million for 12m²","offer_id":51294213505363,"sku":"sf_nemato_floh_6_75112","price":76.0,"currency_code":"DKK","in_stock":true},{"title":"10 million for 20m²","offer_id":51294213538131,"sku":"sf_nemato_floh_10_75129","price":99.0,"currency_code":"DKK","in_stock":true},{"title":"15 million for 30m²","offer_id":51294213570899,"sku":"sf_nemato_floh_15_75136","price":122.0,"currency_code":"DKK","in_stock":true},{"title":"20 million for 40m²","offer_id":51294213603667,"sku":"sf_nemato_floh_20_75143","price":137.0,"currency_code":"DKK","in_stock":true},{"title":"25 million for 50m²","offer_id":51294213636435,"sku":"sf_nemato_floh_25_75150","price":175.0,"currency_code":"DKK","in_stock":true},{"title":"50 million for 100m²","offer_id":51294213669203,"sku":"sf_nemato_floh_50_75167","price":251.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/4825\/0195\/files\/sf-nematoden-gegen-erdfloehe-9157438.png?v=1777999886","url":"https:\/\/graenguardia.com\/en\/products\/sf-nematodes-against-flea-beetles","provider":"Green Guardia - Ihr Experte für Schädlinge und Pflanzen","version":"1.0","type":"link"}
