<\/span><\/h3>\nThe chemical control of leaf miners can be done with insecticides that contain the active ingredient spinosad. This active ingredient is approved as a plant protection product in organic farming, but unfortunately, it is dangerous for bees and must therefore not be applied to flowering crops.<\/p>\n
You can either sprinkle or spray insecticides with Spinosad. This remedy is not only suitable for combating leaf miners<\/em>, but can also be used against thrips ( Thysanoptera<\/em> ), Colorado beetles (Leptinotarsa decemlineata), or the cherry vinegar fly (Drosophila suzukii<\/em> ).<\/p>\n<\/span>Fight leaf miners biologically<\/span><\/h3>\nAn effective biological control method for leaf miners<\/em> is the use of beneficial insects such as parasitic wasps<\/em> (Dacnusa sibirica or Diglyphus isaea). The parasitic wasp Dacnusa sibirica<\/em> parasitizes the first larval stages of the leaf miner by laying an egg in the larvae with its ovipositor. The parasitic wasp larvae hatch from this egg and feed on the leaf miner fly, which then dies. The parasitic wasp Diglyphus isea,<\/em> on the other hand, paralyzes the leaf miner larva and then lays an egg next to the leaf miner. After the wasp hatches, this larva feeds on the anesthetized leaf miner larva. After pupation, useful parasitic wasps hatch again and go in search of new leaf miners.<\/p>\n![\"Beneficial](\"https:\/\/gardender.com\/wp-content\/uploads\/2021\/05\/Beneficial-organisms-such-as-parasitic-wasps-can-be-used-to-combat-it.jpg\")
\nIn the case of a low infestation or at the beginning of the infestation with leaf miners, the simplest method of control is to remove the infected leaves, because these also contain the harmful larvae of the leaf miners. Do not put these leaves on the compost, but rather put the infected, plucked leaves in a plastic bag and dispose of them with the household waste.<\/p>\n
Tip: Organic pest-free neem can also be used against leafminer flies and is also made from 100% plant-based and natural active ingredients.<\/div><\/div>\n
<\/span>Fight leaf miners with home remedies<\/span><\/h3>\nAn effective means of deterring the leaf miner flies is the use of nettle manure because the smell of the leaf miner frightens off. In addition, the liquid manure also strengthens your plants. For nettle manure, you only need water and nettles ( Urtica<\/em> ), which you have to ferment in order to obtain effective plant protection and plant strengthening agent. Here you will find out how to make nettle manure and how to use it correctly.<\/p>\n![\"Nettle](\"https:\/\/gardender.com\/wp-content\/uploads\/2021\/05\/Nettle-manure-scares-off-leaf-miners.jpg\")

Combating leafminer flies summary:<\/strong><\/p>\n\n- The active ingredient spinosad is used for chemical control, but it poses a danger to bees, which is why we recommend an alternative control<\/li>\n
- The biological control is most effective via beneficial insects such as parasitic wasps; If the infestation is lower, the affected leaves can simply be removed, which are then disposed of with household waste<\/li>\n
- Nettle manure is ideal as a home remedy, as it also strengthens the affected plant<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
