Options on how to get rid of leaf miners

If you’ve got leaf miners in your garden, here are the things you can do.

1. Natural way on how to get rid of leaf miners

The best way to get rid of leaf miners is to use natural methods first, such as the following.

  • Watering

Watering your plants well can help prevent leaf miner infestations. If you’re watering them regularly, the leaf miners won’t be able to survive and reproduce as easily.

  • Seaweed

Seaweed can help keep your plant healthy and resistant to pests, including leaf miners. Add a little seaindweed fertilizer every time you water your plants, and they’ll be fine!

  • Neem Oil

Neem oil is another great natural remedy for getting rid of leaf miners. You can buy neem oil online or at most nurseries/garden centers. You can have either powder or liquid form. Spray carefully over any infected leaves and watch those pesky pests disappear!

2. Use of chemicals on how to get rid of leaf miners

There are a few chemicals that can get rid of leaf miners, including:

  • Bacillus thuringiensis

It is a bacteria that kills leaf miners when eaten by larvae. It’s been used for years in organic farming and is approved for use on food crops by the EPA. It won’t affect humans and other animals but can be harmful if ingested by pets or wildlife.

  • Spinosad

It is a chemical made from a naturally occurring soil bacterium. It is derived from Spinosus plants and kills leaf miners as well as many other pests.

It’s considered safe for humans, pets, and wildlife but should not be used on bee-attractive plants because it may kill bees who come into contact with it.

  • Dipel DF

It is a microbial insecticide that can be used to kill leaf miners. Applying the product in the evening when the temperature is above 70 degrees Fahrenheit is recommended. 

The product should be applied once a week until the infestation is under control or until the leaves begin to yellow and drop off.

  • Insecticidal soap

It is a natural insecticide that you can use to kill leaf miners. It’s a mixture of water, potassium salts, and fatty acids that creates a chemical reaction with the leaf miner’s exoskeleton and kills it on contact.

3. Biological control on how to get rid of leaf miners

There are a number of natural enemies that can help get rid of leaf miners. These include the following.

  • Ladybugs

Ladybugs are the best exterminators. They love leaf miners and are really good at killing them.

If you’re seeing lots of leaf miners on your plants, you might want to consider getting some ladybugs to eat them up. 

Ladybugs are voracious eaters, and they’ll take care of your leaf miner problem in no time flat. There’s just one thing you have to be careful about.

Ladybugs can’t fly when they’re full! So if you get a lot of ladybug eggs, make sure you put them in an area where they won’t be disturbed until they hatch into adults. Otherwise, all that food will go straight to waste.

  • Lacewings

Lacewings are very small but can wreak havoc on a leaf miner population.

The lacewing lays her eggs on leaves where she thinks leaf miners are most likely to be found.  

Then, when the eggs hatch, the larvae start eating the leaf miner eggs and larvae. Since they’re so small, they can fit into the spaces between leaves where most other predators cannot reach them.

There are many different types of lacewings, each with its own special way of killing leaf miners. Some species lay their eggs in groups or clusters instead of alone as other kinds do. This gives them better odds of finding an egg or larva to eat!

  • Parasitic wasps

Parasitic wasps are the most effective way to get rid of leaf miners, but they can be tricky to find.

They also lay their eggs inside the larvae of other insects like leaf miners, and when those larvae hatch, they kill them from the inside out. And then they move on to find more hosts!

Parasitic wasps are pretty hardy creatures themselves. They have a long lifespan, up to seven years, and they don’t need much food. They’ll happily live off pollen if there isn’t anything else available!
