How To Get Rid Of Flea Beetles Organically

Sharing is caring!

Flea beetles are small, shiny, and dark-coloured beetles that can be a major problem. They are named for their ability to jump like fleas when disturbed.

These pests can damage crops by feeding on leaves, stems, and roots. The hallmark sign of a flea beetle infestation is lots of tiny holes in the leaves; some might not go through all the way.

Flea beetles are most active in warm, dry weather and can rapidly reproduce in favourable conditions.

They can overwinter in garden debris and soil, making it important to clean up garden areas thoroughly in the autumn.

Organic Control Methods

Sticky Traps

These are often used for controlling fungus gnats indoors, but they work equally well outdoors and for flea beetles.

They are sticky cards that the flea beetles get stuck to as they jump between plants.

You need some sticks to feed through the cards; I then put them in between my radish and Chinese cabbage, which were under attack.

Sticky traps are available on Amazon.

As you can see below, they clearly work. But they work a little too well.

There are a lot of insects here that are not flea beetles.

I don’t want to wipe out my insect numbers, so we need a change of tact.

Neem Oil

Neem oil is a natural insecticide that can help control flea beetle numbers while being completely organic.

I bought the below bottle of Amazon. This is a mix with an emulsifier so you can dilute it with water easily.

I got this pressure sprayer at the same time to apply the neem oil.

Simply mix the neem oil and water in the pressure bottle and then spray it onto your affected plants.

The mixture goes a milky white when it is mixed with water.

This seemed reasonably effective, and although I still saw flea beetles after the first application, their numbers where reduced.

Apply in the morning or evening and not in the middle of the day. This is because the heat of the sun can burn the neem oil onto the leaves of your plants, causing damage.

Netting

This is the best way to deal with flea beetles, as long as you set it up before the problem begins.

As you can tell from all the photos above, I didn’t do this.

So I went with a three-pronged approach to remove my flea beetles.

Sticky traps, neem oil, and then netting over the top.

The sticky traps and neem oil should help get rid of the flea beetles already attacking my plants while the netting will stop any more from getting in.

I used this Haxnicks easy tunnel. It has the metal supports already in so setup is easy.

You just pull the tunnel out and push it into the soil.

So there we have it, my insect-proof tunnel with sticky traps inside and neem oil applied regularly.

So the question you will have now is: did it work?

Well, so far so good. The plants are doing well, and I can’t see signs of damage on the younger leaves yet. So, for the time being, at least, it looks like this solution has worked well.

Use of Beneficial Insects

One effective way to control flea beetles organically is by introducing beneficial insects into the garden.

Ladybugs, lacewings, and parasitic wasps are some of the insects that prey on flea beetles. These insects can be purchased and released into the garden.

They will help control the flea beetle population without harming other beneficial insects.

Trap Crops

Another effective way to control flea beetles is by planting trap crops. Trap crops are plants that are particularly attractive to flea beetles.

By planting these crops away from the main garden, flea beetles will be drawn to them instead of the main crops. This can help protect the main crops from damage.

Some examples of trap crops for flea beetles include radish, mustard, and arugula.
