There are several natural methods of controlling the Colorado potato beetle. It’s important to remain vigilant and proactive when it comes to beetle control so you can prevent unnecessary crop damage. If your potatoes are growing here and there, you might want to spice them up a little. Natural pests can be a natural potato plant killer.

If you’re more concerned with organic farming and would rather not put chemicals in the soil, this article will help you spot early signs of pests on potato plants and suggest natural ways to get rid of them.

Natural Pest Control For Potato Plants

Colorado Potato Beetles

Colorado potato beetles are known for their yellow and black striped body. They feed on potato leaves, causing serious damage. The adults lay their eggs on the underside of leaves and the larvae burrow into stems to pupate; this can cause plants to become weak and die.

Colorado Potato Beetles overwinter in the soil or as adults under leaf litter. There is one generation per year.


Aphids are small, pear-shaped, soft-bodied insects that are usually green but can be brown, yellow or red. Their legs and antennae are usually black. The nervous system of aphids is very simple – as a result they do not feel pain when attacked by predators like ladybirds or birds. This means that they will continue to feed on the plant even when they are being eaten themselves!



  • Cutworms are a problem for potato plants.
  • They are the larvae of night-flying moths and can be handpicked from plants or soil.


Earwigs are a common pest that eat flowers, leaves and other plant parts. They can be found under rocks or logs during the day and are nocturnal. The best way to control earwigs is to use a rotenone-based insecticide, which can be found in most nurseries.

Flea beetles

Flea beetles are small beetles that can jump like fleas when they are disturbed or threatened. They feed on the leaves of the plants, creating holes in the leaves and eventually causing them to fall off. Flea beetles are a common pest of potatoes and other vegetables, including tomatoes and eggplants.


Grubs are the larvae of beetles. They live underground, eating the roots of potato plants as they grow. The best way to control grubs is by using beneficial nematodes. There are many types of beneficial nematodes available at garden centers, but only some will work on grub infestations. Follow directions carefully when applying beneficial nematodes in order to get the most effective results possible!


Leafhoppers are small insects that feed on plants. They are often found feeding on the underside of leaves, which means they can be hard to spot unless you look closely. The most obvious sign of leafhopper infestation is spotting the insects themselves on your potato plant or in its vicinity. Leafhoppers also leave behind a white residue called honeydew, which looks like soot and can coat stems and leaves with an unsightly black film.

While not harmful to potatoes themselves, leafhoppers do damage them by sucking sap out of tender shoots and leaves during their feeding process. This causes young plants to wilt and older plants to lose vigor; it’s not uncommon for them to die from this loss of energy if left untreated for too long! If you notice your potato plants wilting or have recently noticed a sudden increase in insect activity (like ants), there’s likely an infestation nearby—but don’t worry: there are plenty ways you can get rid of these pests before things get worse!

Potatoes flea beetles

One of the best methods of controlling flea beetles is to install a floating row cover. These covers are placed over your potato plants and remain on top of them until harvest, at which point you remove them. A floating row cover will protect your potatoes from pests like fleas and other insects that can cause damage to the leaves, stems and tubers.

Another effective method of natural pest control for flea beetles is by using beneficial insects such as ladybugs or praying mantises (also known as “praying mantis egg cases”). These insects have a voracious appetite for flea beetles when they hatch out in early springtime, before their natural predators emerge. They also work well because they are generally easier to find than beneficial nematodes (tiny worms) which can be difficult to locate if planted incorrectly or under unfavorable conditions.

Since many chemicals used in conventional insecticides pose health risks not only for humans but also pets living around an infested garden area – it’s important that you take steps toward preventing further damage by incorporating methods like these into your home garden routine!

Potato leafhopper

The potato leafhopper is most damaging to potatoes in the early growth stages. The nymphs are pale green and have no wings. Leafhoppers are about 1/8 inch long and are yellow-green with a white stripe on the sides. They feed on leaves by sucking plant juices from under the surface, which can cause them to develop chlorotic (yellow) or necrotic (dead) areas on the leaf. Plants may also wilt if too many leafhoppers damage their roots, tubers will crack after harvest if plants were heavily infested earlier in their growth cycle, and plants may die back from damage done at tuber initiation or during flowering before you even see any symptoms above ground

Here are some tips to control pests in your garden.

  • Before choosing a natural pest-control method, you should first identify the pests in your garden. Identify their type and what they’re eating.
  • If your potato plants are being eaten by beetles, then you can control them with apple cider vinegar or diatomaceous earth.
  • You can use garlic oil to kill aphids on your potatoes.
  • You can spray neem oil on tomato plants that have been attacked by slugs or snails to keep them from eating any more leaves than necessary. This may be harmful for bees though so be careful when using this product!
