Types of Potato Bugs and What They Eat

Potato bugs are a common pest of plants in the nightshade family, including potatoes, eggplants, tomatoes, and peppers. Below you see more on each type of bug.

1. Colorado Potato Beetle

This is a bug with a yellowish color and brown stripes which extend all the way to its back. These types of bugs seem to appear out of nowhere in no time at all. Feeding mainly on potatoes, these types of bugs are the most destructive type as they are able to go through a whole potato crop in a very short time.

2. Potato Leafhopper

These small, wedge-shaped bugs are very active yet frequently unseen because of their size and tendency to feed on the underside of potato leaves. These kinds of bugs use piercing and sucking mouthparts to take out the sap from potato leaves.

Infestation from these types of insects can be spotted by a triangle-shaped brown mark at the very tip of the leaves, which makes them roll upward as though the leaves have been seared at the tip. When you notice this, you can inspect the underside of the leaves to see if there are these bugs.

3. Flea Beetles

These kinds of bugs are so named as the adults tend to hop like a flea from plant to plant. They don't just cause damage to potatoes but to other plants as well when they leave their larva behind. The larvae of the flea beetles destroy crops as they burrow through the potatoes or other tubers, which then leaves the crops vulnerable to fungus, rot, and bacteria.

4. Jerusalem Cricket

This particular type of bug may cause most people to be startled as it is quite big. Measuring up to 50 mm long, it is yellow and brown with a big head and beady eyes. Jerusalem crickets are nocturnal and primarily feed on insects, roots, and tubers, which include potatoes, which makes your garden the best environment for this type of bug.

You'd know that there is an infestation of Jerusalem Crickets in your garden when they start appearing inside your home, which could be very concerning.

5. Blister Beetle

Blister beetles are can be found near deserts or range lands. Measuring from ¾ of an inch to about 1 ½ inches in length, these types of bugs feed on the leaves of potato plants, leaving them looking a bit tattered. They don't generally do much damage to potatoes themselves, only to the leaves.

How to Avoid the Emergence of Pesky Potato Bugs

There are different ways of getting rid of potato bugs in your garden to be able to successfully grow your plants and harvest your crops when the right time comes. There are different ways to get rid of different types of bugs, depending on the level of infestation. The most important thing to remember is to be observant to be able to catch these bugs early on.

Avoidance is better than cure. Being able to inhibit the invasion of potato bugs in your crops should be the first thing to think about as this would help you avoid a lot of problems.

  • A great way to do this is to plant "trap crops" a good distance away from your vegetable crops. These types of plants are those that the bugs would tend to prefer more than your crops. They then feed on the trap plants, keeping your crops safe!
  • In the case of potato beetles, you may be able to avoid their appearance by digging a trench around your potato crops and covering it with plastic. Then lightly sprinkle some soil on the plastic as, for some reason, these beetles cannot get across plastic when it has soil on it.
  • Prevent potato leafhoppers from getting to your plants by using floating row covers which will serve as a barrier. It's also a good idea to get rid of the garbage and other such waste after harvesting to keep these bugs away.
  • You also have the option to plant "companion plants," which may drive some of the bugs (especially flea beetles) away. Examples of these plants are coriander, marigold, or horseradish. Planting these kinds of plants may prevent your whole garden from being damaged.
  • To prevent the infestation of Jerusalem crickets, all you have to do is remove logs, rocks, and other objects outside which may serve as a hiding place for these bugs. Also, if you have sprinklers in your garden, it would be a good idea to turn them on during the day.
