Bean plants are a popular garden crop for many households. They are easy to grow and provide a bountiful harvest. However, like any garden crop, they are susceptible to pests. One pest that can damage bean plants is the earwig. Earwigs are nocturnal insects that can be difficult to identify. In this article, we will discuss how to identify earwigs on a bean plant and what steps you can take to prevent them from causing damage.
How to Identify Earwigs on a Bean Plant
Earwigs are typically black or brown in color with long, slender bodies. They have two pincers at the end of their abdomen that they use for defense and catching prey. Earwigs are often found in dark, damp places such as under rocks, logs, and in cracks and crevices.
When earwigs infest bean plants, you may notice the following signs:
- Holes in bean leaves
- Chewed or damaged bean pods
- Damage to seedlings or young plants
- Fecal pellets on leaves or near the base of the plant
If you suspect that earwigs are causing damage to your bean plants, you can do a simple test to confirm their presence. Place a rolled-up newspaper or cardboard tube near the base of the plant in the evening. Earwigs will often crawl into the tube for shelter during the day. Check the tube in the morning and if earwigs are present, you have confirmed an infestation.
How to Prevent Earwig Damage on Bean Plants
Prevention is key when it comes to controlling earwig damage on bean plants. Here are some steps you can take:
- Keep your garden area clean and tidy by removing debris such as fallen leaves, weeds, and other plant material.
- Use a sticky trap or barrier around the base of the bean plants to prevent earwigs from crawling up.
- Install yellow light bulbs instead of white or blue lights. Earwigs are attracted to white and blue light.
- Apply diatomaceous earth around the base of the plant. This is a natural substance that will kill earwigs and other pests.
How to Get Rid of Earwigs on Bean Plants
If you have identified an infestation of earwigs on your bean plants, you can take steps to get rid of them. Here are some options:
- Handpicking: Wear gloves and pick earwigs off the plants and drop them into a bucket of soapy water.
- Trapping: Use a rolled-up newspaper or cardboard tube to trap earwigs during the day and dispose of them.
- Insecticides: Use an insecticide specifically designed for earwigs. Be sure to follow the instructions carefully and avoid using near edible plants.
