What to spray on green beans for bugs?


The simplest method to get rid of those beetles or aphids on your green beans is to spray water on them.


If you have sprayed water on these beetles but nothing changed, try spraying pesticides on them. However, remember to choose suitable pesticides based on our guides below to protect your gardens and your health.

Choose insect repellent registered with the  Environmental Protection Agency (EPA)

The first rule is to choose bug repellent registered with the Environmental Protection Agency. Repellent manufacturers are required to conduct studies and statistics regarding the product’s efficiency and impact on buyers’ health and environment on a daily basis.

If the repellent is unregistered, it means the product fails to meet the standards of the EPA, making it unsuitable for your vegetables and harmful to your health.

Biological insecticides

We highly recommend you use this kind of insecticide as it stops bugs from eating the crop’s leaves but do not directly kill them. Instead, bugs will die from starvation later on. 

Unlike other insecticides that are harmful to green beans, antifeedants of biological insecticides are harmless, making them an ideal type of insecticide for agriculture practices. 

Moreover, they are totally environment-friendly and highly effective even when used only a small amount. So this type of insecticide does wonders in getting rid of annoying bugs and protecting both your health and your green beans.

Don’t use insecticides which contain metal 

You should not use insecticides that contain metal like asen. Asen was once used in insecticides in agriculture. However, due to its toxicity, it’s now rarely applied. 

Insecticides containing metal exert bad impacts on both the environment and your health, causing pollution and health diseases. 

Tips to get rid of annoying bugs for your beans

Use physical barriers

Cover your beans with a lightweight, floating row cover to make them inaccessible to bugs. It’s definitely the easiest way to protect your gardens from aphids or beetles.

Attract beneficial bugs

Attract more beneficial bugs such as ladybugs, lacewings, parasitic wasps, etc to your gardens so that they will help you control the harmful bugs by eating them.

You should grow a lot of flowers such as cosmos, dill, yarrow, etc in your garden or next to your green beans to tempt more beneficial insects.

Don’t utilize your beans so much

When you provide your beans with too much Nitro, you will attract the aphids or beetles and your gardens are more likely to be harmed.

Use insect killers for your garden

You should consider buying a suitable insecticides to protect your garden. Before making a purchase, consult experienced gardeners or look for information online to ensure you get the right insect killers. 

Identify harmful bugs 

Learning to identify which type of harmful bugs they are and their specific damages is highly advisable for any gardeners. This knowledge will be of great help in performing home control methods or seeking help from garden services if things get worse.

Remove entire crops after harvest 

After the last green beans have been harvested, immediately remove the entire crops in that space. Those stubborn bugs that were driving you nuts this year might lay their eggs and emerge stronger as ever next year to attack your new precious plants in the same space.
