How do I permanently get rid of squash bugs?

To get rid of squash bugs permanently all you need to do is follow two of my pieces of advice. They are using insecticides or using natural ways. 

1. Insecticides

Insecticides can be your best weapon against an infestation. Since squash bug infestation is common and can be hard to deal with, you will eventually use insecticides to get rid of them. But using chemicals can be harmful to your plants.

You will find many products that guarantee getting rid of squash bugs without any environmental safety. You should avoid those products. You should use products that don’t harm your plants and the environment. 

2. Neem oil

Neem oil is one of the best natural ways to eliminate squash bugs. Neem oil has been used by our ancestors and passed down to us. Neem oil will kill squash bugs and also work as a repellent against these bugs.

Neem oil is also helpful for your plants. I would suggest you use neem oil after you use insecticides. Insecticides will quickly get rid of those bugs and later rely on neem oil to nourish your plants. 


Squash bugs are devastating pests that can ruin your harvest and hard work. Instead of calling for professionals, you can deal with squash bugs yourself.

Always remember to inspect your garden properly. Squash bugs will feed on your plants in the early morning and evening. Look for dark spots on the leaves since they indicate squash bugs on your plants.
