10 Plants That Deter Squash Bugs - Natural Remedies to Protect Your Crop

What are squash bugs?

Squash bugs (Anasa tristis) are common pests that affect squash, pumpkin, zucchini, and other related plants. Adult squash bugs lay their eggs on the underside of plant leaves and these eggs hatch into nymphs which can cause a lot of damage to crops.

Impact of Squash Bugs on crop yield

Squash bugs feed on the sap from plant leaves and stems which can reduce the growth of these plants. They can also transmit diseases like bacterial wilt which can quickly kill an entire squash plant or even spread to other crops if not addressed.

Why use natural remedies?

Natural remedies are becoming increasingly popular as more people prioritize sustainable gardening practices and minimizing environmental impact. Additionally, harsh synthetic pesticides can be harmful to beneficial insects and can leave residues on your vegetables.

To help prevent squash bug infestations, here are some tips and tricks you can use:

Remove debris from the garden

Squash bugs are attracted to debris like old plant material, dead leaves, and weeds. Be sure to clean up any garden debris to limit the spots where they can hide and breed.

Organic pest control methods

Organic pest control involves using natural solutions like insecticidal soap or neem oil to coat squash bugs and eventually kill them. These substances usually don’t harm humans or pets and often have less impact on the environment.

Use companion planting

Companion planting refers to planting certain crops or herbs around your squash plants that help deter pests like squash bugs. Some plant examples with natural insect-repelling properties include marigolds, tansy, and garlic.

Beneficial insects in the garden

Beetles, certain types of wasps, and ladybugs are among the beneficial insects that can eat eggs and nymphs of squash bugs, thus preventing a future infestation. You can attract these helpful insects by growing plants like parsley, fennel, or carrots, which they enjoy.

Here are the top ten plants that you can grow in your garden to prevent squash bug infestations:

1. Marigold

2. Nasturtium

3. Radish

4. Tansy

5. Mint

6. Catnip

7. Garlic

8. Chives

9. Rosemary

10. Sage

If you're looking to create a natural insect repellent to protect your squash plants, here are some effective options:

Neem oil spray

Neem oil is extracted from the seeds of the neem tree and can coat plants as a natural insecticide. It's safe for people and pets but can irritate your eyes and skin, so be sure to wear protective gloves and other equipment as needed.

Soap and water spray

A simple mixture of dish soap and water sprayed onto your squash plants can coat insects like squash bugs and cause them to suffocate. This solution works best on adult bugs and requires repeated applications to truly eliminate an infestation.

Peppermint oil spray

Peppermint oil's strong but pleasant scent can help repel squash bugs along with other garden pests. Simply mix one teaspoon of peppermint oil with a quart of water and add it to a spray bottle. Be sure to re-apply every few days.

Certain herbs like rosemary, dill or mint can be grown around squash plants that may repel squash bugs, so growing these companion plants can help deter or reduce their populations.

Utilizing natural remedies can be a simple and effective way to manage squash bugs in your garden. By incorporating these plants and methods into your garden management plan, you can protect your crop sustainably and without the use of harsh chemicals.
