How to Beat Squash Bugs with Plants
Squash bugs are nasty pests that can ruin your squash, pumpkin, and other cucurbit crops. They suck the sap from your plants, inject them with toxic venom, and even spread diseases. But don’t despair! Companion planting is a natural and effective way to control these destructive insects.
What is Companion Planting?
Companion planting is the practice of growing different plant species together for mutual benefits. In the case of squash bugs, certain plants can help to deter or repel these pests, while others attract their natural predators.
Plants That Deter Squash Bugs
- Bee balm
- Calendula
- Catnip
- Chives
- Dill
- Garlic
- Marigolds
- Marjoram
- Mint
- Nasturtium
- Onion
- Oregano
- Tansy
Plant these herbs and flowers around your squash plants to create a protective barrier against squash bugs. Their strong scents and volatile compounds act as natural repellents, keeping these pests away.
Plants That Attract Squash Bug Predators
- Carrots
- Dill
- Parsley
- Sunflowers
- Radishes
These plants attract predatory insects such as the feather-legged fly, bigeyed bug, and damsel bugs. These beneficial insects feed on squash bug eggs and larvae, helping to control their populations.
Squash Bug Predators
- Feather-legged fly (Trichopoda pennipes): The larvae of this fly burrow into adult squash bugs, eventually killing them.
- Bigeyed bug (Geocoris punctipes): These bugs feed on squash bug eggs and young larvae.
- Damsel bugs (Nabis sp.): Damsel bugs suck the body fluids from their prey, including squash bugs.
Using a Squash Bug Trap
Another effective method of controlling squash bugs is to use a trap plant. This is a type of squash that is highly attractive to squash bugs. By planting a trap plant away from your main crop, you can lure the pests away and then eliminate them.
Blue Hubbard Squash as a Trap Plant
- Blue Hubbard squash is an excellent choice for a trap plant. It is highly attractive to squash bugs, squash vine borers, and other pests.
- Plant blue Hubbard squash two weeks before sowing your main crop.
- Plant the trap crop away from your main crop, either in the corners of your garden or at a distance of 3 to 8 feet.
- Regularly check the trap plant for pests and eliminate them as needed.
Conclusion
By using companion planting and trap plants, you can effectively control squash bugs and protect your cucurbit crops. These natural methods are safe, sustainable, and easy to implement. So next time you see squash bugs invading your garden, reach for your plants instead of harsh chemicals.
