A spinosad spray can also be effective at killing off adult moths and their eggs.
Do beneficial nematodes kill squash bugs?
Beneficial nematodes seek out and kill all stages of harmful soil-dwelling insects. They can be used to control a broad range of soil-inhabiting insects and above-ground insects in their soil-inhabiting stage of life.
Are nematodes beneficial?
Beneficial nematodes as pest control will attack soil borne insect pests with no harmful effects on earthworms, plants, animals, or humans, making it an environmentally friendly solution. They are morphologically, ecologically, and genetically more diverse than any other animal group with the exception of arthropods.
Is there a downside to nematodes?
Beneficial nematodes are natural and effective for getting rid of target pests, but they have disadvantages, too, including: They only work for pests in your soil. They will not harm pests that live and feed on plant leaves (unless those pests have a soil-dwelling stage in their life cycle).
How do I get rid of nematodes in my soil?
To kill nematodes in soil, heat small quantities of moist soil to 140°F in the oven or by solarization. Heating soil in the oven over a time period needed to bake a medium-sized potato placed in the center of the soil is sufficient to kill nematodes; however, this is only practical for small quantities of soil.

How do you control nematodes?
The most reliable practices are preventive, including sanitation and choice of plant varieties. You can reduce existing infestations through fallowing, crop rotation, and soil solarization. However, these methods reduce nematodes primarily in the top foot or so of the soil, so they are effective only for about a year.

What plants are resistant to nematodes?
In the home landscape, some bedding plants are resistant to root-knot nematodes including zinnia, salvia and marigold. Some damage may occur to snapdragons and pansies, especially when plants are stressed. Begonias, coleus and impatiens are most likely to be damaged in areas where root-knot nematodes are a problem.
