Squash bugs are a common pest in gardens across the country, known for their destructive habits and resistance to many common pesticides. The question that plagues many gardeners is: does Sevin kill squash bugs? The answer is a resounding yes. Sevin, a widely-used insecticide, is highly effective in controlling squash bug populations. However, it’s essential to understand how it works, its application, and potential risks.
Yes, Sevin does kill squash bugs. It is a widely-used insecticide that is highly effective in controlling squash bug populations. However, while it kills the bugs, it does not affect their eggs. It’s also important to note that Sevin carries some risks, including toxicity to pollinators, potential health risks, environmental concerns, and impact on beneficial insects.
What is Sevin?
Sevin is an insecticide originally derived from a carbamate compound. Its primary active ingredient is carbaryl, a powerful insecticide effective against a wide variety of insects. Carbaryl works by disrupting the normal functioning of an insect’s nervous system, leading to its eventual death.
In recent years, the Sevin trademark was acquired by GardenTech, which has replaced carbaryl in most Sevin formulations with zeta-cypermethrin, a newer pyrethroid insecticide.
How Sevin Works Against Squash Bugs
Sevin is effective against squash bugs, killing them upon contact. The active ingredients zeta-cypermethrin and bifenthrin in Sevin help eliminate squash bugs, making it a reliable product against these pests. However, while Sevin dust kills the squash bugs, it does not affect their eggs.
Applying Sevin for Effective Squash Bug Control
To effectively kill squash bugs using Sevin, follow these steps:
- Choose the right Sevin product.
- Apply Sevin at the right time.

The Risks of Using Sevin
While Sevin is effective, it also carries risks. These include toxicity to pollinators, ineffectiveness against eggs, potential health risks, environmental concerns, and impact on beneficial insects.
Alternatives to Sevin for Squash Bug Control

Sevin vs. Other Pesticides
Sevin is highly effective against squash bugs. However, other insecticides, such as those containing esfenvalerate, permethrin, or carbaryl, can also control squash bugs. The effectiveness of these insecticides varies with different life stages of the bugs.
Preventative Measures Against Squash Bugs
Preventative measures include practicing good sanitation, handpicking or vacuuming bugs, using protective covers, trellising, planting resistant varieties, companion planting, attracting beneficial insects, using row covers, handpicking eggs and bugs, applying diatomaceous earth, and using neem oil.
