Organic Control of Squash Bugs on Pumpkins and Squash

Identifying the Pest

The powder‑gray bugs that turn brown are squash bugs (stink bugs). Eggs are laid on leaf undersides in late spring; nymphs hatch and mature into the adults you see.

Organic Management

• Hand‑picking: Drop bugs into soapy water daily.
• Homemade sprays: Garlic spray or 1 tbsp lemon ammonia + 1 tbsp dish soap per gallon water, applied every other day for two weeks.
• Botanical insecticides: Rotenone or pyrethrum every three days for two weeks; non‑toxic to humans and safe up to harvest.

Prevention for Next Season

Cover young plants with floating row covers (Reemay) until flowering to exclude egg‑laying adults.
