Pest identification
What's eating my delicata squash?
Squash vine borer
Signs: Wilting main stem; sawdust-like frass pushed out near the soil line; plant death if untreated
Control: Time planting to avoid peak moth flight (late June–July in most US zones); use floating row covers; bury damaged vines to encourage adventitious rooting
Squash bug
Signs: Yellow spotting that browns and dries; egg masses on leaf undersides; wilting despite adequate water
Control: Remove egg masses manually; neem oil spray on nymphs; keep garden tidy to reduce overwintering sites
Cucumber beetle
Signs: Feeding scars on the thin delicata rind; bacterial wilt causing rapid plant collapse
Control: Row covers until pollination; kaolin clay applications; pyrethrin sprays as a last resort
Deer and rabbits
Signs: Cleanly browsed seedlings and young leaves; whole transplants removed overnight
Control: Hardware cloth cloches over transplants; deer-repellent sprays; 8-ft fencing for persistent deer pressure
