What's Eating My Pumpkins?

Pumpkins face the full squash-family lineup all season, and then a second wave of freeloaders once the fruit colors up in fall.

Squash bugs

The signs: Leaves speckle yellow, then brown and crisp; egg clusters like tiny bronze footballs line the leaf undersides.

What it looks like: Flat gray-brown bugs massing near the crown and under dying leaves.

What to do: Squish eggs on sight, board-trap adults overnight, and remove vines promptly after harvest.

Squash vine borer

The signs: A healthy vine wilts section by section; the stem base shows a hole packed with wet orange-tan frass.

What it looks like: White grub inside the hollow stem; parent is a wasp-like orange and black day-flying moth.

What to do: Foil collars or row cover until bloom; slit infested stems, evict the borer, and mound soil over vine nodes so they re-root.

Cucumber beetles

The signs: Ragged seedling leaves, scarred handles and rinds, and wilt disease spread as they feed.

What it looks like: Quarter-inch yellow beetles, striped or spotted.

What to do: Cover young plants; control early before populations build.

Rodents and squirrels

The signs: Gnawed craters in the rind of ripening fruit, often enlarged night after night.

What it looks like: Tooth marks in pairs, damage low on the fruit for mice and voles, anywhere for squirrels.

What to do: Elevate fruit on a board or flat stone, harvest as soon as rinds harden, and repellent-spray prized specimens.

Aphids

The signs: Sticky curled leaves late in the season and virus-mottled new growth.

What it looks like: Dense soft-bodied colonies on leaf undersides.

What to do: Hose off and let beneficials work; soap spray for heavy loads.

When it's not a pest at all

A white talc-like coating spreading across leaves in late summer is powdery mildew — nearly universal on pumpkins and rarely fatal by that point in the season. Fruit that rots where it touches soil is moisture, not teeth.
