What's Eating My Watermelon?

Watermelon shares the squash family's enemies early, then faces a uniquely painful endgame: something cracking open the fruit you waited ninety days for.

Cucumber beetles

The signs: Chewed seedling leaves, scarred stems, and the bacterial wilt they carry — vines that wilt and die section by section.

What it looks like: Small yellow striped or spotted beetles from emergence onward.

What to do: Row cover until flowering, sticky traps after, and pull wilt-stricken vines promptly.

Squash bugs

The signs: Speckled yellowing leaves collapsing to brown; bronze egg clusters underneath.

What it looks like: Gray-brown shield bugs at the crown and under leaves.

What to do: Crush eggs weekly, board-trap adults, clear fall debris.

Aphids

The signs: Curled sticky leaves and stunted runners.

What it looks like: Colonies under leaves at growing tips.

What to do: Water blasts and beneficials; soap for outbreaks.

Coyotes, raccoons, and crows

The signs: Ripe melons cracked open or holed in the field, centers scooped, seeds scattered.

What it looks like: Crows drill neat holes; raccoons and coyotes break and hollow the fruit — all with unerring ripeness timing.

What to do: Harvest at ripeness without delay, fence or electric-strand the patch, and cage prized melons under crates as they finish.

Spider mites

The signs: Stippled bronzing leaves with fine webbing in drought heat.

What it looks like: Tap-test specks on paper.

What to do: Hose undersides regularly; keep vines watered and unstressed.

When it's not a pest at all

Sunken dark leathery patches on the fruit's underside are belly rot from soil contact — set fruit on boards. Hollow or mealy centers trace to pollination and watering swings, not tunneling.
