Best for

Luring cucumber beetles, flea beetles, aphids, and squash bugs away from main crops

Placement

Plant the trap crop 2–3 weeks before the main crop so it is attractive when pests arrive.

Boards to Buy

Boards to Buy	Quantity	What You Use Them For
Nasturtium seed	1 packet	Aphid and squash bug trap
Radish seed	1 packet	Flea beetle trap
Blue hubbard squash seed	1 packet	Squash bug and vine borer trap
Yellow mustard seed	1 packet	Harlequin bug trap

1Pick one pest to target. Nasturtium isn't a flea-beetle fix, radish isn't for squash bugs, and sowing all four packets 'just in case' wastes seed.
2Choose one or two trap crops based on your worst pests.
3Sow the trap crop in a band around or just outside the main bed.
4Plant it 2–3 weeks earlier than the main crop.
5Keep trap crops healthy and watered — stressed plants don't attract pests.
6Check trap crops twice weekly and hand-pick, smash, or vacuum pests there.
7Remove and destroy trap crops if pest pressure gets overwhelming. Don't compost a bug hotel — bag or burn it.
8Rotate trap crop locations each season.

·Planting the main crop first and the trap crop last — the trap has to be ready before the pests arrive
·Not checking the trap crop — it becomes a pest nursery
·Planting trap crops too far from the main crop
·Using trap crops alone — combine with row cover or hand picking

Scout trap crops twice a week. Smash, vacuum, or pull heavily infested plants before pests spread. Destroy trap crops at the end of the season.
