Grow1 | Sticky Card Traps Blue 3" x 5" (10 Pack)
Grow1
$4.99
A 10-pack of 3" x 5" blue sticky cards for spotting and catching flying pests before a population builds. Blue is the color for thrips, which these cards catch best, and they also trap aphids and whiteflies.
The cards are double-sided and waterproof, so they hold up in a humid tent or greenhouse and outdoors. Cut them down for small pots or tight spaces. They work as a monitoring tool in an IPM program: count what you catch and you know when and where to treat.
Tip: hang cards just above the canopy and move them up as plants grow.
