How do Substral sticky traps differ from ordinary yellow sticky traps?

The traps are coated with glue on both sides, increasing the trapping area. The set includes 5 reusable metal holders, so when a trap is full, you only need to replace the card. The glue is odorless, does not dry out or drip, and does not get on your hands during installation.

How should I use sticky traps for fungus gnats in pots?

Slide a trap onto the holder, remove the protective film and push the holder into the soil near the plant - 1 trap per pot, or 2 joined together for large plants. Gently shake the plant to make the insects take flight. The trap catches adult fungus gnats, so it works best when used continuously until they stop appearing.

Can the traps be used all year round and in a greenhouse?

Yes - the traps contain no insecticides, so they are suitable for continuous use, including in winter around potted plants and in a greenhouse. For tall plants and whiteflies, you can hang a trap directly on the plant, using one for every meter of height.
