How to use: Remove the protective foil from the traps. Hang them above the plants using the ties provided. Alternatively (especially for aphids * and sciarid flies *), place the trap horizontally and remove the covering paper from the top surface. Small flying insects are attracted to the yellow color of the traps and stick to the glue. The traps will remain effective for several months. Replace sooner if more than half the surface is covered with insects or dust. More about: aphids: here * thrips: here *
