Non-toxic and environmentally friendly, the Plant Stick is used for catching small flies and other insects without using poison in your home. The trap is ideal for catching flower flies, whiteflies, aphids and other insects that thrive in your potted plants. Shake them lightly from time to time so that the insects on the leaves fly upwards and stick to the traps. Regular changing of the trap ensures a pleasent fly-free environment. The sticks can be used all year round and are easy to use.
