How To Use:
If you use a commercial trap, peel off the protective coating and install the trap near the plants you wish to protect. Traps can be hung from branches or attached to stakes.
The traps will collect pests continuously. This reduces the pest population and also is useful for monitoring. To make a homemade trap, paint a board or piece of cardboard with yellow paint and cover it with Tanglefoot Insect Trap Coating or other sticky material. The yellow color attracts the insects.

Non-toxic. Easy to install. Helps to monitor pest populations.
Concerns:
Several traps may be required. Traps are quite visible. Traps alone may not provide sufficient control. Should be used in conjunction with other controls if pest problem is serious.
