As described above, you need a few things to attract the cucumber beetles and something sticky to catch them. In our version of Susan's trap we made our own clove-infused oil, in which we soaked cotton balls. We then placed the cotton balls in yellow plastic cups which we painted with Tanglefoot insect barrier (a very sticky substance designed to trap bugs getting into your fruit trees). You'll also need some twist ties to attach the trap to a stake or to your support structure if your cucumbers are set up to grow vertically. Scroll down for more specific instructions.
