Designed for use in greenhouses, livestock farms and orchards, this double sided sticky roll trap is ideal for attracting and trapping small flying insects including whiteflies, aphids, sciarids and phorids. The yellow colour it emits is irresistible to these flying insects and acts as a powerful attractant. Made with a special hi-tech glue, this trap is also water resistant and guaranteed to remain sticky for up to a 1 year. This trap is 100 meters long and should be hung horizontally above the crop just after crop emergence. Fit around the sides of the greenhouse or between rows.
