Rollertrap Yellow or blue sticky PE ribbon

When to use Rollertrap

Use Rollertrap to trap white fly, leaf-miner, aphid, thrips and fungus gnats in spots with a great pest pressure or areas in the greenhouse where a high pest pressure is expected, for example along gables, ventilation windows and (other) draughty places.

How does Rollertrap work?

Pests are attracted to the yellow or blue colour of the sticky ribbon and get caught in the glue

How to use Rollertrap

Application Rollertrap

Required materials for hanging:
Roll of string, clothes-pegs, paperclips or staples

Before hanging up, make sure the Rollertraps are at least at room temperature. The glue will be softer and the traps will unroll easier.

Instructions for usage:

• Cut off a few pieces of string of approximately 40 cm and keep within reach.
• Tie the loose end of the rope from the roll with a flat knot to the greenhouse pole nearby the concrete path. Do this ± 25 cm above the crop for the small Rollertraps and ± 40 cm for the large Rollertraps.
• Walk with the rope and unroll until the gable.
• On the way back to the concrete path fasten the long end of the rope to every greenhouse pole (or every second greenhouse pole) with the 40 cm-pieces of the string.
• Stab a spar (or other 'expedient') through the Rollertraps roll to hold it.
• Take the beginning of the Rollertrap and wrap it to the first greenhouse pole at the concrete path. Walk slowly with the roll to the side, on which it rolls off.
• Fold the (unglued) upper edge of the trap around the rope and fasten the rope by means of the clothes-peg, paperclip or staples.
• Make, if necessary, the sticky trap heavier with for example a clothes-peg every 2-3 meter, so that the trap will hang straight.
• Go on like this up to the gable (end) (or up to the end of the rope). Cut the trap approximately 40 cm longer than the last greenhouse pole. Wrap the end of the rope to the last greenhouse pole and fasten it to the end of the string.
• Follow the same procedure if you want to hang the Rollertrap along the gable.

Best working conditions Rollertrap

Rollertraps should preferably be installed when the crop is still low. When it comes to ornamental crops, you can use the Rollertraps basically year-round, but with vegetable crops you best install them after the first planting or just before planting. It is advised to use one Rollertrap per two or three greenhouse bays and depending on the pest pressure (to be expected) choose small or large Rollertraps.

Handling

Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.
