|NOTE||THE PRICE INDICATED IS PER UNIT.|
The processionary caterpillars produce two types of damage: the first, which affects the plants, causes the loss of needles, since the caterpillars feed from the end of winter to the middle of the spring of pine and cedar needles.
On the other hand, the caterpillars are strongly allergenic, being able to produce severe allergic outbreaks in people and animals, both in forest areas and in parks and gardens.
The PROCESSIONARYTRAPNEX® L trap is designed to capture caterpillars of pine processionary Thaumetopoea pityocampa, when they descend through the trunk of the trees where they have made nests. The aggregative and social behaviour of this species is used to capture the whole group of larvae when they go to the ground to bury and pupate.
The trap consists of a black PET film of 150 x 25 cm and 0.3 mm in thickness, and of a polyurethane foam bar of rectangular section of 5 x 7 cm x 150 cm in length, crossed in its middle part by a corrugated tube that connects with a polyethylene bag with its lower half opaque.
The black sheet is covered on its inner side by a film of contact glue (without solvents) to facilitate the assembly and to dissuade the processionary caterpillars from climbing up the sheet, forcing them to descend through the tube towards the bag, where they remain retained.
ACTIVATION OF THE TRAP
Identify trees with active nests of processionary caterpillars, making sure they have not yet descended. Read carefully the instructions included in the trap box. Remove the protective paper from the sheet. Stick the foam bar on the bottom of the sheet, taking care that the bag is approximately in the center. Present the set around the tree and mark the excess foam in the overlapped part. Cut only the excess foam, DO NOT CUT THE SHEET.
Install the trap around the trunk, so that the foam completely surrounds the perimeter of the tree, without holes, sticking the sheet with the overlapped part. The bag should be more or less centered. Secure the overlapping part with staples both on the top and the bottom. Check the foam fit to the trunk looking from below. If there were significant holes, fill with the remaining foam.
The trap is suitable for pine trees with a trunk perimeter less than 130 cm. For trees with a perimeter greater than 110 cm use two or more sheets and foam bars. The sheets must overlap at least 15 cm, ensuring overlapping with staples.
Safety advice: Handle the trap with protective gloves. In case of unprotected handling, wash hands after use.
If the caterpillars are inside the trap, handle with extreme care: USE RESPIRATORY PROTECTION MASK. AVOID CONTACT WITH SKIN.
