Ness Ziona Plans Targeted Pine Tree Treatment for Early December

Ness Ziona Municipality plans to treat pine trees throughout the city at the beginning of December to reduce the risk from pine processionary caterpillars. The planned work involves targeted treatment applied directly into tree trunks. The municipality says that, because the treatment is delivered inside the trunk, it does not expect side effects or a risk in the surrounding area. It has asked residents who identify the caterpillars to avoid contact and notify municipal hotline 106. The city's warning describes possible harm to children and adults, including inflammation affecting the eyes and respiratory system, bronchitis and asthma. KKL-JNF's forest-health information explains that the caterpillars carry microscopic defensive hairs containing toxic substances. Shed hairs can disperse and remain on the ground, creating irritation risks, particularly for children and sensitive people. Its account also identifies the eyes and airways as vulnerable to exposure. The caterpillars develop through five stages, each lasting roughly two weeks to a month, according to KKL-JNF. From the third stage, they build fixed silk nests that shelter them during the day, then feed on pine needles at night. The nests protect them from predators, rain, wind and cold.
