This glue with a very high adhesive power is not very sensitive to the action of rain or temperature variations. It does not harden in the cold and does not flow in the heat. It does not contain elements likely to damage the bark, if it is applied directly to the trunk. Tree glue can be used to create a real barrier on which the various insects will get stuck and die. How to use tree glue? Using a spatula or a knife, coat the circumference of the trunk with glue, about 1 m from the ground, in order to create a complete barrier a few centimeters wide. For very young trees whose bark may be fragile, place the glue on a flat collar made of a ribbon or strip of fabric or baking paper fixed with a few dots of glue for example. Spring - summer: to trap ants and other insects. Autumn: to destroy insects that settle in trees to lay eggs and overwinter.
