How Do Wasps Damage Trees?
WouterSeveral kinds of wasps live in trees and are generally beneficial to plants. They feed on plant sap, and are pollinators of many plants. However, they can also be a pest. They can sting people, and some are allergic to their stings. Wasps are also known to build nests in trees and buildings. If you live in an area with a lot of these insects, you should keep your trees and gardens healthy and pest-free.
Most galls on plants are caused by wasps. These insects produce a chemical that interferes with the growth of the plant cells. They then form a gall, which is a swelling of plant tissue. In some cases, the galls may cause the leaves to fall prematurely. Other galls, like the horned oak gall, can kill trees.
During the spring, adult wasps emerge from their nests and lay eggs in the soft tissue of trees. These eggs are then injected into the plant. The larvae feed on this tissue until they develop into adult wasps. The inner wall of the gall helps to protect the larva from predators and parasites.
Adult wasps feed on the leaves of trees and gardens. They can also be found in sheds and lofts. They are most active during the day. If you are concerned about them, try to keep your garbage cans out of sight and clean them regularly. Also, keep leaves and fruit off the ground.
Wasps can be dangerous because they sting. They can also eat your food, so make sure that you limit your food intake. You can also set traps to keep them away.
