Sapsuckers – Definition & Detailed Explanation – Tree Diseases and Pests Glossary

I. What are Sapsuckers?

Sapsuckers are a type of bird belonging to the woodpecker family. They are known for their unique feeding habits, which involve drilling small holes in trees to extract sap. Unlike other woodpeckers that primarily feed on insects found beneath the bark of trees, sapsuckers rely on the sugary sap that flows beneath the bark of certain tree species. Sapsuckers are found in various regions across North and South America, with different species adapted to different habitats.

II. How do Sapsuckers Damage Trees?

Sapsuckers can cause significant damage to trees through their feeding habits. By drilling small holes in the bark of trees, sapsuckers create wounds that can weaken the tree and make it more susceptible to disease and pests. The repeated drilling of holes can also disrupt the flow of sap within the tree, leading to nutrient deficiencies and reduced growth. In severe cases, sapsucker damage can result in the death of the tree.

III. What are the Signs of Sapsucker Damage?

There are several signs that indicate a tree has been affected by sapsuckers. One of the most obvious signs is the presence of small, evenly spaced holes in the bark of the tree. These holes are typically arranged in rows or columns and may be surrounded by a ring of discolored or dead tissue. In addition to the holes themselves, sapsucker damage can also cause the tree to exhibit symptoms such as wilting leaves, stunted growth, and an overall decline in health.

IV. How to Prevent Sapsucker Damage?

There are several measures that can be taken to prevent sapsucker damage to trees. One effective method is to discourage sapsuckers from feeding on trees by providing alternative food sources, such as suet or fruit, in bird feeders. Another approach is to wrap vulnerable trees with hardware cloth or burlap to prevent sapsuckers from accessing the bark. Pruning dead or damaged branches can also help reduce the attractiveness of trees to sapsuckers.

V. How to Treat Trees Affected by Sapsuckers?

If a tree has already been affected by sapsuckers, there are steps that can be taken to help it recover. One option is to apply a wound dressing or tree sealant to the holes created by sapsuckers to promote healing and prevent further damage. Fertilizing the tree with a balanced fertilizer can also help improve its overall health and resilience. In severe cases, it may be necessary to consult with a professional arborist to assess the extent of the damage and determine the best course of action.
