FAGUS INSECT PROBLEMS
Borers such as flat-headed apple tree borer or two-lined
chestnut borer bore into trees weakened by some stress.
Prevent the insect infestations by keeping trees healthy
with regular fertilization.
Regular inspections of the trunk and branches are
suggested for early detection of scales. Control scales
with properly labeled insecticides when the crawlers are
active. Identify the specific scale involved to time the
sprays properly.
Certain caterpillars can be controlled with sprays of
Bacillus thuringiensis. Insect identification allows
proper spray recommendations to be made.
