purple robe tree borer control


How do I treat purple robe tree borers and what product do I use to treat the tree?

There are two ways to treat.

Eggs hatching in the spring will bore into the trunk and as they bore, you’ll start to notice a white colored wood dust accumulating on the bark. Their holes will be 1/4″ to 1/2″ wide and several inches thick. Treat any you find with PT-CYKICK AEROSOL. It will quickly kill feeding larvae and with the included straw injector, the task will be easy to complete. Basically it should take just 2-3 seconds per hole.

Next, spray CYPERMETHRIN over all sides of the trunk along with any low lying limbs. This will kill hatching eggs as spring arrives. The Cypermethrin will also repel egg laying females who will be coming around from mid summer through fall.

Use a good HOSE END SPRAYER or PUMP SPRAYER to apply the Cypermethrin.

As for when to spray; use the Cykick any time you find active holes. This will be most common from spring through early summer but can be later in the year depending on what part of the country you reside. Use the Cypermethrin from early summer through fall spraying once a month. Its important to renew the treatment monthly for the first 1-2 years of discovering a problem because once a tree has activity, it tends to attract more adult females to lay eggs. So unless you keep treating with the Cypermethrin, the problem will continue from year to year.
