Hi,
I first noticed bagworms on my blue spruce and pine trees last fall. There were a limited number and I was able to pick off most of the sacks. Now it is spring and I feel I should take some precaution against them because I know there are more I either can’t reach or have missed. My concern is that three trees are tall. One tree is about 20 feet tall. What kind of sprayer do you recommend for tall trees? Do I need a professional to do these trees? If so, what do I ask for? In other words, should I go with one treatment and wait to see if I get more infestation before I have them sprayer again? Of course, I am looking at the least expensive way to treat. Right now there is one bagworm out of my reach from last year and it is driving me crazy. Any suggestions? I know I can treat the small shrubs myself but the tall one concern me.
This is an easy one. Once any tree has bagworms, the best control method is to spray it down in the fall and following spray with some BIFEN. If you treat early spring, the residual should get the larvae as they emerge. Bifen will remain active for 3-4 weeks no problem. To be sure you get them all, treating twice is advised.
To reach high up, get the TROMBONE SPRAYER. This will easily spray 20+ feet and when you’re standing and spraying, there is no problem reaching 25 feet high.
