Question
QUESTION: I have found bag worms on 1 tree and sprayed them yesterday as I was told with insecticide. Then pruned all the discoloration branches and leaves. And for some reason the say is leaking from the main trunk.  Is this tree going to essentially die.  Own 6 in total all about 2-5 ft. tall only 2 are in the same place and all got treated Help!

ANSWER: During the growing season conifer trees if pruned will exude sap from the pruned ares. This is normal. The tree is using the sap to seal the pruning wound and the sap flow will stop and will not hurt the tree. For bagworm control it was not necessary to prune the branches. The trees more than likely would have put out new leaves. In the future I would pick the bagworms off if the tree is small enough to reach or use an insecticide but not prune during the growing season and that way there will be no sap.

QUESTION: unfortunately the sap is coming from a place where no pruning was done. I just cut off the dead leaves and left the branches with the rest of the green leaves on them.  The sap appears to be coming from a whole the worm created. How often should i treat? Treated on the 23rd and how may times during the course of the growing season?

Answer
If the insect was boring into the twig or branch it was not bagworm--they eat the foliage only. I would guess it was a twig borer of some type. Since I do not know what insecticide you used it would be impossible to tell how long it will last. Some insecticides are contact insecticides and have a life of only a couple of days while others have a residual life of several months. a newer insecticide for insects in the twig is Bayer Advanced or Merit 75WSP  which are soil applied insecticides that will get into the trees system lasting several months. If you just sprayed I would wait and see if additional sap comes out if so then treat again.
