Help infestation on my cedar bushes
Hi recently and for the first time we have a sort of cocooned active worm
all over our cedar bushes and they seem to be killing the bushes. They look just like dead growth on the bush but are actually little worms in a tough little bag. Anyone know how to kill the little suckers. I am already aware of the flamethrower option so no need to mention it. Thanks in advance |

This link should help explain the problem and offer suggestions for control: http://www.ces.ncsu.edu/depts/ent/no...1e/ort081e.htm pam - gardengal |

Thanks Thankfully, no bagworms in this neck of the woods, although we have plenty of other equally nasty pests. I think David Bockman, who posts here often, has had experience with them..........David, any tips for Chris?? pam - gardengal |

Help infestation on my cedar bushes
It's disgusting, but I handpick (wearing gloves) and drop them in a bucket
of water... for very large infestations (and to reach where a ladder can't) I've used malathion with excellent results. I use an alternating schedule of spraying like this: spray 3 day interval spray 7 day interval spray 10 day interval spray if needed Dave "Pam" wrote in message ...

They look just like dead growth on the bush but are actually little worms in a tough little bag. Anyone know how to kill the little suckers. These are bagworms which are actually moths. The females are wingless. A neighbor who is a member of the Lepidoptera Society (bagworms are members of the LEPIDOPTERA family) says he has tried contact insecticides and they were not effective. His best results have been using systemics like acephate (Orthene). Malathion didn't work for him. Carbaryl is not good to use on conifers since it kills the parasites that control spider mites and spider mites are real bad on conifers. Bacillus thuringienis (Dipel) is non-specific and kills most LEPIDOPTERA. We have bad attacks of bag worms on juniper (red cedar), Colorado Blue Spruce, and arborvitae. It has killed large parts of a globular arborvitae which I hope to save. -- Pardon my spam deterrent; send email to Visit my Rhododendron and Azalea web pages at: http://home.earthlink.net/~rhodyman/rhody.html Also visit the Rhododendron and Azalea Bookstore at: http://home.earthlink.net/~rhodyman/rhodybooks.html Cheers, Steve Henning in Reading, PA USA http://home.earthlink.net/~rhodyman |
