I need more information to answer your question accurately. Which Talstar granules did you use? Which Amdro product did you use? You are welcome to give us a call at 866-832-6240 as well.
The only systemic insecticide that we are aware of that is labeled for bagworms is Bonide Systemic Insect Control with Acephate but it is only labeled for use on shade trees and you must spray all of the foliage to get the desired results.Below you will see what we usually recommend for bagworm control.
Bagworm recommendations:
It is important to start control methods before a major infestation occurs. Once the bagworms have matured and have formed the "bag" most chemical control methods will no longer work.
You can manually control bagworms by simply plucking them off of the infested trees and dropping them into a bucket of soapy water or squishing them. This control method is most useful during fall, winter and early spring, before the eggs inside the bag have hatched.
Chemical control may be achieved when the larvae are small and just emerging from the over-wintering bag. Use a concentrated liquid insecticide such as Talstar or Tempo. Foliage should be thoroughly wetted with the insecticide spray in order to achieve thorough coverage. When doing an insecticide treatment, timing is key. To find out the correct time of year to treat for bagworms in your region contact you local Cooperative Extension office. These offices can prove to be invaluable when treating for insect pests.
Talstar did come in an aerosol can, Talstar Aerosol, but has been discontinued by the manufacturer.
We have put together an Overwintering kit that is just for stink bugs. This kit includes Demon WP insecticide with Cypermethrin, Eco PCO dust and a hand duster for easy application. You should treat once a month through November for best results.
You can prevent ants, flies and other insects from entering your home by applying a long lasting residual product such as Talstar. Talstar kills over 75 different insects and is safe to use indoors and outdoors, is gentle on plants, is odorless, dries clear, leaves no stains, is non-irritating to the skin, and won't break down easily with rainfall. We also suggest you use Integrated Pest Management or IPM. IPM is a step by step approach that helps you identify the pest and determine why that pest is there, and then determine how to exclude the pest in the future. Please read the IPM article to learn how to successfully stop pests before they become a problem.
