found new bagworms today

Location: Ankeny, IA
Size of bag: 1/4 inch
Host plant: low-growing junipers about two feet tall that were heavily damaged last year from bagworms

We plan to wait a week or so before bagworm spraying cuz they don't all hatch on the same day.

Choice product for 100% kill: Talstar.

Anybody else seeing them yet in the upper Midwest?

(also found fall webworms yesterday on Mulberry trees)

rscvp, thanks

Larry,
Bt works well on bagworms at this stage.

i have seen none, but i am sure i can find them if i look deeper. i plan on spraying shrubs and small trees on monday. i am later than i wanted, but so far not much damage on plants this year, but i think it is coming from both worlds(insects and fungus), i also use a surfactant, do you guys? my mix is insectandfungus fro both summer apps and and additional insect late summer. surfactant with it always . so, do you?

Have them in my spruce this year, heavily damaged before we noticed.

Pics in my tomato thread, probably on the second page now in this forum.

Thanks Barry -- I didn't know bt kills 'em. My situation is that I like to spray just one time & offer a 100% kill for customers. This is why I will wait a week or so to begin spraying, cuz they don't all appear at the same time. I prefer to wait until the smaller bags are about 1/2 inch & larger one's are nearly an inch long. It seems this way, all have hatched out, and I can attain the 100% kill.

Thanks grassman -- I never use a surfactant. I use Crosscheck (LESCO) which is the same as Talstar.

kirk -- Thanks, I'll check it out.

I sent an email to the head entomologist at ISU Friday to get his opinion as to how long to wait before spraying. I told him my concern was that more will continue to hatch in the upcoming days.

Keep in mind that I've personally been spraying bagworms (Texas) since 1979, and the boys at ISU have not had these decades of experience cuz bagworms have been working their way further north in recent years. Yet, I like to get their input too.

I HATE THOSE THINGS!!!!


What is the best thing to use to prevent them? I have been using Seven (liquid) and spraying plants that they love to eat, will that work?

Morgana -- I used Orhtene back in the 70's/80's (ChemScape), but Talstar (Crosscheck from LESCO) works even better. No surfactant needed.

GREEN-UP ... Good deal. Here, it's about a 3-week window for best results (100% kill).

IMO high pressure (w/J-D9 or tree rifle) at a minimum of 400 psi is the key. Especially on evergreens, cuz evergreens require more spray than deciduous plants for thorough coverage.

Spraying too soon = not all will die. Spraying too late = not all will die.

Is Talstar or ChemScape harmful to dogs and cats?
