Asp Caterpillar

I am starting to get them on my pear trees. I’ve done a search on the internet and that really don’t have a lot of suggestions on what to spray to kill them. I don’t want to kill anyone beneficials but I don’t want them spreading either. They are worse than getting stung by a hornet if you accidentally brush against one. Has anybody ever had any luck getting ready of them?

Can you be more specific? We call many little worms a caterpillar but none of them bite.

I think TS refers to these insects:

They don’t bite but they are venomous.

Oh sorry I get it. I thought ASP was a typo for ASAP or something else.
I would spray all the stuff I have on them and see if they die! LOL!

You might try BT to keep it organic. If that doesn’t do the job try something stronger.

Speaking of organic and moth pests, you can use either Bacillus thuringiensis (Bt, aka thuricide, aka Dipel, aka etc…) or spinosad (Monterey Garden Insect Spray, Captain Jack’s Deadbug).

The activity of those two chemicals is primarily specific to moth larvae.

If they eat foliage, then either could work. Spinosad seems to work well on leaf-rollers. I use both in combo for codling moth as they don’t eat much foliage/fruit skin before eating into fruit, so I figure two toxins are more likely to kill than one.

Most moths have a weakness but I don’t know their weakness yet. I would start by counting on moths drawn to light https://www.amazon.com/dp/B00004R9VZ/ref=asc_df_B00004R9VZ5039820/?tag=hyprod-20&creative=394997&creativeASIN=B00004R9VZ&linkCode=df0&hvadid=167127504138&hvpos=1o1&hvnetw=g&hvrand=17773566607465264567&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=1014485&hvtargid=pla-310412942774
.Have no way to know if it would work but I’ve never seen a moth not attracted to light. For the ones on the plants that can’t fly I looked at this http://extension.colostate.edu/topic-areas/yard-garden/backyard-orchard-apples-and-pears-2-800/ and this http://citybugs.tamu.edu/factsheets/biting-stinging/others/ent-3010/ I would hit them hard by spraying them with permethrin if it was my orchard. I can’t give you advise on what would work best for you only say what I would do for my own since I’m not an expert rather just a orchardist!

I will try the BT and see if that works. It seems that some people have had luck with it.
