BonideCaptain Jack's Thuricide BT, 128 oz Ready-to-Use with Sprayer, Kills Worms and Caterpillars in Home Garden, For Organic Gardening

works great! Keeps my worms and plants safe from other bugs and they live unbothered by the spray. I spray once a week and only spray the amount I think I need to use. I have used this for my plants as well, but mostly on their soil. I haven't sprayed them directly with it other than maybe by accident? I haven't noticed any issues, when it does dry it may leave soil a little crunchy looking, just water and mix the top before you spray again and everything looks fine!

Sprayed this on my tomatoes and herbs, once I started seeing Hornworms. They dried up like a booger, did not have any troubles after that. Easy to apply using a disguarded cleaning spray bottle.

I religiously was out every weekend spraying the Gypsy moth sacks on the trees in our yard. Of course I couldn’t reach to the tops of the trees, but I did my best to get as many as I could. We didn’t have anywhere near the amount of them as we did last year. I will buy this again for next year….if I see they are coming back.

Worked great killing caterpillars on the boxwoods. Hand pump is a bit tedious for large areas. Best use a pressure sprayer to save your hands for all the pumping. Overall great product inside the bottle.

I used this to kill the bag worms in my arborvitae. They were infested, and I needed something that wouldn’t harm all the birds that nest in them. I have 17 of these trees and I was terrified of losing them. I did some research and read great things about this product. It was a lifesaver for my trees. You still must pull the bag worms off the tree FYI. Now I use it preventively and spray the trees in June and again in July.

With the colder weather arriving my wife has moved her plants inside for the winter. Along with them came an army of flies and gnats. The yellow pests traps and bug sprays take care of the visible bugs but there seemed to be an endless supply of them. We gave Captain Jack's BT a try and within 2 weeks we've pretty much eliminated the problem. Spray the soil in the plant containers and it takes care of those nasty new arrivals for you. I bought the larger size this time (better deal), which I'll use to refill the smaller bottles she uses around the house. This worked really well for us!

I have a severe leaf roller infestation in my canna this year, and I constantly battle army worms in my vegetable garden. This definitely seems to be helping both! But unfortunately, the sprayer handle completely broke off in my hand when I was trying to use it today. To make matters worse, the way the sprayer broke apparently made the product leak so 80% of the bottle leaked all over my porch before I noticed. This stuff is way too expensive to waste like that!!! If I was to order this again, I would immediately put it in a different container.

Being a gardener I have struggled with horn worms on my tomatoes. Yes I have used most everything to prevent horn worms. This is the first product I have used that works beyond belief. Must try this!
