Yeah me too. The BT works great. Those little caterpillars will ruin your yeild.
whats BT ? i have worms also how do i get rid of them
whats BT ?
BT is Bacillus thuringiensis is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide (wikipedia)
In short its a bacteria that you spray on the plant… totally harmless to people. Not so harmless to worms and caterpillars. They need to eat a bit of plant to get the bacteria in their stomach, after a short spell the bacteria stops them from being able to eat any further and they starve to death. Unfortunately timing is everything for some worms, the Eurasian hemp borer eats some leaves and the bores into the stalk of the plant once in there it doesnt contact the spray. So the hemp borer is unfortunate to get in your crop. I had it last year, lost over a pound of bud to it. You need to burn any infected plant material. Bt works for most worms and caterpillars its best to start applying as soon as you notice them, apply once a week. You can also use during early flower, but by mid flower its probably too late to stop bud damage.
where do i get this product from ?
Im dealing with caterpillars for the first time. Just picked this up last night and treated the plant for the first time. Planning on doing my first bud wash being a outdoor grow.
I use a spray of good old Castile soap and water - however I don’t have major issues with them thankfully.
Honestly the only strains they have gone after in my garden were purple punch and purple haze. Other plants nearby were left alone - maybe coincidence - maybe my caterpillars just go for the purple - lol.
Anyway a spray bottle with water and 1-2 teaspoons of Castile soap is what I use on leaves, flowers, stems, soil and general area around garden.
You can buy BT in almost every garden store, heck I bet you can get it at walmart.
It is a product made by Monterey. You can get it at the hardware store. It stops them immediately. They can’t eat and then they die in a couple days. Good luck.
I agree. I caught mine at semi late stage and going to spray at day 5-6 again and hopefully saving my crop. Got mine at lowes and a little half gallon pump sprayer. Only mix up what you are going to use in a 24 hour period as directed on the bottle. When it comes to harvest, I’m going to do a bud wash to wash off dust, poop and whatever else before starting to dry in a tent. I’ve always done greenhouse and wated to try something new. Inspect your plant multiple times day if possible and pick off whatever little buggers you find.
thank you
