I'm using the Montery's Garden Insect Spray on my houseplants to get rid of a thrips issue and cant' seem to find whether I could use the concentrate in a soil drench solution or not. I also saw sites mentioning spinosad granules but I can't seem to find those in the US.
Can I go ahead and use the same solution as a soil soak (ratios according to instructions)?
Any recommendations on where to find granules if not?
Note: I know the instructions don't mention houseplants for use but from what I read it seems ok. I tested on a leaf and took my plants outside to spray/dry etc. Thank you!
