I have a thrip infestation. I have been using copious amount of Captain Jacks Dead Bug Brew but it has not worked. It worked perfectly in the past but for some reason not this time. mist it all over the tops of the plants and this time I caked the whole room. Should I also be spraying it under them? Is there some technique to it? Or some times it it just too bad to fix? Could lady bugs possibly help? Thanks for the help!
