Thanks guys. BTK is a concentrate that is meant to be applied to foliage, but it is a very useful soil aid. It makes 30 liters of non-concentrate solution, and (BTK & mosquito dunks ) control(s) a variety of pests including leaf rollers, fungus gnats, thrips, caterpillars, gypsy moths, spring and fall cankerworm, Spruce budworm, Jack Pine Budworm and many other insects especially those that lay eggs in the soil for their offspring to hatch into larvae.
For very aggressive pests that will not go away, Pyrethrin is a suggested solution. You should use caution when using pyrethrin, permethrin, tetramethrin, or anything that ends in *methrin. These do not have any known side effects on humans or most mammals except for permethrin, which has been found to cause feline sickness and death.
Permethrin is the same chemical that they use to kill lice and ticks on dogs, and as said by most vets, keep your dog away from your cats!!!
As a preventative method, a lot of professionals use a combination of insecticidal soap, neem and btk MIXED TOGETHER to control a possible outbreak. Most don't have to worry about this issue unless you're growing a farm of plants. But remember, it's a LOT easier to prevent an insect invasion than to consistently maintain it!!! We all live busy schedules, so lets get rid of these pricks for good
