funny. both years i have done outdoor. i had some chewers on my plants. in both cases, the plants finally "defended themselves"......and the problem left. the plant soon grew faster than the bugs could hurt it. also, i had a simple potatoe bug in my indoor. did not eat enought to hurt a thing. but enough for me to tell i had a chewer. i finally set off a bomb. next day, it was upside down. last week, i spread a product called "spectracide" on my lawn. bugs have a hard time getting in the house, if they die from first comming on the property. lol. should be an easy year for this. also, if u shy from this aproach, then get some mantis egg cases. they are not only helpfull, but fun. and cool pets!!
