Yes, they're a pain in the ass. Diatomaceous Earth keeps the numbers down to where they don't do any real damage, and you can use it right up until harvest, just don't get it on the buds because it will stick to them. I have thrips and I haven't bug bombed becasue I grow tomatoes and peppers indoors and believe it or not they pollinate the fruit... but the DE plus neem oil keeps everything under control.
