That's impressive & interesting that they got tapes to come out that way as those bugs are very tenacious. The only thing is, passing some & killing all of them ain't necessarily the same thing. And all it takes is one pregnant one to keep things going. So I say eat leafy greens - the best thing you can put on your plate - but I'll take a side dish of herbicides & a zapper in maintenance daily. Takin' no chances.
