It's been shown in studies (http://www.bioone.org/archive/0015-4040/88/2/pdf/i0015-4040-88-2-219.pdf) and now I'm seeing it out in the field. Bifenthrin is not killing chinchbugs. Either is a lot of other products. It's making life hard on me and was wondering who else is riding this boat with me. I know I'm not the only one. I've got a couple lawns that I've thrown almost every insecticide at them and I cannot control them. I'm doing more and more retreats every month. Here's a list of applications that have failed to control chinchbugs over the last several months. Talstar 1oz per 1000 Onyx .15oz per 1000 Talstar 1oz/LescoWet1 oz per 1000 Onyx .15/LescoWet 1 oz Dylox 3oz/Spreader Sticker 1oz Cypermethrin .65oz CYpermethrin .65oz/LescoWet 1oz Permethrin .8oz Permethrin .8oz/LescoWet 1oz Talstar 1oz/Merit 3tbsp/LescoWet 1oz Onyx .15oz/Merit 3tbsp/LescoWet 1oz I'm running out of options and losing a lot of money in the process. Sevin is my next option but I've had terrible results with it in the past so I'm sceptical. Who else is having problems? What are you doing about it? What's working for you?
