Customer Question

Hi. We believe we have Chinch bugs in our yard, which are killing our lawn. Additionally, our German Shepard has been itching like crazy. It appears the bugs may be biting her, too.
If we treat the lawn, is the pesticide toxic to our dog? And how do we treat the dog?

Gina, please see here:

These bugs will bite dogs (and you) if contacted by them but don't colonize either your dog or you and so treating your dog isn't necessary unless she's hypersensitive to the bites and her pruritis (itchiness) would benefit from the administration of a short-acting corticosteroid such as prednisone. You'll note that there are non-insecticide approaches to these bugs as mentioned in the article but if you choose to use an insecticide, you'll need to wait until it's completely dry before allowing your dog out on the lawn. It would be prudent to wash her paws down after re-entering your home (or thoroughly bathing her if she rolls in the grass) for a week after the insecticide has been applied. Insecticides containing bifenthrin - a pyrethroid that's well-tolerated by large breed dogs - should be considered.

Please respond with further questions or concerns if you wish.
