We do not offer a product that can be applied inside the dishwasher for roach control. You will want to keep it dry after each use and apply products in the Roach Control Rotation A Kit in the kitchen for treating roaches along with non-chemical methods. Please take a few moments to review our treatment article on How to Get Rid of Roaches for a successful eradication program.
