German cockroaches are the ones that ruin a kitchen. They live in the warm spots you cannot see: behind the dishwasher motor, inside the fridge cavity, up under the bench overhang, in the gap beside the oven. A surface spray across the floor does almost nothing to them. Gel bait placed into those harbourage points works, because the ones that feed carry it back to the rest. Australian and smoky brown cockroaches are a different job. They come in from outside through drains, weep holes and around the metre box, so that treatment goes around the perimeter.
Kitchen prep makes or breaks the result. Crumbs under the toaster and a wet sponge in the sink will outcompete any bait on the market. We tell you what to clear before the visit and what to leave alone, because wiping down the treated spots afterwards throws the whole job out. In units and townhouses around Geelong, roaches travel between properties through shared walls and plumbing risers, so one flat can get reinfested from next door. We say so upfront rather than treating the same kitchen twice.
