What to do

- Store food, including pet food, in sealed containers rather than bags or boxes.
- Take out trash regularly and rinse recyclables before storing them.
- Fix any leaking faucets or pipes under the sink, since roaches need a water source to survive.
- Seal visible gaps around pipes, baseboards, and behind appliances with caulk.
- Place roach bait stations or gel bait in areas of activity, particularly under the sink, behind the fridge, and near the stove, rather than relying on sprays alone.
- Call a pest control professional if roaches are seen during the day or the population doesn't shrink after a couple of weeks of baiting and cleaning.
