Imagine you just found several roaches in your fridge. What shall you do?

I guess it's about time to clean the fridge!... Make sure you clean it properly once a month. Pay attention to food that got rotten. Use your nose and eyes, otherwise the roaches will be attracted (to the rotten food and food stains ;) ). And if they're not only in the fridge, but also in the kitchen, call a team that kills roaches. I only don't know how they're called in English..
