Cockroaches thrive in areas where there are dark, cool, damp locations where they can nest during the day and have adequate food available for nighttime feeding. So, cockroach infestations are common in bathrooms, kitchens, and other areas of the home that provide adequate food and protection during the day. Prime locations for cockroaches to be found are under sinks, refrigerators, and water heaters, in wall voids, and around leaking pipes.
To control cockroaches, ensure all food sources are removed or sealed in glass, steel, or heavy plastic containers. Do not leave food scraps or pet food out overnight. Fix leaking pipes, and close cracks and openings in and around baseboards and pipe fittings.
Dust all potential daytime resting areas with Diatomaceous Earth, including under refrigerators, under sinks, etc.. Place Victor Roach Magnets throughout the infested area, to both reduce the population and monitor for future outbreaks.
