Where Are Cockroaches Found?

Cockroaches come from regions that harbor bacteria, like bathrooms, drains, and dumpsters. They feed on garbage, breed in sewage, and excrete waste over every surface they touch. Cockroaches are excellent hiders and especially favor moist and restricted areas. Cockroaches are thigmotropic so they need to sense contact on all sides of the bodies. As a result of this, cockroaches are generally found nesting under sinks, in wall cracks, in drains, around water heaters, behind appliances, in cabinets and pantries, beneath piles of cardboard and paper, and beneath undisturbed furniture.

5 Tips to Avoid Cockroaches This Winter

Winter can be a tricky time to get cockroaches. While they are adapted to thrive in hot temperatures, these cold-blooded pests cannot survive environments which are too hot or too cold. In actuality, some species stop growing and replicating when exposed to colder temperatures, usually consistently below 45 degrees, for long periods of time. As temperatures fall, roaches will find shelter in warm areas, most frequently in our homes and offices. These buildings give them everything they need to survive the winter – heat, accessibility to water, and an abundant source of food.

Prevention is key when it comes to roaches. Here are five tips to prevent cockroaches from taking over your house this winter.

Clearing out clutter eliminates areas roaches can use to conceal. Keep rooms clutter free and dusted frequently. 

Use plastic storage containers with lockable lids versus cardboard boxes. Eliminate cardboard and papers altogether as roaches like to breed in these substances.

Roaches get into houses under doors and through cracks. Identifying these and sealing them up helps remove points of entry for cockroaches and other insects.
