Causes behind cockroach infestation

We often receive frightened phone calls from households, who are frantically searching for pest control services to get rid of cockroaches. Cockroaches are quite resilient and killing them isn’t always a walk in the park.

There are certain things that invite cockroaches into your home and I think it’s worth knowing about the causes behind cockroach infestation.

The first is of course, exposed food.

Food for cockroaches can be anything from human food to pet food to cardboards. So make sure all you food items are tightly covered and cardboards are sealed and packed properly. If you do find food infested with roaches, immediately throw out the food source. Keep your kitchen counters clean and seal the dry foods in a cabinet or the fridge.

The next would be dark damp spots in your home.

Since cockroaches can go without food, they tend to stay hidden in the blind spots of our houses. It might be the area near the trashcan, or basement, or a certain spot in the kitchen where light doesn’t reach or cluttered shelves and what not. Just make sure you clean all the dingy parts of the house regularly to avoid roach infestation.

Exposed trash is yet another cause behind cockroach pestering.

The wet scraps of food, liquid and cardboard boxes in the trash help the cockroaches to thrive. Keep emptying the bin before it overflows and clean the bin and the area around the bin to keep the bugs away.

Another reason for cockroach infestation is weed overgrowth.

Overgrowth of weed in the garden or near your main pathway attracts these ugly pests into houses. Natural mulch or festering vegetation is quite favorable for cockroaches to survive. Uproot the weeds and keep areas around the door and your pathway clean to inhibit roaches from coming inside the house.
