Interesting Cockroach Facts!

Most people have a negative view of cockroaches, associating them with very unsanitary environments. While they are definitely not a welcome insect inside anyone's home, roaches are still very interesting creatures based on their unique biology, which has lead to their evolutionary resilience. In fact, the reason they illicit such disgust in so many people is in a large part due to their biology! Read on to learn some interesting roach facts:

Cockroaches carry and can transmit many diseases such as staph, strep, and salmonella. They have also been implicated in the spread of tuberculosis, leprosy, cholera, dysentery, typhoid, asthma, and other respiratory illnesses. Therefore, it is very important to know what steps you can take to deter them from invading your home. The best thing you can do is to keep your house clean and dry, as roaches are attracted to food particles as well as moist, dark areas. Sweeping, wiping down counter tops, promptly taking out the trash, and putting food in air-tight containers are some easy ways to combat this. However, just because you have a roach infestation does not mean that you are a messy person or have a messy house, and sometimes the best option is to call a pest control company for professional help!
