Roaches are one of the most commonly noted household pest insects. They feed on human and pet food, and can leave an offensive odour. They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans, particularly in environments such as hospitals.
Roaches have been shown to be linked with allergic reactions in humans. One of the proteins that triggers allergic reactions has been identified as tropomyosin. These allergens have also been found to be linked with asthma.
Some roaches have been known to live up to three months without food and a month without water. Frequently living outdoors, although preferring warm climates and considered "cold intolerant," they are resilient enough to survive occasional freezing temperatures. This makes them difficult to eradicate once they have infested an area.
Due to the grooming habits of roaches, Ecology Care Pest Control have developed roach control treatments that cockroaches pick up on their legs and body then are eradicated when they clean themselves and neighbouring cockroaches, often at the source of the infestation, their nest.
