Cockroaches are a common pest that can be difficult to eradicate. They are notorious for their indiscriminate eating habits, and they can breed quickly. They can also carry common disease pathogens, such as salmonella, which makes them a particular nuisance for restaurants, cafes, and other places where food is handled. They can also have a pungent odour when in large numbers and can cause asthma attacks in susceptible people. There are several techniques that can be used to get rid of cockroaches, including aerosol insecticides, toxic bait, boric acid, and keeping surroundings clean.
