While some pests may only be considered a nuisance, many can cause serious health problems. Below are three of the most common household pests and how they can affect your health.


These small, flat, oval-shaped reddish-brown insects typically live in mattresses and other parts of the bed. They feed on human and animal blood mostly at night. Their bite can lead to itchy welts and rashes and even cause anxiety and sleep deprivation for their human hosts. Cleaning, scrubbing, or vacuuming your bed can help eliminate these insects. However, if there’s already an infestation, professional pest control measures such as bed bug extermination using heat treatment may already be necessary.


Though only female mosquitoes need blood from their human and animal hosts, these flying insects have been responsible for spreading various deadly diseases. They accomplish this by picking up a virus or parasite from an infected host and then transmitting these to their next hosts. Malaria, Zika virus, and yellow fever are just some of the serious diseases transmitted through mosquito bites. Keeping your garden well maintained, disposing of stagnant water, and disinfecting can help reduce the breeding sites of mosquitoes.


Rats and mice are probably the most feared and unwanted kind of house pests because of not only their destructive habit of chewing on things (including your food) but also the diseases they carry. Serious infections, such as leptospirosis and salmonellosis, are spread through their droppings and urine. Also, their bites and scratches can lead to rat-bite fever. Aside from keeping your surroundings clean, you can get rid of rodents by using traps and baits.

More than being a nuisance, household pests can cause you serious health problems. This is why you must do everything you can to protect your homes from them.
