As a homeowner, it is essential to take the steps necessary to protect your family and your pets from any pests that may invade your home. Many household pests are more than just a nuisance. Many can spread a number of serious diseases that can affect your family’s health and overall well-being. Here are just a few that you will need to be aware of.

Cockroach-Borne Illnesses

Cockroaches are one household pests that many people shudder at the thought of dealing with an infestation. There is a good reason for that. Cockroaches are attracted to clutter, and can often be found in a messy home. Cockroaches can transmit several illnesses to people, and even aggravate breathing issues for people that have serious asthma or allergies. Most of these diseases are spread when the roaches crawl into your food and contaminate it or as they crawl over your dishes and utensils.

  • Typhoid Fever—This is a serious illness that begins with the onset of a high fever. There may be abdominal pain, headaches, and constipation as well as a rose-colored rash. After a week, the person may be too tired to move much, and at this point, diarrhea may set in. It is important to seek treatment for this if you suspect you may have it.
  • Salmonellosis—This is one of the most common causes of diarrhea in the United States. It is spread when people eat contaminated food. Cockroaches will spread this because they can carry it on their legs or bodies and then deposit the bacteria in your food.
  • Dysentery—The main symptom of dysentery is severe diarrhea that can include stool that has mucous and blood in it. This is spread through contaminated food and water and needs to be treated by a doctor for the patient to recover.
  • Cholera—According to the World Health Organization, Cholera is a serious illness that can kill quickly if not treated promptly. It is a form of watery diarrhea that can cause people to die from dehydration. Treatment includes keeping the patient hydrated while the disease runs its course.
  • Listeriosis—This is another disease that can cause diarrhea. It can also cause headaches and muscle aches. It is mild for most people, but it can cause pregnant women to miscarry and poses a threat to people with a weakened immune system.

    Most pests come into your home in search of food and water, as well as a warm place to stay. If they do not find food or water, they will need to live. Doing your dishes after each meal and cleaning up any crumbs can help deter cockroaches and ants. As will taking out the trash each evening.

  • Seal the Entrances of Your Home

    Check around the doorframes and window frames of your home to make sure they are sealed tightly. If necessary, you may need to caulk any cracks that you do find. Be sure that the doors fit snugly and that there is no room for an insect to come in.

  • Check the Exterior of Your Home

    Look for holes or cracks in the foundation or under the eaves of your attic. Fix any that you find. Check to makes sure any vents into your home has a vent cover that will keep insects and rodents out. Cut back any branches that may be handing over the roof of your home, since this can provide an easy access point for pests.

  • Apply a Barrier Treatment

For many insects, you can stop infestations by regularly treating the exterior of your home. An exterminator can apply the treatment periodically and it will stop bugs before they get into your home.
