Common complaints that people make about pests are that they chew away at food and destroy furniture. But that’s not everything that they can do that can ruin your life at home. They can also spread dangerous and potentially deadly diseases throughout your house.

Just like with the food and furniture, these can eat away at your finances and interfere with your daily activities. What’s worse is that they can even lead to your death. Here are but a few of the common ones that you may encounter.


This is a common disease that’s carried by mice and is spread into the water via their urine. Symptoms of the illness are chills, vomiting, nausea, and loose bowel movement which can lead to further complications such as extremely high fever or, even worse, death.

This is normally contracted by people when contaminated water comes into contact with open wounds or is ingested, so be careful when swimming in fresh waters, wading through floods, or engaging in water-related sports such as kayaking. You can avoid this in your home by calling residential pest control service providers in San Juan to conduct regular checks for rat infestation.


This is one of the illnesses that are usually associated with food poisoning and can even be lethal when not treated immediately. It’s usually contracted when someone eats contaminated or improperly cooked food.

Those who are unfortunate enough to have this disease start to develop symptoms such as diarrhea, vomiting and high fever. Aside from uncooked eggs and meat, droppings from cockroaches and rats are the most common sources of Salmonella, and this is a reason chefs take good care to keep their kitchens pest-free.

Eliminating those creatures from any place of food preparation isn’t just because they’ll ruin the aesthetic otherwise.

One of the most feared diseases in the world today, dengue has no antiviral medicine or vaccine as of date. Afflicting both adults and children alike, this illness carried by the Aedes mosquito is so dangerous that all four strains of it are potentially lethal.

Watch out for signs such as rashes, muscle, and joint pains, as well as a severe fever, as these warn you that the person with those symptoms could be infected. Whether you see those mosquitoes around or not, it’s best to call in pest control services to limit their population in your immediate area.

At this point, you may realize that it’s in your best interest to keep your home free of pests. They not only bring damage to your house and belongings, but they can also ruin the state of your health as well. Prevent them from doing any of these harmful activities by maintaining the cleanliness of your home as well as enlisting the services of pest control experts.

You might find it costly for now, but you’ll be thankful when you avoid making a bigger dent to your budget through medical bills. In this case, prevention is a much better choice than a cure.
