The Surprising Link Between Household Pests and Allergies

The Surprising Link Between Household Pests and Allergies

Did you know that common household pests can actually trigger allergies? That’s right! You might be surprised to find out that the cause of your allergic reaction could be right under your nose.

Common household pests like dust mites, cockroaches, and rodents are notorious for causing allergic reactions in people. In this blog, we delve into the connection between these pesky critters and the allergic reactions they can cause. And, of course, we give you plenty of helpful tips on how to keep yourself and your loved ones protected.

Signs of an Allergic Reaction to Household Insects

You could be allergic to common household pests and not even realize it! According to the Asthma and Allergy Foundation of America, symptoms to look out for include sneezing, coughing, a runny or stuffy nose, or itchy eyes, nose, mouth, or throat. These symptoms may last for weeks or months and could easily be confused with the common cold. If you have asthma, an allergic reaction could trigger asthma symptoms or an asthma attack.

Unfortunately, some people can have a severe allergic reaction to insect bites or stings, which can be life-threatening. This type of allergic reaction is called anaphylaxis and requires immediate medical attention. Without treatment, it could even be fatal.

Symptoms can affect different parts of the body, including the skin, lungs, heart, and gut. Some signs to watch out for include skin rashes, swelling of the lips, tongue or throat, shortness of breath or wheezing, dizziness, and stomach pain or diarrhea. So, if you experience any of these symptoms, make sure to get medical attention right away!

What Household Pests Cause Allergic Reactions?

We all know how serious allergic reactions to common outdoor pests can be — but what about indoor pests? For many with allergies, asthma, and other sensitivities, common indoor triggers can be just as irritating and even dangerous. Here are the most common household pests that cause allergic reactions.

Dust Mites

You know those little buggers called dust mites? Well, they’re these super tiny creatures that love munching on dead skin cells from people and pets. And they’re everywhere, especially in cozy spots like bedding, carpets, and cushions. Dust mites are extremely attracted to the excess moisture in your home.

Unfortunately, dust mite droppings can cause some pretty nasty allergic reactions, like sneezing, itchy eyes, and a runny nose. If you have asthma, they can make it even harder to breathe. So, it’s a good idea to keep things clean and tidy to avoid these pesky little critters.

To reduce the presence of dust mites in your home, take the following steps:

    • Remove water sources (humidifiers, excessive bathing, kitchen activities).
    • Wash bedding, including sheets, pillowcases, and blankets, in hot water (at least 130°F) once a week.
    • Use allergen-proof covers on pillows, mattresses, and box springs.
    • Vacuum carpets and upholstered furniture regularly.
    • Keep humidity levels in your home below 50% by using a dehumidifier or air conditioner.
    • Replace carpeting with hard flooring, if possible.


Did you know that cockroaches can carry harmful bacteria and viruses that can make people sick? They can even trigger allergic reactions in some people and make asthma symptoms worse. These little critters leave allergens in their saliva, poop, and body parts that can float around in the air and end up on surfaces all over your house. Yuck!

To avoid reactions from a cockroach allergy, take the following steps (while wearing gloves and a mask):

    • Clean your home regularly and make sure to pay special attention to the kitchen and bathroom.
    • Seal up any cracks or gaps in your walls, floors, and foundation.
    • Store food in airtight containers and keep pet food dishes clean.
    • Take out the trash daily.
    • Get rid of any standing water and fix any leaky faucets or pipes.
    • Use bait traps or hire a pest control professional to eliminate cockroach infestations.

Mice and rats can be more than just a nuisance. They can carry harmful bacteria, viruses, and allergens that can cause allergic reactions in people. Their urine and droppings may contain allergens that trigger asthma symptoms in people who are already sensitive to them.

Not only that, but rodents can also bring in other pests like fleas and ticks, which can also cause allergic reactions. So, it’s important to take steps to prevent rodents from entering your home and spreading these harmful pathogens.

To remove and prevent rodents, take the following steps:

    • Seal up any cracks or gaps in your walls, floors, and foundation to prevent rodents from entering.
    • Store food in airtight containers and keep pet food dishes clean.
    • Keep your home clean and free of clutter, which can provide hiding places for rodents.
    • Use snap traps or hire a pest control professional to eliminate rodent infestations.
