Having allergies can be rough. Commonly, folks blame their sneezing, stuffy nose and red eyes on pollen and dander. But those may not be the only reasons for those “Achoos!.” Common household pests may be to blame, or may make seasonal allergies even worse. Let’s take a look at which household pests can aggravate your allergies.
Pests Most Likely to Aggravate Allergies
You know certain insects, such as bees, wasps, and mosquitoes, can set off allergic reactions with a bite or sting. But these four household pests only have to be around your home to trigger congestion, itchiness, and even asthma episodes.
A cockroach allergy may be more common than you’d think. The National Pest Management Association (NPMA) says that 63 percent of homes — and 78 percent of city homes — contain evidence of cockroaches. It’s not one type of roach, either: There are eight common types of cockroaches that can be found in homes.
Besides making your skin crawl at the very sight (nay, thought) of them, roaches carry diseases, bacteria, and parasitic worms. In addition, they may spark allergic reactions or trigger asthma symptoms.
When breathed in, dust mixed with roach saliva, droppings, and body parts can lead to the following symptoms:
- Skin rashes
- Congestion, runny nose, or postnasal drip
- Ear and sinus infections
- For asthma sufferers, coughing, wheezing, chest tightness, or pain
- Itchy, red, or watery eyes
2. Dust Mites
Thousands of microscopic dust mites feed on the dust around your home. This includes your floors, window sills, little-used furniture, and your bed. Dust mites’ excrement and shed body parts can trigger allergic reactions.
Dust mites allergy symptoms include:
- Watery, itchy eyes
Dust mites also can induce asthma attacks, and are the predominant cause of allergic reactions in asthmatics. In hypersensitive people, dust mites can bring on acute attacks of bronchial asthma. This pest may even be why many children develop asthma in the first place, allergists believe.
Besides spreading disease and destroying property, mice, rats, and other rodents can trigger allergies. The main source of allergies to mice? Urine that contains pheromones, which helps them attract mates.
Rodent dander and saliva also can initiate allergic reactions. Signs of allergic reactions include:
- Itchy nose and throat
- Rashes and hives
- Asthma attacks
- Allergic bronchitis
Rodents aren’t just an urban-area problem, as they also are found in suburban and rural homes. According to the National Institute of Environmental Health Sciences (NIEHS), 82 percent of U.S. homes contain mouse allergens.
4. Fruit Flies
Often mistaken for gnats, fruit flies swarm around ripe and rotten fruits and other foods.
There’s no need to worry about fruit fly bites: They don’t have teeth. But some people get itchy red bumps and rashes should one land on them. Also, a 1986 study showed that exposure to fruit flies can set off respiratory symptoms in some people.
How to Know if You’re Allergic to Household Pests
If you’ve been exhibiting allergic symptoms for more than a season, it’s time to see an allergist. Before determining a treatment plan, your allergist will test to see what will trigger your allergy symptoms.
Skin prick test. This test, usually done on the forearm in adults, will check your response to 50 different substances at once, including:
- Dust mites
- Pet dander
Skin injection test. Your doctor will inject a bit of allergen extract into your skin; a reaction should be present within 15 minutes. This test is usually used to determine a penicillin or insect venom allergy.
Patch test. A patch containing 20-30 allergen extracts is placed on your skin and you’ll wear it for 48 hours. This test is generally used to determine if a substance causes allergies to skin.
How to Get Rid of Household Pests and Their Allergens
Getting rid of household pests can go a long way toward easing your allergy symptoms. A good way to do that is to adopt an integrated pest management approach for your home. This works by making your home less appealing to pests.
How to Get Rid of Cockroaches
Removing food and water sources will discourage roaches from taking up residence. A few steps:
- Wipe off counters and tables after food prep and meals.
- Sweep the kitchen and dining room floors regularly.
- Keep trash in closed containers.
- Repair leaky faucets and pipes.
- Don’t leave standing water in the sink for long periods; change pets’ water bowls frequently.
If you need a pesticide: Cockroach baits can be effective. They eat the poison-laced food contained inside and share it with others in their nests, killing them at the source.
How to Get Rid of Dust Mites
The bad news: You’ll never completely get rid of them. However, you can lessen their numbers. A few things you can do:
- Clean surfaces: Wipe down furniture with a damp cloth.
- Vacuum carpets and upholstery and sweep floors often. (Some experts suggest
replacing carpet with vinyl or hardwood floors.)
- Place mattresses, box springs, and pillows in a plastic cover that seals off allergens. And keep pets off the bed.
- Wash fabrics (slipcovers, bedding, curtains) often.
- Consider HEPA filters for your HVAC system. And change furnace filters regularly.
If you need a pesticide. Sorry, but conventional pesticides don’t work on dust mites. Studies have found that benzyl benzoate will kill dust mites, but not for long.
How to Get Rid of Rodents
Removing food and water sources help get rid of mice, too. But it’s also important to seal off entry into your home. A few places to check and seal off:
- Crawl spaces
- Pipes to and from and washing machines, hot water heaters, and furnaces
If you need another method:
- Spring traps are a quick and humane way to dispose of mice. Place where mice are likely to travel.
- Bait stations contain poisonous blocks or pastes that kill mice. Be aware that if the mouse eats the poison, it likely will die somewhere else in your home (and leave an awful smell).
How to Get Rid of Fruit Flies
Like roaches and rodents, the best approach is to make your home non-welcoming and prevent fruit flies from appearing in the first place. A few things to try:
- Don’t leave out food. Put produce in the refrigerator or cover it.
- Don’t leave out partially consumed sweet drinks.
- Keep trash and garbage in covered containers.
- Rinse items before putting them in the recycling bin.
- Sweep up crumbs and mop up spills from floors.
If you need a pesticide: Products containing pyrethrins can be effective, but can irritate skin and eyes. It also can be toxic to pets.
There are several methods; this one is simple and effective:
1. Fill several juice glasses or small bowls two-thirds full of cider vinegar.
2. Add two drops of liquid dish detergent to each glass, then mix.
3. Place where flies like to congregate. The detergent cuts the surface tension of the vinegar, so the flies will sink (and drown).
It’s possible. According to a 2010 study, mice became fearful when they smelled a compound secreted by cats (and other predators). And some cats will run off mice, or … er … dispatch them. However, mice can always find a cat-free zone to nest in. Or your cat might prefer hunting catnip mice to the real thing.
If you are considering a feline mouse deterrent, be sure no one in the house has a cat allergy. Also, be mindful about where you place Ninja’s food and water: You don’t want to bring in another type of pest.
The Asthma and Allergy Foundation (AAFA) offers some allergy-friendly cleaning tips:
● Open windows and run fans while you clean.
● Use a damp cloth to remove dust or a cloth that traps dust. Dry dusting can spread allergens around the house.
● Use a vacuum with a HEPA filter. Watch air flow, since some vacuums can push allergens back into the room.
● Take a shower and change clothes after cleaning. If you wear glasses, clean them, too.
● Reduce clutter
If you’re severely asthmatic, always check with your doctor about how to safely handle cleaning chores.
