These Nevada Allergens Are The Most Prominent

Between ragweed, grasses, mulberry, and olive trees, it seems that Las Vegas allergies are everywhere! Each year, hundreds of plants and trees bloom from spring through fall. While this means that your backyard is full of lovely colors and wonderful scents for months, it also means that if you suffer from allergies, you’ll have to brace for seasonal symptoms. If you find that your eyes itch, your throat tickles, and you can’t stop coughing when the buds start to bloom, it’s time to find the underlying cause.

Sometimes, you can tell which plants, trees, or shrubs you’re allergic to based on when you develop allergy symptoms, as not all allergens bloom at the same time. Allergies can also be affected by the environment, such as temperature fluctuations. High winds can also be problematic for allergy sufferers, as they can make pollen grains and spores travel faster through the air. If you’re wondering what’s to blame for your misery, here are some of the most common culprits in Las Vegas.


You might know mulberry for the delicious, beautiful fruit that it produces. But did you also know that it’s one of the leading causes of Las Vegas allergies? Mulberry shrubs bloom in the spring, and they are actually the #1 allergen in Las Vegas and the surrounding area. They are most prevalent in the southern part of the city and the oldest neighborhoods.

European Olive

Another top allergen in Las Vegas is the European olive tree. Like mulberry, planting of the European olive tree was banned in 1991, when the rate of allergies soared to unprecedented heights. This tree is native to the Mediterranean region, which means that it thrives in the sunny, arid, and mild Southwestern climate. But it’s also a major pollen producer, and its pores spread quickly on the wind.


Despite what you might think, you’re not likely to start coughing and sneezing if you walk into fluffy cotton clusters falling from this tree. Instead, the worst offender in cottonwood trees is their tiny particles of pollen, which are nearly invisible to the naked eye. Cottonwood trees produce the most pollen from March through May.

Now that you know what the most common allergens are in Las Vegas, you might be able to narrow your allergens based on the time of year and the plants in your yard. But to get the most accurate diagnosis, you’re better off going to the doctor. Fortunately, you can make an appointment with the best allergist in Las Vegas at Tottori Allergy & Asthma Associates.
