Living in South El Monte is convenient, affordable, and close to everything you need. The San Gabriel Valley offers warm weather year-round, beautiful tree-lined neighborhoods, and a variety of outdoor spaces to enjoy. It’s your home.
But…then comes mosquito season. Suddenly, every evening activity becomes an annoyance. All because of the constant buzzing, biting, and swatting. And because of South El Monte’s warm temperatures and irrigation systems, they create the perfect mosquito habitat that doesn’t take a winter break. Irrigation runoff, decorative water features, and overwatered lawns all contribute to the perfect mosquito breeding conditions.
While most people brush mosquitoes off as an irritation to live with and nothing more, there’s another dangerous side to mosquitoes. While they are pure annoyances, they also carry real health risks. And in Southern California, those risks are alive and well year-round.
With every mosquito bite, you’re rolling the dice on whether that mosquito could result in something more serious than an itchy welt.
West Nile Virus: The Most Common in SoCal
West Nile virus is the most common mosquito-borne illness in Southern California, carried by Culex mosquitoes (the ones that bite at dusk and dawn). So, if you’re getting bitten during evening patio time or morning coffee hour, those are the ones you’re dealing with.
The majority of people infected with West Nile virus don’t show any symptoms. But 1 in 5 people will develop a fever, headache, joint pain, vomiting, diarrhea, or rash. With most severe cases (especially in children or the elderly), it can cause brain inflammation called encephalitis or meningitis. This is life-threatening.
And there’s no doubt it’s here. West Nile has been detected in mosquito samples throughout Los Angeles County, including the San Gabriel Valley.
Zika, Dengue, and Invasive Aedes Mosquitoes
While Zika virus and dengue are rare in California, there’s a distinct problem. Aedes mosquitoes (an aggressive, invasive breed of mosquito) can carry both of these viruses.
These mosquitoes breed in surprisingly small amounts of water (a bottle cap’s worth), and they bite and buzz all day long. Once they’re established, avoiding them is next to impossible.
As climate patterns shift and mosquito populations adapt to this, the risk of these viruses continues to increase. Being proactive and preventing mosquito populations from growing now means you’re not gambling with your health later.
Dog Heartworm
Even if your dog spends most of his time inside, he’s not safe from mosquitoes. All it takes is one mosquito bite for your dog to get heartworm.
Heartworm disease is caused by a parasitic worm spread through the bite of a mosquito. The worms mature, mate, and produce offspring while living inside your dog. And if left untreated, it can cause lung disease, heart failure, and other organ damage in pets.
Allergic Reactions
Some people are allergic to mosquitoes and develop large welts, significant swelling, and secondary infections. For children and elderly people, especially, what can start as a small bite can turn into a large medical problem.
