Heavy rain across the greater Houston area in recent weeks has created ideal breeding conditions and led to a record surge of mosquitoes. Fort Bend County officials have declared a public health emergency in response and are preparing for aerial spraying.

Houston Methodist experts are urging residents to take precautions to reduce their risk of mosquito-borne illnesses like West Nile virus.

BEST WAYS TO PREVENT MOSQUITOES AT HOME

• Eliminate standing water at your house: Mosquitoes lay eggs in even small amounts of water found in planters, toys, gutters and outdoor furniture.
• Use effective repellents: Products with DEET, picaridin, or oil of lemon eucalyptus offer the most reliable protection.
• Skip ineffective solutions: Citronella candles and bug zappers provide little meaningful protection against bites.
• Wear protective clothing: long sleeves, pants and permethrin-treated clothing can add an extra layer of defense.

“Not all mosquito repellents are created equal,” said Dr. Olivia Tomasco, primary care physician at Houston Methodist West Hospital. “Science-backed ingredients like DEET or picaridin are your best option, especially when mosquito activity is high like we’re seeing right now.”

KNOW THE HEALTH RISKS

While most mosquito bites are harmless, some can transmit serious illnesses.

West Nile virus is the most common mosquito-borne disease in the United States and can lead to severe complications particularly in people who are immunocompromised or over 60 years old. Signs to watch for include fever, headache and rash. Anyone experiencing concerning symptoms after a mosquito bite should seek medical care, experts advise.

HEIGHTENED VIGILANCE DURING SURGE

With mosquito populations at unusually high levels this season, Houston Methodist physicians say residents should be especially cautious when spending time outdoors, particularly at dawn and dusk when mosquitoes are most active.

“Eliminating mosquito breeding grounds and using effective repellents can dramatically reduce your risk,” Tomasco said. “Taking these simple steps can help keep you and your family safe, even during a surge like this.”
