Residents in Livermore might want to double-check their backyards for standing water this week. The Alameda County Mosquito Abatement District has discovered a new invasive mosquito species, Aedes aegypti, known as a daytime biter and a carrier of serious diseases. These mosquitoes, spotted in areas west of Brookmeadow Park, between N. Mines Rd and East Ave, are a cause for immediate action due to their potential to spread illnesses like dengue, Zika, chikungunya, and yellow fever.

The district is taking this situation seriously, with staff scheduled to scour the neighborhood for breeding grounds today. According to a social media post by the Alameda County Mosquito Abatement District, residents can expect to see uniformed workers and white trucks marked with the ACMAD emblem on the prowl for stagnant water where these pests could multiply. People in the area should remain vigilant, look over their properties for any water collection, and eliminate it to prevent these pests from settling in.

The district has emphasized the urgency in dealing with these mosquitoes due to the health risks and their aggressive nature. "Responding quickly and thoroughly is critical for the district to eliminate Aedes aegypti," notes the ACMAD statement. The community's cooperation is essential, and those experiencing unusual mosquito activity, specifically during the day, are urged to contact ACMAD at 510-783-7744 or to visit their website for assistance and more information.
