Mosquitoes are still a major problem in Los Angeles in the fall. Warm autumn temperatures keep mosquitoes active long after they have stopped in other parts of the country.
You might be hoping cooler temperatures will bring relief from the mosquitoes. But in Los Angeles, that hope is unfortunately not well-founded. Mosquitoes are still active here as late as November.
The main reason mosquitoes stay active so long here is temperature. Mosquito activity slows down when sustained temperatures fall into the fifties. In LA, this rarely happens before late in the year. October tends to be warm, and Santa Ana conditions can push temperatures well up even in the middle of the autumn.
It doesn’t help that mosquitoes in the fall had all summer to breed. They’re often at their peak in numbers by September. So there are simply more of them around in the first place.
West Nile virus continues to be an issue late in the year. In fact, you’re likeliest to catch it between August and November in Los Angeles. The virus circulates between mosquitoes and birds and a greater proportion of mosquitoes is able to infect you toward the end of the year.
To keep mosquito problems in check late season, check for standing water sources weekly. Dump them if you find them and scrub the containers so eggs don’t stick to the side. And if you are working with a professional for treatment of mosquitoes, keep doing so until the mosquitoes truly slow down.
