Why are Mosquitoes Still Biting in San Gabriel?

The continued mosquito pressure in San Gabriel can create frustration for residents despite the summer season coming to an end. The stretches of high heat, rainfall, and humidity contribute to additional areas where mosquitoes can rest and breed, and can encourage their spread and growth due to the lack of dropping temperatures. While an end date isn’t guaranteed, it’s important for residents to continue working with San Gabriel mosquito control professionals to address their growing presence.

What Keeps Mosquito Populations Going

Mosquito activity in San Gabriel can be affected by a number of factors. For one, weather patterns can intensify mosquito activity when rain and high humidity create conditions for breeding. Residential areas commonly include gardens, beautifully watered lawns, and drainage systems that allow mosquitoes to rest within these microclimates. Container mosquitoes can become an increasing issue in these areas as mosquitoes lay eggs within only one teaspoon of water. This can lead to overlooked breeding sites found within children’s toys, trash bin lids, or tarps after rainfall.

Fall Breeding Spots Homeowners Often Miss

While mosquitoes are known to be found in areas of standing water or local parks, they can easily be found within San Gabriel neighborhoods as well. Two commonly overlooked areas are downspouts and gutters. These can become clogged with leaf litter or brush which reduces proper drainage and allows water to collect unnoticed. Poor drainage can also lead to areas where uneven pavement or low-lying areas collect standing water and invite mosquito breeding. Small containers can include children’s playsets, bird baths, overturned buckets, or other outdoor decor that can collect water after rainfall or daily watering.

Steps to Reduce Mosquito Pressure Around the Yard

Despite growing mosquito pressure, there are steps you can take to reduce mosquito activity at your home in San Gabriel. To address this, it’s important to recognize the conditions that attract mosquito nesting and breeding. Reduce standing water within clogged gutters, downspouts, or areas where leaky irrigation or pipes create areas for breeding. Dump standing water from bird baths, planter saucers, tarps, or other areas where water can collect after rainfall. Trim areas of dense vegetation or brush, and reduce the amount of leaf litter that collects around the yard or underneath the deck. For outdoor activity, use EPA-registered mosquito repellents and long clothing when the temperature permits. Additionally, consider using fans or mosquito repellent products, such as citronella candles, when spending time outdoors during dusk and dawn.

What Professional Mosquito Control Can Add

Professional mosquito control is a helpful way to reduce and control mosquito activity at your San Gabriel home. Our team at Mosquito Squad of Pasadena begins each plan with a thorough property inspection to learn the layout, inspect areas of mosquito activity, and note areas of concern. This allows us to help create a tailored plan that suits your home and needs.

Our traditional mosquito control plan, Barrier Treatment Plus, is designed to reduce and control mosquito activity for up to 21 days at a time. Our team will use this potent insecticide to target areas where mosquito resting and breeding are likely in order to repel mosquito activity. Not only that, but this blend binds to the surface to create a barrier of defense that disrupts the cycle of breeding and withstands regular rainfall. While we offer one-time sprays for events or gatherings in San Gabriel, this plan is best run on a recurring basis to ensure the most effective barrier for mosquito control.
