Why Massive Rain Events Create Explosive Mosquito Populations

How Rain Affects Mosquito Activity in Houston, TX

The flat terrain and subtropical climate in Houston create the perfect storm for mosquito breeding and hatching. Low-lying areas around the metro flood easily after a heavy rainfall, and the high humidity increases the ability of eggs to hatch into biting adults in as little as 7 days. Floodwater species in Houston lay drought-resistant eggs which are able to withstand long periods without rainfall. Once rainfall occurs, those drought-resistant mosquito eggs can hatch within just a few hours.

This combination of humidity, rainfall, and multitude of areas that accumulate flood water all lead to high explosions of mosquito activity within 1-2 weeks after heavy rainfall. In order to mitigate these risks, it’s important to take action at your home to limit their ability to nest and breed.

If the mosquito population at your home feels overwhelming to address on your own, our team at Mosquito Squad of Houston is ready to help. We offer multiple outdoor treatment options to address mosquitoes and over 20 common pests you may experience.

How Professional Mosquito Control in Houston Can Help

There are a couple common DIY options that Houston residents can try. Citronella candles help to deter mosquitoes with a blend of scents such as lemongrass or bergamot. Unfortunately, this option is highly dependent on location, range, and the velocity of the wind. Mosquito dunks are helpful in areas where deep standing water tends to accumulate. This can be outdoor buckets, bird baths, or artificial ponds.

Ensure that your grass is trimmed to limit daytime resting areas, and trim the perimeter of your yard to limit movement from neighboring areas of dense vegetation. Dump standing water shortly after rainfall. Mosquitoes only need one bottle cap worth of water to lay their eggs, which means bird baths, clogged gutters, and children’s toys all create the perfect breeding grounds.

Lastly, consider hiring a professional mosquito control service. This option helps to not only reduce the mosquito population, but also helps to control their ability to nest and breed. By scheduling a treatment before an oncoming storm surge, or immediately after, you can get ahead of the coming mosquito hatching cycle.
