The answer to 'why is my mosquito swarms' is that mosquito infestations are typically caused by standing water near your home, which provides an ideal breeding ground for these pests. Mosquitoes lay their eggs in stagnant water, and the larvae hatch and develop into adult mosquitoes within just a few days. Common sources of standing water include clogged gutters, birdbaths, pet bowls, and even small puddles in your yard.
Symptoms of a mosquito infestation include an increased number of mosquitoes around your home, more mosquito bites on you and your family, and potentially an uptick in mosquito-borne illnesses like West Nile virus or Zika. To address a mosquito problem, you'll want to eliminate any sources of standing water, use insect repellent, and consider professional mosquito control services if the issue persists.
