Mosquitoes are attracted to increased moisture, shade, and the protection of trees, bushes, and shrubs. Common reasons we see for high mosquito activity is overwatering of grass and plants, thick bushes and overgrown plants, and any standing water on the property.
The surrounding environment also plays a very significant role in localized mosquito activity. Homes that back on to nature preserves, and/or are in close proximity to bodies of fresh water will no doubt be challenged by mosquitoes.
