San Antonio has seen a prolonged period of above-average temperatures this winter, resulting in an unusual warmth that’s affecting not only drought conditions but also bugs. Experts warn that the warmer weather will lead to a significant “pest surge” this spring.
The top U.S. cities on the Pest Index include San Antonio, Boston, Cleveland, Washington D.C., Louisville, Florida, New Orleans, Denver, Salt Lake City, and Seattle. These cities are expected to experience an increase in bites, infestations, and health issues related to pests over the coming months.
Warmer temperatures extend the activity of pests like mosquitoes, ticks, and other insects, allowing them to breed more and increasing the risk of infestation. Mild winter temperatures also prevent insects from dying off, leading to an earlier start of pest activity in the spring. Additionally, warm and humid conditions are perfect for breeding, with mosquito eggs hatching faster and developing quicker in warmer temperatures.
On the other hand, cooler winter months cause many pests to become dormant or hibernate, but brief warm spells can disrupt this, allowing them to remain active longer. If the winter is unusually cold, pests may seek shelter indoors, leading to potential infestations inside homes and businesses.
The weather in San Antonio plays a critical role in pest behavior, with warmer temperatures and moisture allowing pests to survive longer and breed more efficiently. As a result, residents can expect to face more frequent infestions, bites, and pest-related health issues as the season progresses.
