Drier and warmer winters generally affect pest populations by allowing more of them to survive the winter, leading to larger populations the following spring and summer.
Mild winter conditions, such as those the Valley is experiencing, can increase pest infestations. Warmer winters disrupt the natural life cycle of pests, causing them to become more active and reproduce earlier than usual.

Here are some key points about how warmer winters impact pest populations:
How warmer winters impact pest populations
Increased survival rate
With milder temperatures, more pests can survive the winter months without going into full dormancy, leading to larger populations in the spring.
Earlier emergence
Warmer weather can cause insects to emerge from hibernation earlier than usual, potentially leading to increased pest activity in the early spring.
Faster reproduction
Warmer temperatures can accelerate the reproduction rate of many pests, leading to more offspring in a shorter period.
Potential for new pest species
Warmer climates can allow invasive pest species to expand their geographic range.
Pests that might be particularly impacted by warmer winters
Even though Arizona winters are generally mild, some pests remain active during this time. Here are a few common warm-winter pests in Arizona:
Cockroaches: These resilient insects thrive in warm, humid conditions, making Arizona homes an attractive refuge during winter.
Termites: Termites are active year-round in Arizona thanks to the state’s mild climate.Subterranean termites, the most common type in the region, can cause significant damage to wooden structures.
Rodents: While primarily a year-round issue, rodents like mice and rats seek shelter and warmth in attics and other unused spaces during colder months.
Spiders: Some spider species are more active in winter, seeking warmer indoor environments.
This is not an exhaustive list, and other pests may also be active depending on specific weather conditions and local factors.
If you’re experiencing a pest problem in your Arizona home, it’s always best to consult with a professional pest control company for identification and effective treatment options.
