What Time of Year Are Pests Worst in Farmington, NM?

June 8, 2026

Pest activity in Farmington does not follow a single predictable pattern. Different pests peak at different times of year, and the region’s extreme temperature swings—from below-freezing winter nights to summer highs above 95 degrees—mean that something is always active. Homeowners who understand the seasonal cycle can plan ahead and avoid being caught off guard. Pest control services in Farmington are designed around these local patterns to keep homes protected throughout the year.

Spring: The Wake-Up Period

As temperatures rise in March and April, overwintering insects begin to emerge. Ants become active early in the season and start establishing foraging trails. Spiders that sheltered indoors during winter become more visible. Wasp queens that survived the cold begin building new nests around eaves, fences, and outbuildings. Spring is also when termite swarmers may appear, which is a sign of an established colony nearby. Early spring treatments are critical for knocking back pest populations before they build momentum heading into summer.

Summer: Peak Activity

Summer is the most intense period for pest activity in Farmington. Scorpions are at their most active from June through August, frequently turning up inside homes during nighttime hours. Cockroach populations grow rapidly in the heat, especially in kitchens and bathrooms where moisture is available. Ant infestations tend to intensify as colonies expand and send more foragers indoors searching for water. Wasps and hornets are also at peak numbers and can become aggressive near nests. Centipedes, fleas, and ticks round out the list of warm-weather pests that affect local homes.

Fall: The Migration Indoors

Fall is when many pests begin transitioning from outdoor habitats to indoor shelter. Mice and pack rats start seeking entry points as nighttime temperatures drop, and by October, rodent activity inside homes picks up noticeably. Spiders also move indoors during this period. Box elder bugs and other occasional invaders may cluster on south-facing walls looking for warmth. Treating the exterior perimeter of the home in early fall is one of the most effective steps homeowners can take to prevent a winter infestation.

Winter: Rodents and Indoor Pests

Cold weather does not eliminate pest problems in Farmington – it changes them. Outdoor insect activity slows, but any pests that made it indoors during fall will remain active throughout the winter. Rodents are the primary concern during this season. Mice and rats that established themselves inside walls, attics, or crawl spaces will continue to feed and breed all winter long. Cockroaches and spiders that found their way inside also persist. Learn more about rodent warning signs in our post on how the desert climate affects rodent behavior.

Year-Round Protection Is the Most Effective Approach

Because pest pressures shift throughout the year rather than disappearing entirely, quarterly or bi-monthly treatments are the most reliable way to stay protected. Each seasonal visit addresses the pests most likely to be active at that time while reinforcing the barrier around your home.

 Trustindex verifies that the original source of the review is Google. Larry’s Pest Patrol did an excellent job treating our townhouse for termites.  From the beginning, their communication and attention to detail were impressive.  Brian, the owner, called me the day before the scheduled treatment to make sure I was prepared and that everything was ready for the work to begin the following morning. Brian and Jay arrived on time on the day of treatment.  Before starting, Brian took the time to answer my questions and listen carefully to my concerns, particularly about the gravel path on the east side of the townhouse.  That path has both large and small gravel arranged in a specific way, and I wanted to make sure the treatment work did not disturb that arrangement. Brian and Jay were very accommodating.  They laid down plastic that I provided so the larger gravel could be kept separate from the smaller gravel while the work was being performed.  Jay dug the necessary trenches around the townhouse for the termiticide treatment and then took the extra time to return the gravel to its original arrangement when the work was complete. Matt, the service manager, also did an excellent job foaming the wall cavities.  He was very careful about where he made the necessary access holes in the drywall, choosing inconspicuous locations whenever possible.  After the foaming was completed, Matt went back and filled the holes he had made, leaving the work neat and unobtrusive. Brian did an equally good job where drilling into concrete was required.  He selected inconspicuous locations for the holes, pumped the termiticide into the drilled areas, and then went back afterward and filled the holes with cement so the finished work was clean and professional. Brian, Jay, and Matt worked very well together as a team.  They were professional, respectful of the property, careful with the details, and completed the job in a timely manner.  I was very pleased with both the quality of their work and the way they treated my property throughout the process. I would not hesitate to recommend Larry’s Pest Patrol to anyone needing professional termite treatment.

 Trustindex verifies that the original source of the review is Google. I had a technician come out to my Dads house that hasn’t been treated since the 60’s! Daniel did an amazing job and went above and beyond to treat all of the critters there. He set bait traps, sprayed around the property both inside and out. He went thru the entire outside of the house and got rid of 50 years of cobwebs. The entire house looked amazing when he was done! I couldn’t be happier with the service from Larry’ pest control. Highly recommend! Ask for Daniel!

 Trustindex verifies that the original source of the review is Google. James was my pest technician today. He was prompt, friendly and knowledgeable. He made sure to address my main concerns (ants) and got rid of webs and wasp nests on my house. I also wanted to mention that I have had a good experience with the office staff when I call. The lady that answers is always friendly and ready to help! I’m glad I switched pest companies because Larry’s Pest Control has been great thus far!
