Arizona Pest Control Calendar at a Glance

Arizona pests change with the weather, but pest activity never fully stops. This quick calendar shows common Arizona pests by season.

For example, a Gilbert homeowner may notice ants in the kitchen during a dry spell, then see mosquitoes and flies increase after a monsoon storm.

Why Arizona Has Pest Problems All Year

Arizona has pest problems all year because warm temperatures, mild winters, and sudden moisture create steady pest pressure. Some pests slow down in cooler months, but many survive indoors.

In Gilbert and nearby Greater Phoenix communities, desert landscaping, block walls, irrigation, pet bowls, garages, and shaded patios can all attract pests. Home pests include ants, scorpions, spiders, termites, and rodents. Meanwhile, commercial properties may deal with roaches, flies, ants, rodents, and stinging insects.

Spring Pests in Arizona

Spring pests in Arizona often include ants, bees, wasps, termites, and spiders. As temperatures rise, pests become more active, start nesting, and search for food and water.

Ants may trail into kitchens, bathrooms, break rooms, and patios. Bees and wasps may build nests under eaves, in sheds, or around outdoor seating areas. Termites may become more noticeable if you see mud tubes, discarded wings, or damaged wood.

Spiders also become easier to spot as insects become more active. Since spiders follow food sources, a growing insect problem can lead to more webs in garages and storage areas.

Spring checklist:

• Seal cracks around doors, windows, and utility lines
• Trim plants away from the building
• Remove yard debris
• Watch for nests and termite signs
  

Summer Pests in Arizona

Summer is one of the most active pest seasons in Arizona because extreme heat pushes pests toward shade, water, and indoor spaces. In Gilbert, this often means more scorpions, cockroaches, ants, crickets, spiders, and bed bug concerns.

Scorpions may hide in garages, block walls, bathrooms, closets, shoes, and shaded patios. Cockroaches gather near drains, trash areas, kitchens, and bathrooms. Ants may enter homes and businesses looking for water during long dry stretches.

Crickets can become a problem around exterior lights, garages, and landscaping. They may attract scorpions, so reducing cricket activity can help lower scorpion pressure. Bed bugs can appear any time of year, but summer travel can increase risk.

Example: If you see crickets in the garage and later find a scorpion near a bathroom, both issues may be connected.

Monsoon Season Pests in Arizona

Monsoon season can make pest problems worse because moisture creates breeding sites and changes pest movement. Mosquitoes, termites, ants, cockroaches, and flies often become more noticeable after rain.

Mosquitoes can breed in small amounts of standing water, including buckets, plant saucers, clogged drains, and low spots in the yard. Flies may gather around trash cans, dumpsters, drains, and wet organic material. Roaches may enter through gaps around doors or plumbing.

Termites and ants can also become easier to spot after moisture. If you see termite swarmers, mud tubes, or recurring ant trails after storms, do not ignore them.

Monsoon checklist:

• Empty standing water weekly
• Clean trash bins and dumpster areas
• Check door sweeps
• Keep landscaping trimmed
  

Fall and Winter Pests in Arizona

Fall and winter pests in Arizona often move indoors for shelter, warmth, food, and water. Even when outdoor activity slows, rodents, roaches, spiders, scorpions, and bed bugs can still affect homes and businesses.

In the fall, rodents may enter through small gaps near garages, roofs, plumbing lines, and utility openings. Spiders may become more visible in corners and storage rooms. Roaches may stay active near kitchens, drains, bathrooms, and break rooms.

Winter in Gilbert is mild, so pests do not always disappear. A homeowner may hear scratching in the attic, find droppings in a pantry, or see roaches near a sink.

Fall and winter checklist:

• Replace worn door sweeps
• Seal gaps around pipes and utility lines
• Store food and pet food in sealed containers
• Reduce garage clutter
• Inspect holiday boxes
