Gilbert’s desert climate means pests never really take a break. Even though the heat here is brutal, different critters emerge or retreat through the year depending on temperature, rain, and where they can hide. If you’re like me, half the time you don’t know whether to treat scorpions, mosquitoes, roaches, or all of them. That’s why a seasonal pest control plan is so helpful.
This guide walks you through what to watch for each season and which DIY pest control products are especially useful in Gilbert, AZ. Use it to stay ahead or at least feel a little less surprised when something crawls in.
Understanding Seasonal Pest Cycles in Gilbert
Pest activity in Gilbert really follows the weather: when things heat up or cool down, bugs respond. Here’s a rough sketch:
- Winter (Dec- Feb) - mild but active: Gilbert doesn’t get very cold, and many pests stay active. Pests like rodents, spiders, and crickets stay active.
- Spring (March-May) - breeding season begins: warm temperatures wake up many pests like scorpions, ants, bees, termites, and mosquitoes.
- Summer (June- July) - peak pest activity: Gilbert summers are extremely hot, pushing pests indoors for moisture and shelter. Pests like flies, termites, and wasps.
- Monsoon (July-September) - moisture boosts pests: moisture boosts pests like flying ants, termite swarmers, and spiders due to flooding.
- Fall (Oct- Nov) - pest migration indoors: as the temperature falls, pests look for warm sites. Rodents, crickets, and spiders become active.
Common troublemakers here? Think scorpions, ants, roaches, mosquitoes, spiders, and rodents, all of them showing up in different ways at different times.
Spring: Time to Stop Pests Before They Multiply
Common Pests: Ants, termites, mosquitoes, spiders
In spring, things start to wake up. Ants build out their trails, termites swarm if their colonies are ready, and mosquitoes take advantage of any lingering water.
DIY Products to Use:
- Insect barrier sprays and granules treat foundation cracks, garden edges.
- Mosquito dunks drop these in any standing water (pots, drains) so larvae can’t survive.
- Sticky traps are helpful early on to catch small, sneaky insects before they explode in number.
Tips:
- Walk your foundation, check screens, and seal any cracks.
- Remove or empty any water sitting in gardening pots, saucers, or gutters.
- Keep an eye out for termite swarmers; if you see wings, maybe time for a professional check.
Summer: Peak Pest Activity and Heat Challenges
Common Pests: Scorpions, cockroaches, crickets, flies, mosquitoes
In Gilbert, monsoon rains can flood usual hiding spots, pushing scorpions indoors. Roaches love warm, damp corners, especially in A/C homes.
DIY Products to Use:
- Food-grade diatomaceous earth (DE) is ideal for dry areas where pests hide; it is non-toxic if used right.
- Scorpion-specific sprays or traps there are products made especially for scorpions, and traps help monitor activity.
- Outdoor bug zappers or yellow lights help reduce flying insects around your patio or yard.
Tips:
- Seal up pet food and water sources that attract roaches and ants.
- Don’t overwater your yard or plants. More water = more bugs.
- Inspect shoes, lawn furniture, and dark corners regularly. Scorpions especially find tiny, shady crevices to hide.
Fall: Prepare for Indoor Invaders
Common Pests: Spiders, silverfish, rodents, crickets
As nights cool, pests start creeping inside. They’re looking for warmth, water, and a place to settle in.
DIY Products to Use:
- Door sweeps and gap sealants don’t underestimate these. Even a small gap = pest entry.
- Rodent traps and repellents are helpful once rodents try to nest inside.
- Perimeter insect sprays are applied around baseboards and entry points.
Tips:
- Tidy up garages, attics, and storage areas; pests love clutter.
- Store firewood or building materials well away from the house.
- Check insulation and weather stripping around doors/windows to block entry.
Winter: Maintain Indoor Protection
Common Pests: Roaches, ants, spiders, pantry pests
Yes, winter in Gilbert doesn’t mean bug-free. Roaches and ants don’t fully disappear.
DIY Products to Use:
- Glue traps are great for monitoring insect activity inside.
- Roach baits/gel formulas can be very effective when hidden in the right spots.
- Natural essential oil repellents (like peppermint or citrus) are helpful in food-storage areas or closets, though not a total fix.
Tips:
- Check pantry shelves, kitchen cabinets, and under sinks regularly.
- Make sure drains and sinks are dry when not in heavy use, as water draws bugs.
- Even in cooler months, doing a monthly check of early signs helps a lot.
Difference Between Pest Control Needs in Each Season
Spring vs. Summer
Spring pests start small. Ants, termites, and mosquitoes begin nesting and hatching, so the problem is more about stopping things early. Barrier sprays, mosquito dunks, and sticky traps usually do the job because infestations haven’t fully taken hold yet. Prevention mostly comes down to sealing cracks and removing standing water.
Summer looks very different. Heat drives scorpions, roaches, and flies into full activity. These pests move fast and hide well, so the approach becomes more defensive. Food-grade diatomaceous earth, scorpion-specific sprays or traps, and even yellow outdoor lights make a bigger difference. Moisture control and protecting entry points matter far more in summer than in spring.
Summer vs. Fall
Where summer pests are active and out in the open, fall pests tend to move indoors. Spiders, rodents, and crickets look for warm places to settle. DIY solutions shift toward blocking entry, gap sealants, door sweeps, rodent traps, and perimeter sprays around skirting boards.
Unlike summer, fall pest control isn’t just about reducing activity outside but stopping pests from turning your home into their winter base.
Fall vs. Winter
Fall pests are mainly “invaders.” Winter pests are “stayers.” Roaches, ants, and pantry pests hang around inside because indoor conditions stay warm and predictable. You’re not dealing with sudden infestations as much as slow, persistent ones.
So, winter control becomes about monitoring and maintenance: glue traps, gel baits, and natural oil repellents. The focus shifts to inspecting pantries, keeping drains dry, and staying consistent with checks, even when it feels like pests have gone quiet.
Winter vs. Spring
Winter pests hide inside. Spring pests restart outdoors.
Glue traps and roach gels give way to barrier sprays, mosquito dunks, and fresh sealing of exterior cracks. It’s more about preventing the first wave before the summer spike hits.
Why Seasonal Pest Control Matters in Gilbert
