Las Vegas looks dry and inhospitable, but the desert is alive. Pests adapt fast to heat spikes, rare downpours, and the web of irrigation lines that keep yards green. If you live here long enough, you learn that scorpions come up through weep holes when the ground cools, ants surge after monsoon rains, and roof rats treat oleanders like freeways. A good pest plan respects the rhythm of the Mojave, not just a generic national checklist.
What follows is a practical, month‑by‑month strategy anchored in how pests actually behave in the Las Vegas Valley. It leans on habit change, building maintenance, and targeted treatments. Chemicals have their place, but the best results come from pressure‑reducing tactics that make your property less worth their effort.
Most Las Vegas neighborhoods share three traits: block walls, rock or artificial turf landscaping, and drip irrigation. That combination changes microhabitats. Block walls create cool voids for scorpions and roaches, rocks hold radiant heat that attracts ants at dusk, and drip lines turn tree wells into oases. Add pool splash and air‑conditioning condensate, and you have water, warmth, and harborage where the open desert offers none.

Common household pests here include Argentine and rover ants, German and Turkestan cockroaches, house mice and roof rats, bark scorpions, wolf and cellar spiders, clover mites, and the occasional earwig bloom. Termites exist, though they tend to be subterranean species that follow moisture. Mosquito pressure swings with monsoon rain and backyard water features. Each pest peaks at different times, so the plan and timing matter.
A year‑round program rests on three pillars. First, cut off food, water, and shelter that you control. Second, fortify the structure so pests have to work to get inside. Third, time exterior treatments to the seasonal cycles that drive activity in the valley. When all three are in place, you stop large infestations before they start and handle the outliers with precision.
I have seen homeowners spray only when they see ants on the counter, then wonder why they return every three weeks in summer. Those ants are often trailing back to colonies in the soil under a palm or a block wall footing. Breaking that cycle means baiting when ants forage heavily, then following up with a non‑repellent barrier at the foundation and a granule in rock beds. Done with the right timing, you might treat less often overall yet keep ants quiet for months. Reaction alone rarely buys that stability.
By March, night temperatures lift and insects start moving. This is the best time to fix entry points and set the baseline for the year.
Start with the structure. Most Las Vegas houses have weep holes in the bottom brick or stucco vents by design. Those should never be sealed tight, but you can insert stainless steel mesh to keep scorpions and roaches from using them as doors while still allowing drainage. Caulk hairline gaps around window frames, stucco cracks, and utility penetrations. On newer builds, foam overspray around conduit often shrinks, leaving pencil‑sized openings ideal for ants and spiders. A half tube of exterior‑grade sealant can make a noticeable difference.
Weatherstripping on doors hardens under intense sun. Check for light bleeding under the front and garage access doors. A rodent can compress through a gap the width of your little finger, and a scorpion can flatten astonishingly. Install door sweeps with a brush or rubber seal and align the threshold. In block walls, look for eroded mortar joints near the soil line and fill them. Where the stucco meets the slab, replace missing backer rod so caulk can flex with seasonal expansion.
Landscaping often decides whether pests camp against your home. Trees touching the roof give roof rats a bridge. Trim branches back at least three feet from roof edges. Raise the canopy so the lowest limbs sit off the ground and reduce dense contact points with block walls. Replace thick mulch against the foundation with a 12 to 18 inch strip of bare concrete or rock so you can monitor and so ants do not nest under constant moisture. Drip emitters should wet soil at the tree’s drip line, not the stucco. Adjust clogged emitters instead of turning up the timer and flooding beds.
On water, two sources are underestimated. First, air conditioning condensate drains can discharge right at the foundation. Route the tubing so it drains into gravel away from walls or into a buried dry well. Second, backflow preventers, hose bibs, and irrigation manifolds often weep. A slow leak off a manifold can support thousands of ants invisibly under rock. Replace cracked gaskets and wrap threads with tape where appropriate.
On the pest control side, spring is when to establish a non‑repellent perimeter treatment should you choose to use pesticides. Non‑repellent insecticides allow ants and roaches to cross the barrier and carry active ingredient back to the colony, unlike repellents that only push them elsewhere. Apply a band around the foundation and along expansion joints, and treat the stem wall in the garage where storage often hides activity. In rock beds with a history of ant mounds, a broadcast of a labeled granular bait can set you up for a quieter summer. For scorpions, dusting cinder block wall voids and attic access points with a silica or diatomaceous earth product creates a dry barrier that remains when liquids break down.
Inside, focus on kitchens and baths. Pull the stove, clean the food spill strip that never gets attention, and vacuum behind the refrigerator grille where crumbs and grease collect. Under sinks, fix loose P‑traps and seal around pipes with escutcheon plates or foam. In multi‑unit buildings, roaches travel pipe chases. If you see shed skins or pepper‑like droppings in cabinet corners, place gel bait in out‑of‑sight cracks and use sticky monitors to gauge movement before you spray. Bait does more to collapse a roach population than a general aerosol, which can scatter them into adjacent units.
The stretch from June through September brings triple‑digit highs, rare but intense thunderstorms, and nightly spikes in activity. Heat drives pests into irrigation zones and shaded cracks, then sudden moisture flips foragers into high gear. This is when consistency pays off.
Ants are the headliners. Argentine ants expand fast along drip lines, especially in yards with lots of potted plants. If you see a trail across the patio, trace it to the source. Often a pot saucer filled after a monsoon shower becomes an ant refueling station. Dump standing water, elevate pots on feet, and move them off the stucco. When treating, place protein and carbohydrate baits along trails as close to nests as possible. Do not spray over baits. If you use a liquid perimeter, give it a day or two before baiting so the foraging pattern normalizes, then lay bait along those routes. Two small placements done well beat a dozen random drops.
Scorpions and spiders come up after sundown. Bark scorpions favor block walls and palm crowns. They follow the walls like highways and slip through gaps at electrical outlets and expansion joints. I have had success with a simple protocol: blacklight hunting in June to knock down adults on the exterior wall lines, sealing weep holes, and maintaining a dust band in the hollow blocks. Inside, glue traps behind furniture along baseboards show you whether you still have an entry point. If the traps stay empty for two weeks in July, your sealing likely worked.
Cockroaches in Las Vegas split into two main groups. German roaches live indoors, tied to kitchens and bathrooms. Turkestan roaches, often mistaken for American roaches, live outdoors in valve boxes, water meter boxes, and under landscape rocks. In summer, Turkestans will flood garages and patios at dusk. You can lower pressure by treating valve boxes with a labeled granule or dust, securing the covers, and reducing light. Switch bright white bulbs at entry doors to warm LEDs. Roaches are less attracted to the spectrum, and you will bring fewer into the house at night.
Mosquitoes depend on micro‑water. Pool covers that puddle after rain, clogged scuppers, and landscape drains with silt can breed enough larvae to supply the dispatchpestcontrol.com emergency pest control las vegas whole block. Inspect those areas after each storm. If you keep a fountain, add a mosquito dunk according to label directions and keep the pump running. Water features become neighborhood magnets otherwise.
Rats and mice hit their stride when fruit ripens and landscaping thickens. Even in desert areas, ornamental citrus and oleanders support roof rats. You will see greased rub marks on block walls and droppings on top of the wall cap if they are commuting. Thin the vegetation, pick up fallen fruit within 24 hours, and repair gnawed weep screeds at the garage. Set exterior snap traps in bait stations along wall runs rather than loose bait. In summer heat, anticoagulant baits can desiccate rodents in inaccessible attic voids and cause odor issues, a problem no one wants when the air is still.
Plan a light exterior treatment roughly every 6 to 8 weeks in summer if you live near vacant lots or golf course edges where pest loads run high. Where pressure is lower, you may stretch to 10 weeks. Always target soil interfaces, wall bases, and junctions rather than blanket spray. A precise approach reduces resistance and preserves beneficial predators that keep mites and smaller pests in check.
By October, nights cool and pests look for warmth. This is the time to tighten the envelope. Inspect the garage thoroughly. Door seals get brittle and mice exploit that. Shine a light from inside at dusk with the garage closed, and look for light at the corners. Adjust tracks and add side seals if needed. If you store dog food in the garage, transfer it to a lidded metal can. The smallest spill becomes a long‑term attractant.
In the attic, look for droppings, tunneled insulation, and displaced batts. Roof rats prefer elevated routes and will nest above the garage or in soffits. If you find runways, set traps on the routes and block entry at roof penetrations once you stop traffic. It pays to hire a company to do a one‑time exclusion if climbing pitches makes you nervous. In block construction, examine the joint where the roof meets the wall for gaps. A strip of hardware cloth and sealant can close a highway.
Landscape maintenance matters again. Bermuda lawns go dormant, and many homeowners reduce irrigation. That shift changes where pests live. Move firewood or stacked materials off the ground and away from walls. Vacuum window tracks to remove accumulated debris that holds moisture. Clean gutters, even in areas with only a few trees, because storm silt can form persistent wet pockets that draw insects.
A fall perimeter treatment can be lighter than summer in most neighborhoods. Focus on long‑lived products at door thresholds and entry points. Dust attic access openings lightly and keep glue boards in the garage where you can read the seasonal arc on what is moving. If you struggled with scorpions in summer, consider replacing old garage door weatherstripping now, not in spring, so you start winter tight. Replace or install self‑closing hinges on entry doors from garage to house to limit accidental open periods on cool evenings.
For recurring ant issues, swap to a different bait matrix in fall. Colonies cycle their preferences. If they took sweet baits in July, they may prefer protein or fat in October. I keep two brands with distinct active ingredients and rotate them to prevent bait shyness.
From December to February, visible activity drops. That makes it the best season for detail work that is harder to prioritize when everything is moving. Start with plumbing. Under sinks, repair any drip. A slow drip you ignore in summer supports silverfish and German roaches in winter when exterior sources dry. Bathroom fans accumulate lint and moisture film that attract small flies if the vent cap leaks; check the roof cap and reseal if needed.
Walk the perimeter on a sunny morning and look for tiny reddish mites crawling on south‑facing walls. Clover mites show up on warm winter days after rains. They do not bite, but they stain and alarm. A simple fix is to maintain that plant‑free strip against the stucco and avoid overwatering the adjacent beds. If you see dozens, a soap‑based wash and a low‑impact perimeter treatment can take the edge off.
Inside, pull out couches and move beds to vacuum along baseboards, especially in rooms with carpeting. Spiders set up in undisturbed corners. Use a crevice tool to remove egg sacs. Replace cardboard storage in closets with sealed bins. Cardboard wicks moisture and draws insects. If you have an older home with crawl space vents, inspect vent screens. A quarter‑inch hardware cloth keeps mice out more reliably than expanded metal with corroded spots.
Winter is also the safe season to address attic sanitation if rodents were present in fall. Removing contaminated insulation, sealing entry holes, and reinstalling insulation sets the stage for a cleaner spring. Many homeowners in the valley live with attic odors they chalk up to heat. Often the root cause is old rodent waste. Fix it now when temperatures are manageable.
For those who prefer a year‑round service, winter treatments can be less frequent, focusing on interior inspections and spot work rather than broad exterior sprays. A technician who opens a few valve boxes, checks glue boards, and inspects door sweeps gives you more value than someone who sprays the same band regardless of season.
A calendar works if it flexes with weather. In dry winters, you may go two months with little activity. In wet monsoon years, you might need two extra ant visits. Rather than a rigid schedule, anchor to seasonal tasks, then set reminders for checks that catch surprises early.
This set of touchpoints keeps you ahead without turning pest control into a second job. If a monsoon in July dumps an inch in an hour, add a mid‑month yard sweep to dump standing water and reset ant baits. If a construction project starts next door, expect displaced pests and consider an extra perimeter treatment that month.
Not every product behaves the same in 115 degree heat. Choose materials that tolerate UV and temperature swings. For sealing, use a high‑quality polyurethane or hybrid sealant on exterior stucco. It adheres better and flexes with heat than standard acrylic caulk. For mesh, stainless steel wool or copper mesh holds up where regular steel rusts and stains stucco.
When dusting block walls, use a hand duster with a long nozzle so you can puff a small amount into each void at the bottom course. Over‑applying dust clumps in our low humidity and loses effectiveness. For baits, store them inside at room temperature between uses. Heat‑stressed baits dry out fast and lose attractiveness. Replace bait placements if they crust.
On sprays, non‑repellent concentrates with long residuals perform well on shaded sides, but direct sun on the west wall can degrade them faster. Target shaded cracks and joints rather than open wall faces. If you want to reduce chemical use, stick to spot treatments and baiting plus diligent exclusion. In many neighborhoods, that combination keeps indoor pests to near zero.
A good local technician reads your property in five minutes. They will ask about irrigation timing, look at the block wall’s base, peer into a valve box, and check door sweeps before they pull out a sprayer. If your provider sprays without asking questions, you are buying a commodity, not expertise.
Call in help when you see any of the following: persistent scorpion sightings inside after you have sealed obvious entry points, German roaches in multiple rooms, roof rat noise in the attic, or termite tubes climbing the stem wall. Termites in Las Vegas usually require trenching and treatment with termiticide around the foundation. That is not a DIY project for most homeowners. Similarly, serious rodent infestations pay for a professional exclusion job. The upfront cost often ends up lower than months of trapping and patching.
Work with your pro on an integrated plan. Ask for a seasonal schedule that includes exclusion and monitoring, not just chemical service. Make sure they rotate bait actives for ants and roaches and that they log what and where they applied. If you prefer reduced‑risk approaches, discuss botanical oils and mechanical controls. They have limits, but used well, they help.
Every home is a bit different. Pools add moisture and lights. Night swimmers carry insects into the house on towels. Keep a covered hamper in the garage for wet textiles and rinse decking lights with a warmer spectrum. For rental properties, set a quarterly interior inspection in the lease. Many infestations grow because no one opens the cabinet under the guest bath sink for a year. Include language that prohibits storing food in garages outside sealed containers.
Homes near the desert fringe or washes absorb more wildlife. Bark scorpions drift after heavy winds and stack up along walls. In these zones, invest in fine mesh on weep holes and gaps, maintain a 24 inch crushed rock barrier around the foundation, and consider monthly blacklight checks in peak season. For rodent‑prone areas, metal flashing along the bottom course of block wall facing the wash adds a climb challenge that reduces nightly roof traffic.
Pest control is detective work. Glue boards tell stories. Place them in the garage near the water heater, in the pantry under the lowest shelf, and behind a couch against an exterior wall. Check monthly. A few ants in June, then none, means your exterior work is holding. A sudden run of small dark beetles might point you to old bird seed. A scorpion or two every July inside the garage suggests the door seal is aging or the block wall dust needs refreshing.
Valve boxes and irrigation manifolds are also honest. Pop the lids every other month. If you see roach casings, treat inside the box and adjust your water schedule to avoid constant saturation. If you find earwigs piling up, cut back mulch and allow the surface to dry between watering. Earwigs boom after rains and in constantly damp beds; a simple timer adjustment often collapses the population.
The kitchen remains the bellwether. Any new activity usually shows up there first. Keep counters dry at night, wipe up sweet spills immediately, and run the disposal with a strong flush. Cover pet food after breakfast, not all day. Those small habits starve opportunists and make your bait stations more attractive if you need them.
A well‑maintained Las Vegas home can stay largely pest‑free on a modest budget of time and money. Expect to invest a weekend in spring for sealing and cleaning, a few evenings in summer for monitoring and quick fixes after storms, and an afternoon in fall to tighten the envelope. Professional service, if you choose it, ranges by company and home size, but many homeowners see the best value in a bi‑monthly exterior program with on‑demand interior visits during summer peaks. If your yard borders open space or you have heavy landscaping, monthly in summer is reasonable.
Measured over a year, prevention jobs like trimming vegetation, fixing leaks, and managing storage do more than repeated sprays. You will also notice side benefits: lower water bills from repaired irrigation, fewer allergy triggers from cleaner vents, and a garage that does not smell like something died every August.
Las Vegas rewards consistency. If you act before pests surge, you rarely face the grim cleanouts. Treat the structure like a living system that responds to heat, water, and time. Seal in spring, monitor and adjust in summer, fortify in fall, and tune the interior in winter. Use chemicals when they do the most good, not as a reflex. The desert will still teem around you, but your home can feel like the quiet center it should be.
