One of the most common questions we hear from homeowners in North Las Vegas is some version of: “Is this bee season?” The honest answer for Clark County is that there isn’t really an “off season” — Africanized bees in the Mojave Desert are active year-round. But there are distinct peaks and troughs that every homeowner in the area should know.
Why Las Vegas Has a Different Bee Calendar Than the Rest of the Country
In most of the United States, bee season runs April through September, with colonies going semi-dormant in winter. That model doesn’t apply in the Las Vegas Valley.
Clark County winters are mild — temperatures rarely drop below freezing for extended periods, and foraging weather (above 55F) is available for 10—12 months of the year. Africanized honey bee colonies don’t cluster in winter the way northern European honey bee colonies do. They remain active, continue foraging on warm winter days, and build population throughout the year.
The result: there is no month where bee activity fully stops in North Las Vegas. There are only months with lower activity and months with very high activity.
Month-by-Month Bee Activity in Clark County
January — February: Low but Present
Cooler temperatures reduce foraging and swarming activity. Established colonies maintain population but grow slowly. Swarm calls are rare but not unheard of — a warm week in February can trigger early swarm activity from large colonies that have been building through the fall. If you have a known colony on your property, this is the easiest time to schedule removal — smaller colony size, less defender population.
March — April: Primary Swarm Season Begins
This is when the first major wave hits. Winter colonies that have been building population start hitting the threshold that triggers swarming — the reproductive splitting of a large colony into two. Scout bees begin surveying residential areas for cavity spaces. Swarm clusters appear on trees, fences, and structures throughout NLV neighborhoods.
March and April are when we start seeing sharp increases in call volume. Desert-adjacent neighborhoods in 89085 and 89084 — where wild colonies in the desert fringe are abundant — see particularly high swarm pressure during this period.
What to do: Check your property for bee activity near walls and fences. If you’ve had a colony removed in a previous year, verify that the sealing work is intact. This is the highest-risk time for new colonization.
May: Peak Swarm Season
May is the busiest bee removal month of the year in North Las Vegas. Temperatures are warm but not yet extreme, foraging is optimal, and swarm activity is at its highest. Swarm clusters are common throughout the valley. Any exposed void space — weep screeds, open pipe penetrations, block fence hollows — is actively being scouted.
A swarm that lands on your property in May and isn’t addressed within 24—48 hours will likely move into a cavity and begin establishing. Once established, removal complexity and cost increase significantly.
June — August: Established Colony Season
Peak summer heat reduces swarming activity — extremely high temperatures are hard on bee colonies during swarming, and fewer new swarms are dispatched. However, the colonies that established in spring are now growing rapidly. A colony that moved into a wall in March is a large, established hive by July.
This is also when homeowners start noticing established colonies they didn’t know they had — the buzzing becomes audible through walls, honey staining appears on interior drywall, and bees start emerging from outlets or light fixtures as the comb mass grows.
Summer is also when emergency bee removal calls spike. Hot weather, outdoor activities, and landscaping near established colonies create more disturbance situations. An Africanized colony that has been quietly occupying a fence for several months becomes visible and dangerous when the mowing gets too close.
September — October: Secondary Swarm Season
A second, smaller wave of swarming activity typically occurs in September and October as temperatures drop from summer peaks back into comfortable foraging range. This secondary season is generally less intense than spring but still produces meaningful swarm and new-colony calls.
The secondary season is also when colonies that grew through summer are at maximum size — the largest defender populations of the year. Late-summer removal jobs tend to involve the largest, most challenging hive extractions.
November — December: Winding Down
Activity decreases as temperatures drop. Swarming largely stops. Established colonies enter a maintenance phase — foraging continues on warm days, population growth slows. Call volume drops. For homeowners who noticed bee activity over the summer and delayed calling, this is a reasonable window for scheduling removal on an established colony before the next spring peak.
Swarm Season in Desert-Adjacent Neighborhoods
If you live in Valley Vista, Deer Springs, or other neighborhoods in zip codes 89085 or 89084, the standard North Las Vegas calendar applies with amplified intensity during March—May and September—October.
The undeveloped desert terrain directly north and east of these neighborhoods supports large populations of wild Africanized colonies. During spring swarming season, those colonies dispatch scouts into residential areas in significant numbers. Homes along the desert border consistently generate higher call volume during peak season than homes in the central valley.
What to Do Seasonally
Before spring (January—February): Inspect your exterior walls, weep screeds, block fences, and roofline gaps. Seal any obvious openings with appropriate mesh or caulk. If you had a colony removed in the past year, verify the repair work is intact.
During spring peak (March—May): Watch for swarm clusters on your property and respond quickly. A swarm on your fence that you address within 24 hours is a $150—$250 swarm removal. The same swarm three weeks later is a $350—$650 wall extraction.
Summer (June—August): Be alert for signs of an established colony you might have missed — buzzing from walls, consistent bee traffic at a single point, honey staining. Address before the colony grows further.
Fall secondary season (September—October): Same vigilance as spring. Check that any swarm activity is addressed before colonies establish for the winter.
