Bees
What Are Bees?
Bees are flying, stinging insects belonging to the order Hymenoptera, closely related to wasps and ants. Most species are fuzzy and golden-brown with dark banding. They range from solitary ground-nesters to large social colonies. The honey bee (Apis mellifera) is the species homeowners in South Florida most commonly encounter around structures.

In South Florida, the warm subtropical climate means colonies stay active year-round with no cold-season dieback. Social species build wax comb inside wall voids, soffits, and roof spaces to store honey and raise young. Hot, humid wet-season conditions accelerate colony growth significantly, and swarming behavior — where a queen and workers split off to find a new nest site — can happen across multiple months.
For a typical suburban homeowner, the real danger is an established colony inside a wall void. Honey stored in structural cavities can liquefy in South Florida heat and cause serious moisture damage, mold, and staining. A small swarm can grow into thousands of bees within weeks, making early identification and professional removal far more straightforward than addressing an established colony later.
When Are Bees Most Active in Florida?
Bee activity in Florida follows a year-round pattern shaped by the region's warm, frost-free subtropical climate. Swarm season peaks in late winter through spring, but colony activity and structural nesting risk are present in every month.
January
Active
Mild coastal temperatures keep colonies foraging and maintaining brood.
February
Active
Colony expansion begins as queens increase egg-laying ahead of spring bloom.
March
Peak Swarms
Warm temperatures and flowering plants drive strong foraging and swarm season onset.
April
Peak Swarms
Peak swarm season; colonies split and scouts search aggressively for new nest sites.
May
Peak Swarms
Wet season approach sustains flowering; colonies remain large and highly active.
June
Active
Summer heat and abundant moisture maintain foraging pressure across the region.
July
Active
Colonies at peak population; defensive behavior increases during hottest weeks.
August
Active
Continued wet season sustains nectar sources and supports large, established colonies.
September
Active
Colony populations remain high; a secondary swarm period is possible in warm years.
October
Active
Dry season transition; colonies continue foraging as temperatures begin to ease.
November
Active
Cooler but frost-free conditions allow ongoing brood rearing and reduced foraging.
December
Active
No killing frost occurs; colonies remain intact and do not enter true dormancy.

Warning Signs of Bee Activity
Many bee problems start as a swarm or a few foragers and become a structural infestation within weeks. These are the signs that bees have moved in, or are close to doing so, around your home.
Visible Swarm
A dense cluster of bees hanging from a tree branch, fence post, eave, or exterior wall. A resting swarm is actively scouting for a permanent nest site. In South Florida, swarms can appear from late winter through fall and will move into an available cavity within hours to days if left alone.
Heavy Bee Traffic
A consistent stream of bees flying in and out of a specific gap in a soffit, eave, wall vent, or utility entry point. Forager traffic at a fixed location is a reliable indicator that a colony has already established a nest inside the structure and is actively tending comb.
Buzzing Inside Walls
An audible humming or buzzing sound coming from inside a wall, ceiling, or soffit — particularly noticeable in quieter rooms. This signals an established colony, not just passing foragers. In South Florida's heat, the sound may intensify during the warmest hours of the day as bee activity peaks.
Honey or Dark Staining
Brownish discoloration, soft spots, or wet patches appearing on drywall, ceilings, or siding. In South Florida's summer heat, honey liquefies and seeps through structural surfaces. This is a sign that a colony has been established long enough to build significant comb and should be treated as an urgent structural issue.
DIY Treatment Methods
Homeowners in Florida have several DIY options worth trying before calling a professional for bees. These steps focus on prevention and limiting access — once a colony establishes inside a structure, DIY removal is rarely safe or effective.
1
Seal Gaps in Soffits, Eaves, and Utility Entry Points
Bees need a protected void or cavity to establish a colony. Use weatherproof caulk or hardware cloth rated for exterior use to close gaps in soffits, eaves, wall voids, and pipe penetrations. Inspect these areas thoroughly before and after Florida's wet season begins in May, since heat and humidity accelerate material degradation faster than in cooler climates.
2
Wait Out a Fresh Swarm Without Disturbing It
A fresh swarm resting on a tree branch or fence has not yet established a colony. Do not disturb a resting swarm — many will relocate naturally within 24 to 72 hours without any intervention. During Florida's warm months, which run nearly year-round in South Florida, swarms can appear any time a hive outgrows its space.
3
Manage Flowering Plants and Water Sources Near the Home
Bees are strongly attracted to water and blooming plants, especially during the dry season from November through April when natural sources are scarce. Eliminate standing water in birdbaths, gutters, and container plants and reposition heavily flowering plants away from entry points and high-traffic areas to reduce foraging activity near doors and windows.
4
Install Fine Mesh Screening on Vents and Open Cavities
Covering open attic vents and crawl space openings with fine mesh screening can prevent bees from entering potential nesting sites entirely. This works best as a preventive measure before any bee activity is observed. Inspect all screening annually — South Florida's humidity and UV exposure degrade mesh materials faster than in northern climates.
DIY methods work best on early or limited activity. Established colonies inside wall voids or structural cavities almost always require professional treatment — particularly given the presence of Africanized honey bees throughout Florida, which require proper identification before any removal attempt.
Do Bees Pose Any Health Risks?
Bee stings are the primary health concern for Florida homeowners. Most stings cause localized pain, redness, and swelling that resolve on their own. A small percentage of people experience a systemic allergic response known as anaphylaxis — a well-documented and potentially life-threatening reaction to bee venom that requires immediate medical attention.
People with a known bee venom allergy should carry prescribed emergency medication and consult a healthcare provider about their risk level before any bee activity occurs on their property. Young children and pets are also more vulnerable simply because they may not recognize or avoid a threatened colony — and Africanized honey bees, established throughout Florida, respond more aggressively to perceived threats than European honey bee populations.
Your Questions About Bees Answered
Are bees in Florida active all year, or do they slow down in winter?
In South Florida, bees remain active year-round. The region's mild winters rarely drop low enough to trigger dormancy. Colonies in Palm Beach and Treasure Coast counties stay productive even in January and February. Expect consistent foraging and colony growth regardless of the season.
How do I tell the difference between bees and yellow jackets near my home?
Bees are typically rounder and hairier than yellow jackets. Yellow jackets have a smooth, distinctly pinched waist and more aggressive behavior around food. Misidentifying the pest leads to the wrong treatment approach, so confirming what you have before acting is important.
Is it safe to leave a hive alone if it's not bothering anyone?
An untreated colony will grow. A larger colony means more structural risk if they've nested inside a wall or soffit. Hives left inside walls can attract secondary pests, including wax moths and rodents, after bees leave or die. Early removal prevents compounding problems.
Why do I keep seeing bees swarm in the same spot every spring?
Swarms in Florida often appear from late winter through spring as established colonies split and scout new nesting sites. If a location has been used before, residual wax and pheromones attract new swarms. Thoroughly cleaning out old comb after removal reduces the chance of repeat activity significantly.
Can bees damage my home's structure?
Bees themselves don't chew wood, but honeycomb built inside walls causes real structural damage over time. Honey can seep through drywall, attract ants and rodents, and create mold conditions. South Florida's heat accelerates this — summer temperatures cause honey to liquefy and spread faster than in cooler climates.
Are bees dangerous to my pets or children?
Most bees only sting when provoked, but Africanized honey bees, which are established throughout Florida, respond more aggressively to perceived threats. Children and pets who disturb a nest unintentionally face real risk. Any colony near play areas or pet runs warrants professional identification before any action is taken.
Does Florida law protect bees? Can I legally remove a hive myself?
Florida does not prohibit removing nuisance bee colonies from private property, but Africanized honey bee concerns mean professional identification is strongly recommended before any removal attempt. Disturbing an Africanized colony without proper equipment and training poses serious safety risks for the homeowner and nearby neighbors.
Will bees come back after a hive is removed?
Re-infestation is common if the void space isn't sealed after removal. Scout bees detect the residual scent of old comb and signal new swarms to investigate. Complete removal of all comb and wax, followed by proper sealing of the entry point, is the most effective way to prevent return activity.
Why Professional Treatment?
Bees are difficult to eliminate without professional help because the colony itself is rarely the only problem. When a hive is removed incompletely, remaining comb, honey, and pheromone traces attract new swarms to the same location. Bees also establish nests inside wall voids and structural cavities that homeowners cannot safely or fully access on their own.
Professional treatment goes beyond removing visible activity. A trained technician can assess whether bees have established comb inside the structure, which requires a different approach than surface-level removal. In South Florida, where warm temperatures allow colonies to grow and swarm year-round, timing and thoroughness of removal matter significantly — an incomplete job in any season can lead to rapid reinfestation.
