The short version
Spiders in Florida are most active from late summer through fall. While most are harmless, black widows and brown recluses pose risks. Professional treatment costs $150-$400 and include interior and exterior applications, and many companies add a follow-up visit.
- Only black widow and brown recluse spiders in the US are medically significant; brown recluses are rare in Florida except in the Panhandle.
- Peak spider season in Florida is August–October, when males roam for mates and seek shelter indoors.
- Prevention starts with sealing cracks, removing clutter, and reducing outdoor lighting that attracts insects.
- Most Florida spiders are harmless and help control pests like mosquitoes and flies.
- Research: Spiders turned up in 78.5% of the 554 rooms that Bertone and colleagues inspected across 50 North Carolina homes in 2012.
For Florida homeowners, families with children or pets, and landlords who want to manage spider populations effectively. If you’ve noticed an increase in spiders indoors, found webs in corners or basements, or are concerned about venomous species, you’ll find practical, actionable advice here. This guide balances safety with cost, helping you decide when a DIY approach is sufficient and when to call a professional.
What to look for
Black widows are found throughout the state, typically in undisturbed areas like woodpiles, sheds, and garages. They are shiny black with a red hourglass marking. Brown recluses, however, are rare in Florida except in the Panhandle region. They are light brown with a violin-shaped mark on the back. Their venom can cause necrotic lesions, though bites are uncommon. The CDC notes that brown recluse bites are often misdiagnosed, and most spider bites are actually from other sources. Spiders enter homes for two primary reasons: to hunt other insects and to find shelter. Florida’s warm, humid climate supports a large insect population, making homes attractive hunting grounds. During peak season (August–October), male spiders roam in search of mates, often wandering indoors through gaps under doors, cracks in foundations, or open windows. Once inside, they may establish webs in corners, closets, and attics. While most Florida spiders are harmless, two species require caution: the black widow and the brown recluse.
- 1Frequent sightings of spiders, especially in multiple rooms or on a daily basis.
- 2Webs in corners, window frames, basements, attics, or outdoor eaves.
- 3Egg sacs—small, round, silk-wrapped clusters attached to webs or hidden in crevices.
- 4Small prey insects like flies, mosquitoes, or ants near webs.
- 5Live or dead insects accumulating in corners, indicating a food source for spiders.
- 6Finding spiders in stored items like boxes, clothing, or firewood brought indoors.
- 7Visible spider molts (shed exoskeletons) near webs or hiding spots.
Why it’s worth acting soon
- Population growth: A single egg sac can contain hundreds of spiderlings, quickly escalating a minor issue into a full infestation.
- Increased health risk: While rare, black widow or brown recluse bites can cause severe reactions, especially in children or pets.
- Property damage: Spider webs accumulate dust and can stain walls and ceilings over time.
- Psychological discomfort: For arachnophobic individuals, the presence of spiders can cause anxiety and reduced quality of life.

For black widows in garages or sheds, physical removal using a vacuum with a crevice tool is effective. Sticky traps (glue boards) placed along baseboards and in corners can capture wandering spiders and serve as monitoring tools. Replace outdoor lighting with yellow “bug lights” to reduce insect attraction. Outdoors, keep grass mowed, trim bushes away from the house, and store firewood at least 20 feet from the foundation. Vacuum regularly, especially in corners, under beds, and behind furniture. Remove clutter like boxes, piles of clothing, or stacks of paper where spiders hide. Another key method is habitat modification. Spiders can squeeze through gaps as small as 1/16 inch, so a thorough inspection of foundations, windows, doors, and utility lines is essential. The most important is sealing gaps: sealing entry points with caulk, weatherstripping, and door sweeps. Fortunately, several non-chemical methods are effective for spider control. Many homeowners or landlords prefer low- or no-chemical solutions, especially when children or pets are present. If chemical treatment is necessary, professionals can use low-toxicity products like silica gel or boric acid dust in cracks and voids, which are safe for pets once dry.
spiders activity by season.
In Florida, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure usually turns up the conditions that are letting them in. The most useful first step in Florida is to note where you have seen spiders and when they appear, because that timeline is what lets a provider focus on the right area instead of treating the whole property. Scheduling before the busy stretch, rather than after it, tends to mean faster service and a more accurate quote, and a local provider can point out the conditions that matter most in Florida.

What concerns you most about spiders in your home?
When to call for help
If you’ve spotted black widows or brown recluses, have multiple spider sightings daily, or find egg sacs and extensive webbing, it’s time to call a professional. Also, if you have young children or pets, professional treatment ensures safe, targeted application of pesticides.
What you can do yourself
For most Florida homes, especially those with children or pets, professional treatment provides peace of mind and more effective, longer-lasting results. Pros also identify entry points and underlying insect problems. Professional treatments use residual sprays that last longer and are applied to hard-to-reach areas. However, DIY products often only kill spiders on contact and don’t address hidden populations or egg sacs. Simple steps like vacuuming webs, sealing cracks, and reducing outdoor lighting can help. DIY spider control can work for minor, occasional sightings.
Where you live matters
Fall is particularly busy, with many calls for wolf spiders and house spiders entering homes. In Central Florida (Orlando, Tampa, Lakeland), the climate supports high insect populations, leading to year-round spider activity. Black widows are common statewide, but more frequently reported in rural and suburban areas with abundant woodpiles and sheds. Homes here should prioritize inspections for this species, especially in attics and crawl spaces. In North Florida (e.g., Jacksonville, Tallahassee, Pensacola), brown recluse populations are a real concern in the Panhandle. Florida’s spider activity varies significantly by region. Annual exterior treatments and periodic interior inspections can prevent infestations and reduce tenant concerns. For landlords, managing spider complaints across multiple properties requires a consistent IPM program. Here, the primary concern is often nuisance spiders like the southern house spider and cellar spider, though black widows are present in garages and storage areas. The region’s dense urban landscaping and proximity to Everglades ecosystems contribute to diverse spider populations. South Florida (Miami, Fort Lauderdale, Naples) experiences a longer warm season, so spider activity peaks later in fall (October–November). Coastal areas like Tampa Bay and Cape Coral have higher humidity, which favors web-building spiders like the orb weaver (often seen on porches and patios).
Simple ways to keep spiders away
- Seal cracks and gaps around windows, doors, foundations, and utility lines with caulk or weatherstripping.
- Remove outdoor debris like woodpiles, leaf litter, and tall grass near the house.
- Replace outdoor white lights with yellow or sodium vapor bulbs, which attract fewer insects (spiders’ food source).
- Vacuum regularly, especially in corners, under furniture, and in closets.
- Store firewood away from the house and off the ground.
- Use sticky traps in corners and along baseboards to monitor spider activity.
- Install screens on windows and doors, and repair any tears.

Questions people ask
How can I tell if a spider is a brown recluse?
In Florida, brown recluses are only common in the Panhandle; elsewhere, most brown spiders are harmless look-alikes. They have six eyes arranged in three pairs (most spiders have eight). Brown recluses have a violin-shaped marking on the back (the neck of the violin points toward the abdomen).
Are spider treatments safe for children and pets?
Always tell your technician about any sensitivities. You may be asked to keep children and pets away from treated areas for a few hours until the product dries. They typically use low-toxicity sprays, dusts, or baits. Professional pest control companies use EPA-approved products that are safe when applied according to label instructions.
How often should I get spider treatment?
Many companies will re-treat at no charge between visits if spiders return. If you have an active infestation, you may need initial treatment followed by a follow-up in 2–4 weeks. For preventive control, quarterly treatments (every 3 months) are recommended.
Will getting rid of spiders eliminate all bugs?
A comprehensive pest control plan addresses both spiders and their food sources. Eliminating spiders may temporarily reduce insect populations, but other insects like ants, roaches, and flies may still be present. Spiders are predators that feed on insects. No.
Can I prevent spiders with natural repellents like peppermint oil?
For effective prevention, focus on sealing gaps, sanitation, and professional treatments. They evaporate quickly and need frequent reapplication. Peppermint oil and other essential oils may deter spiders temporarily, but they are not a reliable long-term solution.
What should I do if I find a black widow in my home?
If you find multiple black widows, call a professional for a thorough inspection and treatment. Alternatively, spray it with a spider-killing aerosol (wear gloves). Use a vacuum with a hose attachment to suck it up, then dispose of the bag outdoors. Do not try to handle it.
Do spiders hibernate in winter?
Peak activity is in fall, but spiders can be found indoors any time of year. They may seek shelter indoors during cold snaps. In Florida, winters are mild, so spiders remain active year-round, though activity decreases slightly in cooler months.
How much does professional spider control cost in Florida?
Typical costs range from $150 to $400 for an interior/exterior treatment, depending on home size and infestation severity.
Why do spider bites often turn out to be infections?
A red, painful, spreading sore with no spider seen deserves a doctor's look, whatever pest control you also decide to do. The diagnoses can overlap and the figures describe clinic patients, not the community. In Suchard's study of 182 patients with suspected spider bites at one California emergency department between January 2006 and November 2007, published in 2011, 85.7% were diagnosed with an infection and only 3.8% with a spider bite. Because skin infections look like bites and spiders rarely bite people.
Is monthly spider control worth it?
In Florida, most spiders are harmless and beneficial, so the goal is usually to remove the webs and egg sacs and reduce the insects they feed on. In Florida, only the black widow and brown recluse are medically significant in the U.S., and they are identified by their markings.
