Key Points
- Florida roaches don’t go away with one spray. You need a plan: sanitation, moisture control, sealing, and targeted baiting.
- German cockroaches are the most common “true infestation” roach indoors and they multiply fast.
- Larger roaches (American/palmetto bug, Smokybrown, Oriental) often start outdoors or in damp areas and move inside.
- Glue traps help you find the hotspots before you treat them.
- Roach bombs usually make things worse by pushing roaches deeper into walls and hiding spots.
What To Do This Week If You Have Roaches
If you want real progress fast, focus on the basics that actually change the environment roaches need to survive.
- Figure out what you’re dealing with. A German roach problem in the kitchen is a different fight than a palmetto bug that’s coming in around doors during rainy weather.
- Remove the easy food. Roaches can survive on crumbs, grease film, and pet food. Clean nightly, seal food, and take the trash out consistently.
- Cut off water. In Florida, water is often the real driver. Fix drips, dry sinks overnight, and stop leaving standing water in pet bowls.
- Start monitoring. Place glue traps where activity is likely (under sink, behind fridge, pantry edges). Don’t guess, map the problem.
- Use targeted baits in the right places and avoid random spraying everywhere. Sprays can repel roaches away from the bait and make them scatter.
If you’re seeing roaches during the day, finding egg cases, or the issue keeps returning, you’re likely past “DIY cleanup” and into a true infestation that needs professional treatment.
What Type of Florida Cockroaches Are in My Home?
There are over 4,500 species of roaches worldwide, but only around 69 of them reside in the United States. Florida homes tend to see the same handful repeatedly.
The species matters because it tells you where they’re nesting, what they’re attracted to, and which treatment strategy actually works.
How to Identify Roaches
Roaches can typically be identified by their color and shape. Roaches have an oval, rusty brown body with a reddish brown head and legs. They could be as short as 0.75 inches or as long as 3 inches.
In Florida, the most common types found in and around homes include German cockroach, brown-banded cockroaches, American cockroach (palmetto bugs), Smokybrown roaches, and Oriental roaches.
German Cockroaches
In the United States, the German cockroach is by far the most prevalent species. Because of how quickly they can reproduce (hatching 20-40 roach offspring per egg case), a single female cockroach in your home might lead to an infestation of over 30,000 pests in just one year.
A female German cockroach, in contrast to most other roach species, is able to transport her egg pouches until they are ready to hatch. Consequently, it may be challenging to contain an infestation once it has begun to spread.
German roaches usually stay close to food and moisture. Kitchens and bathrooms are the most common zones, especially behind appliances, inside cabinet voids, and around plumbing.
If you’re seeing small tan roaches with two dark stripes near the head, assume German roaches and act fast. They don’t “wander in.” They establish.
Brown-Banded Cockroaches
The brown-banded roach prefers dry, warm environments and is often found hiding in walls or appliances.
They average around half an inch in length and have a mostly brown coloration. The wings and bellies of both the male and female are marked with thin, yellow stripes.
Unlike German roaches, brown-banded roaches can show up in drier rooms and higher locations. They may hide in cabinets, behind picture frames, inside electronics, and in upper corners where you won’t think to look.
American Cockroaches (Palmetto Bug)
In most of the United States, the American cockroach isn’t the most frequent roach species, but it is by far the largest.
It also has a rather long life span, ranking among the longest at around two years.
It’s not uncommon to hear these roaches referred to as “sewer roaches” or “palmetto bugs“. They can grow to be between 1 and 3 inches long and have a brown or reddish-brown body with a pale yellow border.
In Florida, these are commonly tied to moisture and entry points, drains, garages, crawl spaces, and gaps under doors. Heavy rain and heat can push them indoors even when your home is clean.
Smokybrown Cockroaches
Smokybrown roaches are common in Florida and are often confused with palmetto bugs. They’re typically darker, more uniformly brown, and are strongly tied to outdoor harborage.
These roaches often build populations in attics, soffits, rooflines, tree canopies, and mulch beds. They’re also attracted to lights, which is why people often see them near porches and exterior doors.
If you’re finding larger roaches near entry doors, windows, or upper rooms, it’s worth checking exterior lighting and attic access points, not just the kitchen.
Oriental Cockroaches (“Water Bugs”)
Oriental roaches are commonly associated with damp, cool, and dirty environments. They’re often found near drains, under sinks, around plumbing leaks, and in areas with standing water.
If you notice roaches that seem tied to bathrooms, laundry rooms, or drain-adjacent zones, don’t skip the moisture control step. Treatments won’t stick if the environment stays wet.
What Attracts Roaches to My Home?
There is one certainty: cockroaches of any variety are undesirable in the home.
Cockroaches are a nuisance for more reasons than one: they can cause asthma attacks, contaminate food, and even transfer disease. Because of this, they can pose significant health problems.
The good news is that figuring out what’s luring roaches into your property is the first step toward exterminating them.
1. Food sources
Because they are omnivores, roaches will consume anything. They enjoy meat, oily cuisine, sweets, carbohydrates, and sweets in particular.
Simple food sources, like pet food on the floor, crumbs on the counter, or dirty dishes in the sink attract roaches the most.
Roaches also enjoy waste, so be sure to frequently remove it from the house and to keep any garbage cans sealed.
2. Shelter
Cockroaches seek sanctuary in homes.
Depending on the species, roaches may reside inside electronics, beneath sinks, behind toilets, hollowed-out wood, or behind picture frames.
They may reside behind big appliances, in the crevices of basements, or in the attic since they enjoy peaceful, abandoned places.
3. Location
Even when you’ve taken care to stay away from frequent attractants, solving an infestation of roaches can be challenging. Florida’s climate, shared walls, and exterior entry points can keep introducing roaches even in tidy homes.
To learn more about how roaches are entering your clean home, see “Why Do I Have Roaches in My Clean House?”
4. Water
Roaches require water to survive, just like any other animal, and they will enter any home, no matter how clean, to get it.
Open showers, pet water dishes, and dripping faucets are all typical roach attractants.
In Florida, small leaks matter more than people realize. A slow drip under a sink or a damp cabinet base can support an infestation even when everything else looks “clean.”
5. Landscaping
Roaches enjoy living indoors, but they will also enter your yard in pursuit of shelter, food, and water.
They will be drawn to areas with standing water, such as gutters, flowerpots, birdbaths, and areas with food supplies like fruit trees or bird seed.
Mulch beds, palm debris, leaf piles, and wood stacks close to the home also create ideal hiding zones for larger roaches.
Where Do Cockroaches Hide?
Roaches are nocturnal, making it difficult to detect an infestation until it has reached epidemic proportions. They’re masters of disguise and can squeeze through the tiniest of openings.
German roaches usually hide near kitchens and bathrooms, behind stoves, refrigerators, and dishwashers, inside cabinet cracks, and under sink voids. Larger roaches often hide in garages, attics, wall voids, and damp areas tied to drains.
If you’re only treating what you can see, you’re usually treating the smallest part of the problem.
How Roaches Enter Your Home
Roaches are drawn to your home by shelter, food, and water, but how do they enter? Roaches frequently enter homes through very small cracks and openings in doors, windows, and other places.
1. Cracks and Gaps in Windows and Doors
Roaches most commonly enter homes through cracks and holes in the doors and windows. Roaches have the ideal entry points in improperly sealed doors and partially closed windows.
2. Holes in Pipes and Vents
Roaches can enter through cracks in pipes and vents, which is another typical entry point. Roaches are encouraged to enter an older house if the vents have gaps or are improperly sealed.
3. Hitching a Ride on Furniture and Other Items
Always examine used furniture and other objects for roaches before bringing them into your home. When they’re inside your house safely, these insects can hide in used objects and hole up before coming out.
4. Drains and plumbing pathways
In some homes, roaches can travel along plumbing lines or show up near drains, especially when there are moisture issues. If sightings cluster around bathrooms or kitchens, add drain-adjacent inspection to your plan.
5. Attic vents, soffits, and roofline gaps
Smokybrown roaches and other outdoor roaches can enter through upper gaps, attic vents, and roofline openings, especially when exterior lights draw them close to the home.
How to Detect Signs of a Cockroach Infestation
Cockroach Droppings
During a cockroach infestation, the bugs’ waste products will be easy to spot. The feces of smaller roaches resemble those of coffee grinds or black pepper, whereas those of larger roaches take the shape of a cylindrical pellet.
Cockroach Eggs
Oval egg casings, or ootheca, can be spotted in unexpected places like the cracks between books or under couches.
Unpleasant Odors
An overpowering greasy or musty odor may be prevalent in severely infested areas.
Seeing roaches during the day
Roaches are nocturnal. Daytime sightings often mean crowding, competition, or a population that’s grown beyond the hidden spaces. If you’re seeing them in daylight, treat it as a serious infestation signal.
How to Get Rid of an Infestation
If you think you’ve found cockroaches in your house, it’s a good idea to get in touch with a pest control company to learn more about inspection and elimination alternatives.
The most effective approach usually follows a simple order: identify the roach type, reduce food and water, map activity, bait correctly, and seal entry points so you aren’t fighting a constant re-entry problem.
5 Methods to Get Rid of Cockroaches
1. Use Glue Traps to Identify Problem Areas
In order to find the source of an infestation and eradicate the pests, glue traps are a useful tool.
Place glue strips under the fridge, under the sink, along cabinet edges, and anywhere you’ve seen activity. Check them after a few days. The goal is to confirm hotspots so bait and exclusion work faster.
- Pros: Effective, secure for use around children and animals, and quick-acting
- Cons: They must be replaced as they fill up.
2. Set Bait Stations
Exactly what might be used to quickly eliminate cockroaches? Put out some bait.
Roaches will be drawn in by the bait’s scent and will end up eating the poison. When the roach returns to its nest and dies there, the other roaches will consume it and spread the poison to themselves.
For best results, don’t place bait where it competes with easy food. Clean first, then bait behind appliances, under sinks, and in dark corners where roaches travel.
- Pros: Rapidly effective
- Cons: Must be placed correctly and kept away from kids and pets.
3. Caulk all Entry Points
If new roaches are regularly invading your home, no amount of glue strips or bait stations will help.
Use caulk to cover cracks and gaps. Add door sweeps where light shows under doors. Seal around plumbing penetrations under sinks and behind toilets. This step matters most for larger roaches that are coming from outside.
- Pros: Highly efficient, risk-free, and cheap
- Cons: Requires periodic re-checking.
4. Use a Liquid Concentrate
Pick up a liquid roach repellent concentration from an appliance or hardware store. This powerful liquid can be diluted and then applied into nooks and cracks where roaches are hiding.
Keep this step targeted. When people spray broad areas, they often repel roaches away from bait placements and push them deeper into walls.
- Pros: Efficient and targeted when used correctly
- Cons: Avoid using around children and pets due to chemicals.
5. Hire a Pest Management Professional
If you want to get rid of roaches for good, it’s best to employ a professional service like On Demand Pest Control to do it.
A professional approach isn’t just “stronger spray.” It’s usually a combination of inspection, correct bait placement, strategic products for hidden voids, and a sealing plan so you stop reintroducing the problem.
- Pros: Proven and structured approach; safer application; follow-up support
- Cons: Higher upfront cost than DIY.
Insect Growth Regulators (IGRs)
If you’re battling German roaches, an IGR can be a game-changer. IGRs don’t kill roaches instantly. Instead, they disrupt development and reproduction so the population stops replacing itself.
When combined with proper baiting and sanitation, this helps reduce the “it gets better, then comes back” cycle that many Florida homes experience with German roaches.
Roach Bombs: Avoid if Possible
Some folks who can’t afford to hire a professional exterminator resort to using roach bombs. Roach bombs, often known as “foggers,” release a pesticide fog into the air.
We don’t advise using them. In many cases, bombs don’t reach the deep harborages where roaches are hiding. They can also cause roaches to scatter, pushing them into wall voids and new rooms, which makes the infestation harder to control.
- Pros: Fast-acting on exposed insects
- Cons: Toxic, messy, and often ineffective for hidden infestations.

How to Get Rid of Roaches Naturally: 6 Home Remedies
Natural options can help for light activity or as supportive steps alongside a real control plan. For heavy infestations, especially German roaches, baiting and professional-grade strategy is often necessary.
1. Diatomaceous Earth
Diatomaceous earth, or DE, is made of fossilized algae and works by drying out insects. Use only food-grade DE and apply a very thin dusting in cracks and voids, not piles.
- Pros: Affordable, non-spray option
- Cons: Messy and needs careful placement.
2. Baking Soda
Baking soda is often used in homemade baits. If you try this, keep it away from pets and focus on controlled placement in non-food areas.
- Pros: Cheap and accessible
- Cons: Results vary and don’t address nesting.
3. Boric Acid
Boric acid is a common roach-killing powder used in cracks and crevices. Apply lightly and keep it out of reach of children and pets.
- Pros: Effective when placed correctly
- Cons: Misuse can create safety issues and mess.
4. Borax
Borax is sometimes mixed with sugar to attract roaches. Like other powders, thin application in protected areas works better than heavy dusting.
- Pros: Affordable
- Cons: Needs careful placement and cleanup.
5. Citrus
Citrus can help repel roaches. This is more of a prevention/support step than a true infestation solution.
- Pros: Easy and safer for many households
- Cons: Repels, doesn’t eradicate.
6. Essential Oils
Peppermint and lemongrass are popular. They may help with repelling but won’t eliminate a serious infestation.
- Pros: Pleasant, supportive
- Cons: Not a stand-alone solution for infestations.
Safety: Do not use boric acid or DE on countertops, in open or drafty places, or in any area where food is cooked. Thin layers should be applied, and any observable residue should be removed quickly.
Why Roaches Keep Coming Back in Florida
If you feel like you keep “getting rid of them” but they return, one of these is usually the reason.
The moisture wasn’t fixed. A drip under a sink, damp cabinet base, or condensation zone can keep the population alive.
Baits were placed where roaches don’t travel, or sprays were used in a way that repels roaches away from bait.
Entry points are still open. A home can be clean and still have roaches if gaps under doors, plumbing penetrations, or attic openings are feeding re-entry.
Outdoor harborage is heavy. Mulch beds, leaf piles, palm debris, and exterior lighting can keep pressure on the home.

Frequently Asked Questions
-
How fast do German roaches multiply?
Very fast. One female can create a major infestation in a surprisingly short time, especially in kitchens and bathrooms with moisture.
-
Do roaches come into clean houses in Florida?
Yes. Water, entry points, and outdoor pressure can bring roaches inside even when a home is clean.
-
Why am I seeing roaches during the day?
Roaches are nocturnal. Daytime sightings often mean the population is large or hiding spaces are overcrowded.
-
What’s better: sprays or baits?
For most infestations, especially German roaches, targeted baiting is typically more effective than broad spraying.
-
Do roach bombs work?
They usually don’t solve the real infestation because they don’t reach deep hiding spots and can cause roaches to scatter.
-
How long does it take to get rid of a roach infestation?
It depends on the species and severity. Some problems improve quickly with proper baiting and sanitation, but established infestations often need a multi-step plan and follow-up.
