- Do not chase it wildly; that usually sends it deeper into hiding.
- Close interior doors so the lizard stays in one room.
- Open an exterior door or window and gently guide it outside.
- Use a container and cardboard if you need to catch and release it.
- Seal entry points around doors, windows, vents, pipes, and foundation gaps.
- Reduce insects, because lizards often come indoors to hunt bugs.
Best First Fixes for Lizards Around the House
If you only see one lizard indoors, removal and release may be enough. If lizards keep showing up, treat it as a prevention problem. The most useful fixes are the ones that close entry points and reduce the insects that bring lizards close to doors, windows, garages, and porch lights.
| Problem | Best First Fix | Helpful Product Type |
|---|---|---|
| Small gaps under exterior doors | Close the gap so lizards cannot slip inside at night. | Door sweep or weatherstripping |
| Openings around pipes, vents, siding, or utility lines | Fill small gaps, then seal them with the right exterior material. | Stainless steel wool gap filler |
| Lizards gathering near porch lights | Reduce the insects attracted to bright white light. | Yellow outdoor bug bulbs |
| Repeated lizards indoors | Look for the insect source and the entry point together. | Screen repair kit plus pest-specific insect control |

Are House Lizards Dangerous?
Most small house lizards, geckos, anoles, and skinks are not aggressive and do not want to be near people. They are usually more interested in insects than in humans. In many homes, they are accidental visitors rather than true infestations.
The main concern is hygiene. Like many animals, lizards can carry germs on their bodies or in their droppings. You do not need to panic, but you should avoid handling lizards with bare hands, clean up droppings carefully, and wash your hands after touching surfaces where a lizard may have been.
If you find droppings and are not sure what they are, see our guide: What Does Lizard Poop Look Like?
Why Do Lizards Come Into the House?
Lizards usually enter homes for one of five reasons: insects, warmth, shelter, moisture, or open gaps. If you remove the attraction, they are less likely to keep appearing.
| What Attracts Lizards | Why It Matters | What to Do |
|---|---|---|
| Insects | Lizards eat flies, ants, moths, spiders, crickets, roaches, and other small bugs. | Reduce indoor insects and outdoor insects near lights. |
| Outdoor lights | Lights attract bugs, and bugs attract lizards. | Use motion lights, yellow bulbs, or turn lights off when not needed. |
| Open doors and gaps | Lizards slip through small openings around doors, windows, vents, and utility lines. | Install door sweeps, repair screens, and seal gaps. |
| Clutter and hiding spots | Lizards hide behind furniture, shelves, boxes, curtains, and wall decor. | Declutter walls, corners, garages, and storage rooms. |
| Moisture and shelter | Porches, bathrooms, garages, sheds, and patios can provide water and cover. | Fix leaks, reduce standing water, and trim vegetation near the house. |
Where Do Lizards Hide Indoors?
Lizards prefer dark, quiet, protected places. If one disappears inside, check areas where it can stay hidden without being disturbed.
- behind sofas, beds, cabinets, and bookshelves;
- behind paintings, mirrors, curtains, and wall hangings;
- under appliances, tables, desks, and chairs;
- inside garages, sheds, closets, and storage rooms;
- near windows, sliding doors, vents, and utility openings;
- in cluttered shelves, boxes, or piles of fabric.
A lizard is easier to remove if you keep it in one room. Close interior doors, block gaps under doors with a towel, and avoid moving quickly toward it.
Choose the Right Lizard Control Plan
The right fix depends on where you are seeing lizards. A single lizard in a room needs a different response than lizards showing up every night around the porch.
| Where You See Lizards | What It Usually Means | Best Next Step |
|---|---|---|
| One lizard inside | It may have slipped in through an open door, window, garage, or gap. | Guide it outside, then check the closest entry point. |
| Several lizards near porch lights | Flying insects are probably gathering around the light. | Switch to yellow outdoor bulbs, reduce insects, and clean dead insects from the area. |
| Lizards keep appearing in the same room | There may be a nearby gap, screen problem, or insect source. | Check window screens, seal gaps, and inspect for ants, crickets, roaches, flies, or spiders. |
| Lizards in garage, shed, or patio storage | They may be using clutter, warmth, and insects for shelter and food. | Declutter, use steel wool gap filler, improve door sweeps, and reduce insects. |
How to Remove a Lizard Safely Without Touching It
The safest method is to guide the lizard outside. This avoids harming the animal and avoids direct contact.
- Stay calm. Fast movement makes lizards run deeper into hiding.
- Close interior doors. Keep the lizard contained in one room.
- Open an exterior door or window. Create a clear escape path.
- Turn off extra lights. Keep the exit area brighter than the rest of the room if possible.
- Use a broom, cardboard, or towel as a guide. Do not strike the lizard; gently direct it toward the exit.
- If needed, use a container and cardboard. Place a clear container over the lizard, slide cardboard underneath, and release it outside.
- Clean the area afterward. Wash hands and clean surfaces if droppings were present.
Avoid harsh or unsafe home remedies. Do not use mothballs, tobacco balls, poison, cold water, homemade pepper spray, or chemicals in living areas to control lizards. These methods can be unsafe for children, pets, wildlife, and indoor air quality.
If you cannot remove the lizard safely, or if they keep returning, focus on sealing entry points and reducing insects instead of trying to kill them.
How to Keep Lizards Out of the House
Long-term lizard control is mostly prevention. If lizards cannot get inside and cannot find easy food, they are less likely to stay around the home.
Seal Entry Points
Lizards can squeeze through small gaps. Inspect the places where they most often enter:
- door gaps and worn door sweeps;
- window screens and sliding door tracks;
- vents, pipe openings, and utility penetrations;
- foundation cracks and siding gaps;
- garage doors, shed doors, and porch openings.
Use caulk, weatherstripping, mesh, screen repair, and door sweeps where appropriate.
Sealing gaps under doors
Exterior Door Sweep or Weatherstripping
A worn door sweep leaves a thin opening that small lizards, geckos, skinks, roaches, crickets, and other pests can use. Choose a sweep that fits the door width and closes the gap without dragging hard across the floor.
Sealing small gaps around pipes and vents
Stainless Steel Wool for Gap Filling
Use stainless steel wool or pest-blocking mesh for small utility openings, pipe gaps, and narrow foundation cracks, then finish with an appropriate sealant where needed. Do not block dryer vents, exhaust vents, or drainage openings.
Repairing window and porch screens
Window Screen Repair Kit
Torn screens make it easy for insects to gather indoors and for small lizards to follow. A basic screen repair kit is useful for windows, screened porches, sliding doors, and garage vents.
Reduce Insects Around Lights
Lizards often gather near porches and patios because insects gather there first. Reducing insects around lights can reduce lizard activity naturally.
- turn off porch lights when not needed;
- switch to yellow or warm outdoor bulbs;
- use motion-sensor lighting;
- keep doors closed when lights are on indoors;
- clean up dead insects around windows and doorways.
Yellow bulbs attract fewer insects
Yellow Outdoor LED Bug Bulbs
Bright white porch lights can pull insects toward doors and windows. Yellow outdoor bulbs are a simple first swap for porches, patios, and garage entries where lizards gather to hunt.
Remove Outdoor Hiding Places
Yards and porches with dense cover give lizards places to hide and hunt. You do not need to strip the yard bare, but you can reduce shelter directly against the house.
- trim bushes and vines away from siding;
- move stacked wood away from the foundation;
- remove leaf litter, boards, pots, and clutter near doors;
- avoid standing water near the house;
- keep grass and dense groundcover trimmed near entry points.
Declutter Indoor Hiding Spots
If lizards keep appearing indoors, check the spaces where they hide. Move furniture slightly away from walls, reduce clutter in garages and storage rooms, and keep boxes off the floor where possible.
Do Lizard Repellents Work?
Some commercial lizard repellents may help in limited outdoor areas, but repellents are usually not enough on their own. The best results come from combining prevention steps: sealing gaps, reducing insects, adjusting outdoor lights, and removing hiding places.
For a more practical breakdown of sprays, scent-based repellents, door seals, screen repair, lighting changes, and outdoor options, compare the best lizard repellents and exclusion products before choosing a product.
Be careful with strong-smelling DIY remedies. Eggshells, garlic, onion, coffee, and similar methods are not reliable long-term lizard control. They can make the house smell bad and may attract other pests if left around.
If you want to try an electronic repellent, treat it as an optional supporting step. Results vary, and these devices should not replace sealing, screen repair, lighting changes, and insect reduction.
Optional support only
Outdoor Sonic Reptile Repellent
A sonic repellent may be worth testing around patios, sheds, or garden edges, but it should not be the first or only fix. Use it only after closing entry points and reducing insects.
How to Keep Lizards Away From the Porch or Patio
Porches and patios attract lizards when they provide insects, warmth, and hiding spots. Start with the areas closest to doors and windows.
- Turn off unnecessary porch lights at night.
- Replace bright white bulbs with warmer outdoor bulbs.
- Clean dead insects from windowsills, porch corners, and light fixtures.
- Move potted plants, storage bins, and clutter away from the door.
- Trim vegetation that touches the porch, siding, or steps.
- Install or repair door sweeps and screens.
How to Reduce the Insects That Attract Lizards
Lizards are predators. If they are showing up often, the real issue may be an insect population around the house.
Look for:
- flies around trash or compost;
- ants around food or moisture;
- moths and mosquitoes around lights;
- crickets in garages, basements, or crawlspaces;
- roaches or spiders around clutter and damp areas.
Reduce insect pressure with better sanitation, sealed food, fixed leaks, less outdoor lighting, and pest-proofing around doors and windows. For broader prevention, see our guide to DIY pest proofing. If you can identify the insect problem, use a pest-specific guide instead of adding a general product that may not match the source.
Target Their Food Source: Insect-Specific Guides
If a specific insect is attracting lizards, tackling that pest directly is more effective than repellents. Match the target insect to the right guide:
- Best Cricket Killer Products — for crickets in garages, basements, and crawlspaces.
- Best Mosquito Killer for Yard — for outdoor mosquito reduction.
- Best Ant Killer for Home — for ants around food, moisture, and entry points.
- Best Natural Pest Control Products — for lower-toxicity indoor and outdoor options.
When Should You Call a Professional?
Most lizard problems can be handled with safe removal and prevention. A professional may be useful if lizards keep entering, you cannot find the entry points, or you suspect a larger insect problem is attracting them.
Lizards keep coming inside?
Fix the conditions that keep attracting them
If lizards keep appearing indoors, the source is usually entry gaps, outdoor insects, porch lighting, moisture, or cluttered hiding spots. Do not keep chasing individual lizards room by room. Reduce the insects first, then seal the openings around doors, windows, vents, pipes, garage edges, and foundation gaps.
Best next step: pest-proof the house perimeter and adjust porch lighting before the next warm evening.
FAQ
What is the safest way to get rid of a lizard in the house?
The safest method is to close interior doors, open an exterior door or window, and gently guide the lizard outside. If needed, place a container over it, slide cardboard underneath, and release it outdoors.
Why do lizards keep coming inside?
Lizards usually come inside because they find insects, warmth, shelter, moisture, or small entry gaps. Reducing insects and sealing gaps are the most effective long-term fixes.
Are house lizards harmful?
Most house lizards are not dangerous and do not attack people. Avoid touching them with bare hands, clean up droppings carefully, and wash hands after contact with surfaces where lizards were active.
Do lizards mean my house is dirty?
Not necessarily. Lizards can enter clean homes through open doors, gaps, windows, garages, or porches. However, food waste, insects, clutter, and standing water can make the area more attractive.
Do mothballs keep lizards away?
Do not use mothballs for lizard control. Mothballs are pesticides meant for specific labeled uses and can be toxic to people, pets, and wildlife when misused around the home or garden.
Do eggshells, garlic, or onion repel lizards?
These remedies are unreliable and usually temporary at best. They can also create odors or attract other pests. Sealing gaps, reducing insects, and removing hiding places work better.
How do I keep lizards away from my porch?
Reduce insects around lights, trim plants near the house, remove clutter, repair screens, install door sweeps, and keep doors closed at night when indoor lights are on.
Should I kill lizards in my house?
Usually, no. Most lizards are harmless and eat insects. Safe capture and release, followed by prevention, is a better approach than killing them.
Bottom Line
The best way to get rid of lizards is to remove them safely, then fix the reason they came inside. Most lizards are not dangerous, but they can be unsettling indoors and may leave droppings behind.
Start by guiding the lizard outside or using a container-and-cardboard method. Then reduce insects, seal entry gaps, adjust porch lighting, remove hiding places, and keep garages, patios, and storage areas less inviting. Avoid unsafe home remedies such as mothballs, tobacco, poison, cold water, or harsh sprays in living areas.
