Skinks are among the most common lizards people encounter around homes, and they are almost always harmless. Getting rid of them is less about extermination and more about making your property unappealing to them: reducing the habitat features they rely on, sealing the gaps they squeeze through, and occasionally trapping or relocating individuals that have settled indoors. Before taking action, it is worth knowing that many skink species are protected by law depending on where you live, and even where they are not, they eat insects you probably like even less.
Why Skinks Show Up in the First Place
Understanding what draws skinks to a property is the single most useful step toward keeping them away. Skinks are not attracted to your house the way rodents are attracted to food scraps. They are attracted to structure: physical features of the landscape that offer shelter, warmth, and hunting grounds. Research on urban reptile populations in Australia found that native reptiles were most strongly associated with fallen woody material, termite mounds, and moderate weed cover, and that this physical habitat structure mattered more than what specific plants were growing.1PubMed Central. Habitat structure is more important than vegetation composition for local-level management of native terrestrial reptile and small mammal species living in urban remnants The takeaway for homeowners is straightforward: skinks care about what they can hide under, bask on, and hunt through. The species of your garden plants matters far less than the clutter, debris, and ground cover around your foundation.
Skinks also follow their food. They eat beetles, crickets, spiders, ants, and other small invertebrates. A yard with abundant insect life, which often correlates with moisture, leaf litter, and dense ground cover, is a yard that feeds skinks. Outdoor lighting that attracts insects at night creates a buffet near your walls, and skinks learn where the easy meals are.
Habitat Modification That Actually Works
Because skinks respond to habitat structure rather than specific plants, you do not need to relandscape your yard. You need to reduce the features that serve as shelter and hunting grounds near your home’s perimeter.
- Clear debris: Woodpiles, stacked bricks, old lumber, piles of rocks, and accumulated leaf litter within a few feet of your foundation are prime skink real estate. Move woodpiles away from the house or elevate them off the ground.
- Trim low vegetation: Dense ground cover plants, overgrown shrubs touching exterior walls, and thick mulch layers all create the kind of shaded, moist microhabitat skinks prefer. Keep a clean strip of gravel or bare ground along the foundation where possible.
- Reduce moisture: Fix leaky outdoor faucets, redirect downspouts away from the foundation, and avoid overwatering garden beds near the house. Skinks need some moisture, and chronically damp soil near your walls draws both skinks and the insects they eat.
- Manage outdoor lighting: Swap white bulbs for yellow or sodium vapor lights that attract fewer insects, or move lights away from the house so the insect congregation happens farther from entry points.
These changes do not need to be dramatic. Even modest cleanup along the perimeter of your house can shift skink activity away from your walls and toward more natural areas of the yard, which is usually the real goal. Most people do not actually need zero skinks on their property; they need skinks to stay out of the house and off the patio.
Sealing Entry Points
Skinks are small-bodied and surprisingly flexible. Many common species can fit through gaps smaller than a centimeter wide. If you have skinks inside your home, something is letting them in, and finding that something is the most permanent fix available.
Start with the obvious: gaps under exterior doors, cracks in foundation walls, openings around utility pipes and wires, torn window screens, and unsealed dryer vents. Weatherstripping under doors is one of the highest-return fixes because many skinks enter at ground level. Use silicone caulk for small cracks in masonry and expanding foam for larger gaps around pipes, then trim the foam flush so it looks clean. Hardware cloth or fine metal mesh works well over vent openings where airflow needs to continue.
Garages are a common entry point because the seal under a garage door is rarely tight. If you regularly find skinks in your garage, check the bottom seal for daylight gaps and consider installing a threshold seal. Once a skink is in the garage, an open interior door is all it takes to get into the rest of the house.
Trapping and Manual Removal
When a skink is already inside, the simplest approach is manual capture. Skinks move quickly but tend to freeze when they feel cornered, and most species found around homes are small enough to catch with a cup and a piece of cardboard slid underneath. Release the animal outside, ideally in a spot with ground cover some distance from the house.
If you prefer not to handle them directly, there is good reason for caution beyond squeamishness. Skinks are prone to tail autotomy, meaning the tail breaks off as a defense mechanism. A study on an endangered skink species found that about one in ten lizards lost their tails during routine capture and handling, and that the likelihood was highest at certain body temperatures and body sizes.2CrossRef API / Journal of Zoology. Handling‐related tail loss in an endangered skink: incidence, correlates and a possible solution The tail eventually regrows, but losing it costs the skink stored energy reserves and can affect its survival. Gentle handling matters, and catching them with a container rather than grabbing them directly reduces the chance of triggering tail loss.
For persistent indoor problems, sticky traps designed for insects can catch skinks, but these present an ethical issue: the animal is stuck and will die slowly unless you check traps frequently and release caught skinks using vegetable oil to dissolve the adhesive. Live traps, such as funnel traps or pitfall traps baited with mealworms, are more humane but require more setup. Research into invasive skink management in New Zealand tested standard herpetological trapping methods at varying intensities and found that even months of intensive trapping were not sufficient to eliminate a population of plague skinks, suggesting that trapping works better for reducing numbers or catching individual intruders than for eradication.3Massey University.

Do Repellents Work?
The market for lizard repellents is crowded with products making bold claims, but the scientific evidence behind most of them is thin. Naphthalene mothballs are commonly recommended online, but they are toxic to humans and pets and have no proven long-term effectiveness against lizards. Commercial granular repellents containing sulfur, cinnamon oil, or clove oil have similarly weak evidence behind them.
One area that has received some controlled testing is citrus-based repellents. A laboratory study found that essential oil extracted from kaffir lime peel, at concentrations of 50 percent and above, caused visible discomfort in lizards exposed to it.4IOP Conference Series: Materials Science and Engineering. A Novel Green Technology Kaffir Lime Extract as Lizard Repellent That is a high concentration, and the study was conducted in a controlled setting rather than in a real home where the compound disperses and degrades quickly. Still, it lends some credibility to the folk advice about spraying citrus oil near entry points. If you try it, use it as a supplement to physical exclusion, not a replacement. A citrus spray near a gap in the wall is less effective than sealing the gap.
Ultrasonic plug-in devices sold as reptile repellents have no credible peer-reviewed support. The frequency ranges these devices emit have not been demonstrated to bother skinks, and the devices rely on the assumption that reptiles hear and respond to sounds the same way rodents do, which they do not. Save your money.
Should You Use Pesticides?
Pesticides deserve a separate discussion because the question comes up often and the answer is more nuanced than “don’t.” There are no pesticides registered specifically for skink control in most countries, so when people use chemicals against skinks, they are usually using products designed for insects or rodents, which is both ineffective and potentially harmful.
Broad-spectrum insecticides applied around a home’s perimeter will kill the insects that skinks eat, which can reduce skink activity over time by removing the food source. But this approach has collateral damage. It kills beneficial insects too, and there is evidence that common herbicides can physiologically stress skinks even at sub-lethal exposure. A study on the effects of glyphosate-based herbicides on a small skink species found that while the chemical did not kill the animals outright, exposed skinks sought out significantly warmer temperatures for weeks afterward, a behavior consistent with a fever-like stress response.5PubMed. The effect of two glyphosate formulations on a small, diurnal lizard (Oligosoma polychroma) The point is not that herbicide will kill your skinks. The point is that chemical approaches have unpredictable effects on reptiles and on the broader ecosystem around your home, and they rarely solve the underlying problem of why skinks are there.
Rodent poison bait stations are a more insidious risk. Skinks occasionally eat bait pellets or consume insects that have been exposed to rodenticide, leading to secondary poisoning. If you use rodent bait stations around your property, use tamper-resistant enclosed stations and check them regularly.
Cats and Other Predators
People sometimes suggest that keeping a cat will solve a skink problem, and cats do kill skinks. A retrospective study of wildlife admitted to three New Zealand wildlife hospitals found that cats were responsible for predation injuries across multiple reptile species, with reptiles making up about 6 percent of all native wildlife brought in after cat attacks.6PubMed. A retrospective study of native wild birds and reptiles admitted to three New Zealand wildlife hospitals due to predation by cats Cats are effective predators of small lizards, but relying on a cat for pest control comes with serious drawbacks. Cats kill indiscriminately. They do not distinguish between a pest species and a protected native species, and in areas where skinks are part of the native fauna, cat predation is a conservation concern, not a solution.
If you already have an outdoor cat and notice fewer skinks, the cat is probably part of the reason. But getting a cat specifically to control skinks would be like hiring a demolition crew to rearrange furniture. The collateral impact on birds, native lizards, frogs, and other backyard wildlife is disproportionate to the problem being solved.
When Skinks Are Genuinely Invasive
Most of the time, the skinks around your home are native species doing what they have always done. But there are situations where skinks are genuine invasive pests, and the management calculus changes. The plague skink, a small species native to eastern Australia, has established invasive populations in New Zealand and Hawaii, where it competes with native lizard species and disrupts local ecosystems. In New Zealand, biosecurity researchers have invested considerable effort in trying to eradicate plague skink populations from offshore islands where native reptiles are at risk. Their work found that standard trapping methods were insufficient for eradication even after months of intensive effort, and they explored the use of acetaminophen as a potential oral toxicant, finding it lethal to plague skinks at specific dosages.3Massey University. Developing biosecurity strategies for an invasive reptile, the plague skink (Lampropholis delicata) on Great Barrier Island
This kind of management is carried out by trained wildlife professionals using regulated methods. It is not something homeowners should attempt. The point is that even with professional tools, eradicating an established skink population is extraordinarily difficult. If you are in an area with invasive skink species and want to help, contact your local wildlife authority or biosecurity agency. They can tell you which species are present, which are protected, and what you can legally do.
Protected Species and Legal Considerations
This is the part many online pest-control guides skip, and it matters. In large parts of the world, skinks are protected wildlife. New Zealand protects all native lizard species, including skinks, under the Wildlife Act. Australia protects numerous skink species at both federal and state levels. In the United States, several skink species are listed as threatened or endangered under the Endangered Species Act, including the Florida Keys mole skink and the bluetail mole skink. Even common species like the five-lined skink may be protected in some states at the northern edge of their range.
Killing or relocating a protected species can carry significant fines. Before you set traps, apply chemicals, or hire a pest control company, identify what species you are dealing with. Take a clear photo and compare it to a regional reptile guide, or contact your state or national wildlife agency. In many jurisdictions, the legal and appropriate response to a protected skink in your home is to gently capture it with a container and release it outside, and then seal the entry point it used.
Pest control companies vary widely in their knowledge of reptile regulations. Some will happily kill skinks without checking whether the species is protected. If you hire a professional, ask specifically whether they have confirmed the species identification and whether removal is legal in your area. A company that cannot answer those questions is not the right company for the job.
When to Just Leave Them Alone
Skinks eat cockroaches, termites, ants, spiders, beetles, and mosquito larvae. A healthy skink population around your home is free pest control for insects that are far more likely to damage your property or bite you. In warm climates where insect pressure is high, discouraging skinks from your yard can mean more insects in your house, not fewer.
If the skinks are staying outdoors and your only complaint is seeing them on the patio, the honest advice is to consider whether you have a problem at all. A skink sunning itself on your front step is doing roughly the same thing your neighbor’s cat does, except the skink is also eating the ants coming through your foundation crack. For indoor intrusions, the fixes described above, sealing entry points and reducing habitat against the house, are effective and low-effort. For outdoor presence, a modest cleanup of debris and ground cover along the perimeter usually shifts activity to the edges of the yard without requiring anything more aggressive. The goal for most homeowners is coexistence with boundaries, not elimination.
