Are Lizards Bad to Have Around Your House? The Truth About Lizards as House Guests

Lizards are a common sight in many households, especially in warmer regions. While some people find them fascinating and even keep them as pets, others view them as unwanted guests. The question of whether or not lizards are bad to have around your house is one that often arises, and it’s important to understand the potential benefits and drawbacks of having them around.

On the one hand, lizards can be beneficial to have around your house. They are natural predators of insects, including flies, mosquitoes, and cockroaches, which can be a nuisance and even carry diseases. Having lizards around can help to control these pest populations without the need for harmful chemicals or pesticides. Additionally, some species of lizards are harmless and even cute, making them a welcome addition to many households.

On the other hand, there are also some potential downsides to having lizards around your house. Some species can be aggressive or venomous, posing a danger to humans and pets. Additionally, lizards can sometimes cause damage to property, such as by chewing on electrical wires or leaving droppings in unwanted places. It’s important to weigh the potential benefits and drawbacks of having lizards around your house before deciding whether or not to encourage their presence.

Benefits of Having Lizards Around the House

While some people may view lizards as pests or nuisances, there are actually several benefits to having them around the house. Here are a few reasons why you should consider keeping lizards as your housemates.

Pest Control

One of the biggest benefits of having lizards around the house is their ability to control insect and pest populations. Lizards are natural predators of insects such as mosquitoes, flies, and cockroaches, which can often be found in and around homes. By allowing lizards to live in your home, you can help keep these pests at bay without having to resort to harmful chemicals or pesticides.

Biodiversity

Another benefit of having lizards around the house is that they can contribute to the biodiversity of your local ecosystem. Lizards are an important part of many food chains and can help maintain a healthy balance of species in your area. Additionally, having lizards around can be a sign of a healthy and thriving environment, as they typically only thrive in areas with abundant food and shelter.

In conclusion, while some may view lizards as unwanted guests, there are actually several benefits to having them around the house. From pest control to biodiversity, lizards can be valuable additions to any home ecosystem.

Potential Risks of Lizards in the Home

Salmonella Transmission

Lizards are known carriers of salmonella, a type of bacteria that can cause serious illness in humans. Salmonella can be transmitted through contact with the lizard’s skin, feces, or food. Children, elderly, and individuals with weakened immune systems are particularly susceptible to salmonella infection.

To reduce the risk of salmonella transmission, it is important to wash hands thoroughly with soap and water after handling a lizard or any items that have come into contact with a lizard. It is also recommended to keep lizards away from food preparation areas and to avoid feeding them in areas where food is prepared.

Property Damage

Lizards can cause damage to property, particularly if they enter homes or buildings. They may scratch or damage walls, floors, and furniture, and can also leave droppings that can be difficult to clean.

To prevent property damage, it is important to seal any cracks or gaps in walls or foundations that could allow lizards to enter. It is also recommended to keep the area around the home free of clutter and debris, as this can provide hiding places for lizards.

Overall, while lizards can be fascinating creatures to observe, it is important to be aware of the potential risks they can pose in the home. By taking appropriate precautions, individuals can minimize the risk of salmonella transmission and property damage.

Preventing and Managing Lizards in the House

Exclusion Techniques

To prevent lizards from entering the house, it is important to seal all the possible entry points. This can be done by installing screens on windows and doors, sealing gaps and cracks in walls, and using weatherstripping on doors. It is also important to keep the house clean and free of clutter, as lizards are attracted to dark and damp places.

Natural Deterrents

There are several natural ways to deter lizards from entering the house. One effective method is to use garlic. Lizards are repelled by the strong odor of garlic, so placing garlic cloves around the house or spraying garlic-infused water can be effective. Another natural deterrent is the use of eggshells. Lizards are deterred by the sharp edges of eggshells, so placing crushed eggshells around the house can help keep them away.

In addition, keeping the house well-lit can also help prevent lizards from entering, as they prefer dark and damp environments. It is also important to keep the house free of insects, as lizards are attracted to them.

By using these simple techniques, homeowners can effectively prevent and manage lizards in the house without the need for harmful chemicals or extermination methods.

Legal and Ethical Considerations

Protected Species

Before taking any action against lizards, it is important to determine whether they are protected under local or national laws. Some species of lizards, such as the Gila monster and the desert tortoise, are protected by federal law in the United States. In addition, some states have their own laws protecting certain species.

If a lizard is protected, it is illegal to kill, harm, or capture it without a permit. Violating these laws can result in fines or even imprisonment. Therefore, it is important to research the laws in your area and consult with a wildlife expert before taking any action.

Humane Treatment

Even if a lizard is not protected, it is important to treat it humanely. Killing or harming lizards unnecessarily is not only unethical, but it can also lead to ecological imbalances. Lizards play an important role in the ecosystem, controlling insect populations and serving as prey for larger animals.

If a lizard is causing a problem, such as getting into the house or damaging property, there are humane ways to remove it. For example, using live traps or calling a wildlife removal service can safely and effectively relocate the lizard without causing harm.

Overall, it is important to consider both the legal and ethical implications of dealing with lizards around your home. By following the appropriate laws and treating lizards humanely, you can ensure a safe and responsible approach to managing these reptiles.
