If you’ve ever spotted a tiny lizard darting across your patio, basking on a fence, or hiding in your flower bed, you’ve probably wondered: what do backyard lizards eat? These fascinating reptiles are more than just garden visitors — they play an important role in your yard’s ecosystem.

Understanding their diet can help you create a more lizard-friendly garden and even use their presence to your advantage for natural pest control. Let’s explore what backyard lizards eat, how they hunt, and ways to keep them happy and healthy in your outdoor space.

Why Lizards Are Good for Your Yard

Before we dive into their menu, it’s worth appreciating why backyard lizards are beneficial.

🐛 Natural Pest Control: Lizards feed on insects, helping reduce populations of mosquitoes, flies, beetles, and spiders.
🌱 Chemical-Free Balance: They reduce the need for pesticides and help maintain a natural ecosystem.
🦎 Biodiversity Indicator: A thriving lizard population often signals a healthy, pesticide-free garden.

So, if you see lizards hanging out in your yard, it’s a good sign — not a problem!

The Typical Lizard Diet

Most backyard lizards are insectivores, meaning they primarily eat insects and small invertebrates. However, some species are omnivorous or even herbivorous, depending on their environment and size.

Let’s break it down by food type:

1. Insects (Main Food Source)

The majority of backyard lizards feed on insects they can easily catch and swallow. Common prey includes:

🦟 Mosquitoes – A favorite snack for small lizards.
🪰 Flies and gnats – Easy to catch near compost or damp areas.
🐜 Ants – Eaten by many smaller species.
🕷️ Spiders – Especially common in corners or under leaves.
🦗 Crickets – A high-protein food source.
🐛 Caterpillars and grubs – Soft-bodied and easy to digest.
🪲 Beetles and moths – Common in outdoor lights and gardens.

These insects make up 80–90% of a typical backyard lizard’s diet. They’re abundant, full of protein, and easy to find around plants, mulch, and rocks.

2. Worms and Slugs

Some ground-dwelling lizards, like skinks, enjoy soft-bodied invertebrates such as:

Earthworms
Mealworms
Slugs
Snails (smaller species)

These provide moisture and are an excellent source of calcium and protein. You’ll often see lizards hunting them after rainfall when worms come closer to the surface.

3. Other Small Creatures

Larger backyard lizards — such as anoles or geckos — may also consume tiny vertebrates or eggs if available. This includes:

Small frogs
Insect eggs
Baby spiders (spiderlings)
Occasionally, other smaller lizards

Though rare, these opportunistic meals can supplement their insect diet.

4. Plant Matter (For Some Species)

While most backyard lizards are meat-eaters, some species — particularly omnivores — nibble on plants. This is more common in warmer regions where vegetation is abundant.

They might eat:

Tender leaves
Soft fruits (berries, bananas, mango bits)
Flower petals
Pollen or nectar

If you notice a lizard munching on your plants, it’s usually sampling for moisture or nutrients, not causing real damage.

What Baby Lizards Eat

Baby lizards (hatchlings) have similar diets but focus on smaller, softer prey. Their tiny size limits what they can swallow, so they prefer:

Fruit flies
Small ants
Pinhead crickets
Aphids
Springtails

Providing shallow water and avoiding harsh pesticides helps young lizards survive their first few weeks in your yard.

How Lizards Hunt

Backyard lizards are skilled hunters that rely on stealth and speed.

They use a “sit and wait” strategy — staying still until prey moves close, then striking with lightning-fast reflexes. Their sticky tongues or quick jaws help capture insects before they escape.

Many are cold-blooded, meaning they’re most active during the warmest parts of the day when their metabolism is higher. You’ll often see them sunbathing on rocks or fences to soak up heat before hunting.

How Often Do Lizards Eat?

Feeding frequency depends on size, age, and temperature:

Small lizards: Eat daily or every other day.
Large lizards: Eat several times per week.
Cool weather: Less frequent eating (metabolism slows).

In winter, some species go into brumation (a reptile form of hibernation) and may not eat for weeks or months.

What Lizards Don’t Eat

There are a few things lizards avoid or can’t digest:

Grass or tough plant stems
Seeds and nuts
Processed food
Bread, cheese, or meat scraps
Chemical-laced insects (from pesticide use)

Avoid feeding wild lizards human food — they get everything they need from natural sources.

How To Attract Lizards to Your Backyard

If you want to welcome these helpful pest-eaters, create a lizard-friendly habitat:

✅ Add Rocks & Logs – For basking and hiding.
✅ Plant Native Shrubs – Provides shelter and attracts insects.
✅ Provide Water – A shallow dish or birdbath helps hydration.
✅ Avoid Pesticides – Chemicals kill insects and harm reptiles.
✅ Create Leaf Litter Zones – Great for worms, bugs, and cover.

A diverse, chemical-free yard ensures lizards have everything they need — food, shelter, and safety.

Common Backyard Lizards in the U.S.

Depending on your region, you might see:

Anoles (green or brown) – In the South and coastal states
Fence Lizards – Across much of North America
Skinks – Found in gardens and under rocks
Geckos – Common in warmer areas, like California and Florida

Each has slightly different diets but shares a love for insects and sun-soaked spots.

Final Thoughts

So, what do backyard lizards eat? Mostly insects — and lots of them! From mosquitoes and flies to worms and caterpillars, lizards are nature’s pest control team.

By keeping your yard pesticide-free and full of native plants, you’ll create a welcoming environment for these useful reptiles. In return, they’ll help you maintain a healthy, balanced garden — one bug at a time.
