The gap between a bed frame and the wall provides a quiet, sheltered location that's rarely disturbed.
Since predators—and people—don't often look there, it can be an attractive nesting spot for a female lizard.
3. Darkness Creates a Safer Environment
Lizards generally prefer shaded, concealed locations over bright, open areas.
The dark space behind or underneath a bed offers protection from direct sunlight and reduces the chances of the eggs being noticed.
4. Slight Humidity Can Be Beneficial
Reptile eggs need a balanced level of moisture during development.
Hidden areas behind furniture often have less airflow, allowing them to retain slightly more humidity than exposed parts of the room.
5. Successful Nesting Sites May Be Reused
Some lizard species return to places that have worked well before.
Others even practice communal nesting, where several females lay eggs in the same protected location over time.
Could They Really Be Lizard Eggs?
Here's where things get interesting.
Although lizards do lay white eggs, most house geckos lay only one or two eggs at a time. Their eggs usually have a hard, chalky shell and are attached to a surface rather than scattered loosely.
If you found dozens of perfectly round, identical white balls, they don't closely match the appearance of typical gecko eggs.
Instead, they may be something entirely different.
Other Possible Explanations
Before assuming they're eggs, consider other common sources:
- Foam beads from a torn pillow, beanbag, or cushion
- Polystyrene packing pellets
- Plastic craft beads
- Filling material from a damaged mattress
- Decorative pellets or packaging material
Manufactured materials tend to be almost perfectly identical in size and shape, while natural eggs usually vary slightly.
Signs That Lizards Are Living Indoors
If the objects really are associated with lizards, you may also notice:
- Small geckos on walls or ceilings, especially at night
- Tiny droppings near windows or light fixtures
- Soft chirping sounds in the evening
- Increased insect activity that attracts lizards indoors
Are House Lizards Dangerous?
The good news is that house geckos are generally harmless.
They rarely interact with people and actually provide a useful service by feeding on mosquitoes, flies, moths, and other household insects.
For many homeowners, they're more of an unexpected roommate than a threat.
How to Tell the Difference
If you're unsure what you've found, inspect one of the objects carefully.
Natural lizard eggs typically:
- Have a chalky or leathery shell
- Aren't perfectly spherical
- May be lightly attached to a surface
- Can vary slightly in size
Manufactured beads or foam pellets usually:
- Are perfectly round
- Have a smooth, uniform appearance
- Are loose rather than attached
- All look nearly identical
The surrounding area can also offer clues. If the objects are spilling from damaged furniture or bedding, they're much more likely to be synthetic filling than reptile eggs.
Final Thoughts
Finding mysterious white objects near your bed can certainly be unsettling, but there's no need to panic.
While hidden spaces around furniture can provide suitable nesting locations for house lizards, a large cluster of perfectly identical white spheres is not typical of gecko eggs. In many cases, the objects turn out to be foam pellets, plastic beads, or other household materials rather than something living.
If you're still unsure, take a close-up photo of a single object and inspect the surrounding area for additional clues. A careful look is usually enough to solve the mystery—and help you sleep a little easier.
If you have the original photo of the white objects, I can also help identify them more accurately.
