Hot Topics: Did a Lizard Lay an Egg in This Light?

An outdoor light with a possible lizard nest in ti.

Here on we enjoy providing a place where home improvement novices and experts can come together to share ideas and advice. Inside our Forums, users can browse threads to see what exchanges are taking place on a topic of interest or start their own dialogue by posting something for the community to take part in. With over 250,000 members and counting, this resource is quite active so each week we highlight one of the conversations that may just help you with that next DIY project.

We seal as homes as best we can to protect them from the elements, but Nature finds a way. When some creature sets up a hatchery in your wiring, sometimes the mystery of how it happened is more important than the fix. The Forum has several good guesses, and one outstanding suggestion.

Original Post: Eggs inside electrical box

MiamiCuse Member

This is a total mystery to me.

I had to repair/replace a security light high up on the exterior wall. The electrical box is mounted on the concrete wall, there is a water tight conductor that goes to the light fixture, and a romex feeding the box from behind the wall. The box was covered with a watertight metal cover, and painted over. I had a real hard time opening it even after removing the screws.

After I opened the box, I saw some eggs inside.

See the eggs? What is it? Can't be bird eggs. Lizards? gecko? frogs? snakes?

Oh, I am in Miami Florida so that may be relevant.

How does ANYTHING live in there? It's water tight! It's sealed off.

Now if you think may be these are old eggs since 1975... no, I first opened the box three weeks ago, saw those eggs. I removed them. Then three weeks later the light was acting up again (turned out it was a photo cell but...) I opened the box and found NEW eggs.

Some reptile’s inside my box! I don't see any mommy snake or lizard hissing at me for disturbing the eggs.

Wait a minute! That "pipe" to the right of the junction box looks like it has a big crack where it enters the box. Alternatively a lizard could well be living inside the wall and come through the back hole where the Romex goes.

No crack in that fitting. It's one of these:

Hard to believe but there it is! The eggs look too large to get by the wires into the house. Does it look like there is passage via the light fixture?

MiamiCuse Member

Light fixture is mounted on the wall and connected to the box via a water tight flex conduit that comes in from the right.

I don't see how anything can squeeze through.

I live too far north to know anything about living with lizards and snakes, but I'd crack open your light fixture box and see if anything is in there. I think it would be entirely possible for a small snake or gecko to pass between boxes via your liquid tight conduit. Perhaps it made its way in through the light somehow.

Lizards like heat correct? Light makes heat one night, lizard gets curious, finds small crack to get into box.

Where is the other end of that exterior pipe? Is there any opening there? If those white balls are fuzzy they could be bundles of spider eggs.

They be lizard eggs... the little buggers will get in at any chance...

The lizard, before she creates the egg, can slither through a small opening. She then rests in the box, creates the egg which causes her to swell, then lays the egg and her body shrinks back down. Then she can exit the box.

It takes only a few days for a hen to create and lay an egg (since she can lay more than one a week). So it is reasonable to believe a lizard could do it in the same time frame.

Some lizards can also scamper up and down the inside or outside surface of the wall in order to get that high off the ground.

If the second batch of eggs had not hatched when you took them out, you could have kept them in a not too cool place and they would have hatched and you could have found out the species.

I think it’s time to call in an eleggtrician.

MiamiCuse Member

Nashkat1 the other end of that exterior pipe connects to the light fixtures. I guess something could have squeezed through the fixture box and all the way through the tight conduit.

No not fuzzy, very smooth shell.

AllanJ if I tried to hatch it it could turn into a giant T-Rex or worse, Godzilla!

“I think it’s time to call in an eleggtrician.”


Best answer so far.
