The honest answer: rarely
This is a common worry, and we'd rather be straight with you than upsell a problem you don't have: iguanas are rarely an attic or indoor issue. They're outdoor animals built around sun, water, and soft ground to dig in — not dark, enclosed spaces with no basking spot and no soil.
If you're hearing scratching in the attic, finding chewed wiring, or seeing insulation torn up and nesting material pulled together, that's the signature of rodents or raccoons, not iguanas. Those are the animals that actually den in wall cavities and roof spaces and gnaw structural components.
What iguanas will occasionally do indoors
There are exceptions, but they're the wandering kind, not the nesting kind.
- Wander in through an open door, garage, or a gap in a screen and need to be shooed out
- Get stuck inside a pool cage after climbing in over the top
- Bask on a lanai, balcony, or window ledge
- Very rarely, take shelter in an open garage during a cold snap
Match the animal to the damage
Because the fix is completely different for each animal, it's worth identifying the culprit correctly before calling anyone. Iguana damage is an outdoor story — burrows, banks, droppings on decks and docks, chewed plants, basking on hardscape. Attic noise, chewed wires, shredded insulation, and interior nesting point to rodents or raccoons, which is a separate service entirely.
Getting this right saves you paying for the wrong solution to the wrong animal.
Common questions
Could the noise in my attic be an iguana?
Almost certainly not. Iguanas are outdoor baskers and burrowers with no interest in dark enclosed spaces, so attic scratching, chewed wiring, and torn insulation point to rodents or raccoons instead.
Do iguanas nest inside walls or roofs?
No. They nest in burrows dug into soft outdoor soil, not in wall cavities or roof spaces, so interior nesting material is a clear sign of a different animal — typically a rodent or raccoon.
An iguana got into my house — is that normal?
It happens occasionally when one wanders through an open door, garage, or screen gap, or gets stuck in a pool cage. It just needs to be removed; it doesn't mean iguanas are living inside your home.
