Fouled water, torn screens, and a genuine health issue — here's how iguanas turn a pool and lanai into a recurring expense, and how to stop it.
A pool and screened lanai is one of the reasons people move to Palm Beach County, and it's also one of iguanas' favorite spots — sunny, sheltered, and full of warm surfaces. The damage isn't dramatic, but it's constant, and there's a health angle to it that makes it more than an eyesore.
I get a lot of pool-related calls from Boca and Delray homes where the owner has been fighting the same battle for a year — cleaning droppings, patching screens, shocking the pool — without ever addressing why the iguanas keep showing up.
The screen cage takes a beating
Pool cages and iguanas are a bad match, and the screen loses.
- Iguanas climb the frame and screen, and heavy adults tear panels or pop screen spline loose.
- Animals that climb to the roofline drop into the cage and thrash trying to get out, ripping screen on the way.
- Torn panels then let more wildlife in, so the cage stops doing its one job.
- Rescreening a large enclosure isn't cheap, and it recurs if the cause isn't handled.
The pool itself
Then there's the water. Iguanas defecate in and around pools — they're drawn to water — and a fouled pool isn't just gross. It's a shock-and-rebalance cost every time, and droppings can carry salmonella, which is the real reason to take it seriously rather than just skimming and moving on.
If you've got kids or pets using the pool and deck, the droppings are a reason to keep them off the affected surfaces until it's cleaned up properly. That's not scaremongering — it's the same hygiene logic you'd apply to any animal waste around where people swim.
The salmonella piece
I keep coming back to salmonella because people underrate it. Reptile droppings can carry it, and a pool deck or lanai floor coated in droppings is a genuine exposure surface for bare feet, crawling toddlers, and pets. Clean it with gloves, disinfect, and don't power-wash it into the pool or across a play area. I'm not a medical authority — if there's an exposure concern, that's a doctor's call — but the caution is warranted.
Why it keeps happening
The reason the pool battle never ends for most owners is that they're cleaning up after animals that live on the property. As long as there's a colony on the seawall bank or in the beds nearby, the pool and cage stay on the menu. The lasting fix is upstream — remove the residents, guard the climb routes onto the cage and roof, and keep the bank cleared so nothing refills it.
What it costs to actually solve
Rescreening and shocking a pool over and over costs more, year over year, than clearing the cause once and keeping it clear. Our single visits start from $125 and monitored programs from $99/mo, and for a pool-and-lanai problem the free walk usually shows whether it's a one-time clear-out or a property that needs monitoring through nesting season.
Questions we hear
Is iguana waste in my pool actually dangerous?
It can be — reptile droppings can carry salmonella, so a fouled pool or dropping-covered deck is a genuine hygiene concern, especially with kids and pets. Clean it with gloves and disinfect, keep people off the affected surfaces until it's done, and treat any real exposure concern as a doctor's call.
How do iguanas get into a screened pool cage?
They climb the frame and screen directly, or they climb to the roofline and drop in, then tear panels thrashing to escape. Once a panel's torn, more wildlife follows, which is why rescreening recurs until the climb routes are guarded and the residents removed.
Will one cleanup fix it?
Only if there's no resident colony feeding the problem. On a waterfront lot the pool stays on the menu as long as iguanas live on the bank nearby, so the lasting fix is removing them and guarding the cage and roof routes, not just cleaning up after them.
