If you live in South Florida, you probably know that iguanas are already a common sight. But the winter of 2025–2026 could make things even more interesting or frustrating, depending on how you look at it. Experts are predicting warmer-than-average temperatures and slightly less rain than usual. Thanks to a developing La Niña weather pattern, we can expect fewer cold nights which, unfortunately, is good news for iguanas and bad news for South Florida homeowners.
Normally, cold snaps in the mid-40s help control the iguana population. They can stun or even kill some of the reptiles, naturally keeping their numbers in check. But this winter, with temperatures potentially staying warmer, more iguanas are likely to survive through the season. That means come spring, we could see a surge in breeding, leading to more nests, more hatchlings, and, ultimately, more iguanas around your property earlier than expected.
Homeowners should be aware of what this could mean. More iguanas usually lead to more damage caused by burrowing under seawalls and pool decks, roof and attic intrusions, chewed-up landscaping, and even droppings that carry Salmonella. These problems can be costly and often aren’t covered by insurance.
On top of that, these reptiles are becoming more resilient. Studies show that iguanas in South Florida can now tolerate temperatures as low as 44°F, which is lower than in previous decades. This means even if a brief cold front rolls through, fewer iguanas will be affected, and their population will continue to grow.
So what can you do to protect your property? The key is preparation. Installing barriers like IggyStop and IggyWrap can keep iguanas out of trees, off roofs, and away from sensitive areas in your yard. For safe, non-lethal solutions, IggyTrap is South Florida’s trusted name in iguana control. Acting early this season can save you time, money, and stress when the warmer weather brings more active iguanas to your neighborhood.
