Can Iguanas Damage My Property?
When approached, iguanas may bite or 'tail whip' with blood drawing consequences. They do have teeth. The bite from a large iguana may require stitches and antibiotics. Some iguanas are carriers of salmonella, a common cause of food poisoning in humans. Accidental contact with feces on sidewalks or washed off roofs may lead to health concerns.
Sadly, yes. Iguanas do thousands of dollars in damage to landscaping every year. Their burrows and underground nests can cause issues with structures and undermine seawalls. We have seen a tennis court collapse in a section due to iguanas. They will take advantage of roof entry points and cause damage to wiring, widen holes, and often times die in attics.
