How Do Iguana Diseases Spread?

Like other reptiles, iguanas are known to carry bacteria harmful to humans. Their intestines harbor Salmonella, and they are capable of spreading the bacteria to every surface they touch, body of water they jump into, and curious hand that touches them. Since they are often kept as exotic pets, it's important to be aware of this and follow safe handling practices. Iguanas also live in feral populations in some areas of the country, especially Florida.

Common Iguana Diseases

Salmonellosis is an infection caused by exposure to Salmonella bacteria. The illness is often transmitted by exposure to tainted food and water or by touching an infected animal and not washing hands properly. Iguanas are common carriers of the disease, passing it through their feces and saliva. Side-effects for most people include diarrhea, fever, and abdominal cramps. Thankfully, this iguana disease can be successfully treated with antibiotics. However, if not diagnosed and medicated, the infection may be fatal.


Even without touching an iguana, it's possible to pick up their disease-causing bacteria. In fact, most people contract iguana diseases through the pests' feces. Iguanas leave behind their foul-smelling droppings wherever they bask in the sun. Since lawns are a favorite place, it's easy to accidentally come in to contact with their waste. Step carefully in iguana-infested yards to avoid tracking bacteria-filled droppings into the house, wash hands thoroughly after gardening, and do not drink from or swim in water frequented by iguanas.

Safety & Removal

While their whip-like tails, intimidating size, and serrated teeth may seem like reason enough to avoid touching these pests, iguana diseases provide the best excuse to stay far away. Since they are not overly concerned with staying out of their own feces, their skin is often infected with Salmonella. As a result, any trapping or handling of the pests is not recommended without proper training and protection. To avoid possible illness, call the team at Critter Control to handle iguana removal.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
