Iguana Behavior in Yards

Iguanas are herbivores that wreak havoc on vegetable gardens and decorative plants. Additionally, burrows created by iguanas in backyards can tear up well-manicured lawns, creating eyesores and safety hazards. Since they face few natural predators or competitors in the wild, populations have expanded in recent years. This can be a problem for homeowners, as the pests are difficult to exclude from lawns due to their superior climbing and digging abilities.

Health Risks

When iguanas in backyards are caught eating flowers, shrubs, and other plants, homeowners will sometimes pick them up by hand for relocation. This is not recommended, as iguanas are carriers of Salmonella. This infectious bacteria can be passed to humans by any contact with the animals or their droppings. Among the more severe symptoms of this illness are vomiting, fever, and debilitating diarrhea. After contact with iguanas or their fecal matter, homeowners should wash their hands thoroughly.

Lawn Damage

Additional issues are created by iguanas in yards when the pests sunbathe atop patios, sidewalks, and seawalls. Not only do they create the need for messy and dangerous clean up, but the pests frequently get in the way of passing pedestrians. When an iguana in the backyard feels threatened by people, it may bite, scratch, or deliver powerful slashes with its muscular tail. Burrows dug along seawalls or against sidewalks and foundations can also cause structures to collapse, potentially endangering residents.

Solving the Problem

Some homeowners choose to coexist with iguanas in the backyard, but for many this simply isn't an option. These territorial creatures are unlikely to simply leave on their own, so it may be necessary to install cages or fences around valuable crops and remove shelter like piles of rocks and firewood. Make sure any fencing is slanted outwards and buried at least a foot underground to keep iguanas from simply digging underneath. The best way to control iguanas in the backyard is to call the wildlife control experts at Critter Control, as they have the experience and equipment to get the job done safely.

It has been very effective at reducing the number of mice, lizard, and snake sightings. During one visit Edgar removed a rattlesnake he came across. We may see a snake maybe two to three times during the spring and summer months, but it has been far less than before.

Full service. Excellent job of extracting raccoon, cleaning all animal waste, sanitizing, and spraying anti-parasitic substance. They closed all potential ports of entry, though the work did not match the vinyl, and it looks kind of tacky. They added blown insulation, which added a lot to the cost. They provide a one year warranty against animal intrusion, with an option to extend the warranty at the end of each one- year period. They were willing to work with me one the price. I will probably extend my warranty, and will definitely use them it the future.

I was really impressed by these guys. Got a call within a few hours of making an inquiry. Had a rep out to inspect the situation by the end of the week, and when they laid out the timeline they kept if not exceeded listed times.

Rob, Travis, and Jim were all professional, polite, and courteous and after months of hearing squirrels in my ceiling they are gone and the repair to my flashing looks excellent. Can't recommend these guys enough.

Critter Control did a great job of evaluating our house for sites of entry after we found bats and a squirrel in our attic. They completed their work promptly and professionally.

We heard some noise from the corner of our house. Concerned that it could be inside we called for an inspection. Jessy arrived as scheduled and conducted a complete inspection of our home. Based on a recording we made he determined we had a tree frog on our roof. I was pleased that we didn’t have any rodent in our house. And his inspection could a few spots I can tighten up around my house. I am very happy with the outcome.

We have a vacation home in Western Mass and haven’t been there much during the pandemic as we live and work in Atlanta, GA. On our most recent visit we noticed that we had some rodent intrusion as well as some un-welcomed wildlife who decided to make our vacation home their home.

We contacted Critter Control and Mr. Cahoon was quick to set up an appointment as we wouldn’t be in town very long. He came out and assessed our issues. He informed us of our options to both eradicate and control future intrusions. Keeping in mind that wildlife is wildlife! He quickly got to work eradicating the rodents and wildlife from our home and addressing the intrusion issues. We feel much better leaving our vacation home for periods at a time knowing that Mr. Cahoon and Critter Control did their job and did it right! Thanks again!

We bought an old cabin last spring , it was used for years as a summer vacation cabin, therefore maintenance wasn’t a priority. After our project to remodel started, we found evidence of mice droppings.

We immediately called Critter Control and they came and gave us a reasonable estimate to remove all remnants and insulation. They sanitized and replaced with new insulation and sealing up points of entry .

Seeing their professional work made us feel confident and secure that the problem was solved ! Everyone we worked with continued to show professional and respectful work. Highly recommend this company! We continue to use critter control monthly to be sure we are mice and bug free!
