Using these Repti Gear silk reptile vines is a piece of cake. First, decide where you want to place the vines in the terrarium. Areas where real plants can't grow are perfect. Then, use the suction cups provided to attach the vines to the tank walls. Your reptiles will quickly start using the vines as hiding spots. When it comes to maintenance, these vines are super easy to clean. You can gently wipe them with a damp cloth or soak them in a mild disinfectant solution. Make sure to rinse them thoroughly and let them dry completely before putting them back in the terrarium. As for safety, since the vines are made of non - toxic polyethylene material, they're safe for your reptiles. But always keep an eye on your pets to make sure they don't chew on the vines excessively. If you notice any signs of wear or damage, it might be time to replace the vines to keep your terrarium looking great and your pets happy.
