Hey stinkydogs, many different species of frogs out there but most indigenous to our region hibernate at the bottom of natural bodies of water. comettose gave you good sound advice all factors considered which includes your location and the depth of your pond. Stock tank heaters are very expensive to purchase as well as to run over winter and so are de-icers not to mention the costs of all the materials you need at the bottom of the pond to keep them from resurfacing in the dead of winter. I don't know how big your pond is but there are people out there who have smaller pre-form ponds who place sheets of plywood over them to keep frogs out. Not a good idea to do this if you are overwintering fish or plants that need to photosynthesize in your pond but a quick fix for the basic water feature type pond. Very inexpensive fine mesh synthetic netting in 4' (folded which gives you an eight foot width) widths can be purchased at fabric stores and staked down around decent sized ponds. I did that one year and it kept them out pretty good but you have to stake it down taught. I found one big bullfrog sitting in the middle of my netting with his lower half sunk in the water but he couldn't get to lower depths and had to ultimately move on to bluer and murkier pastures so to speak. Butterfly nets work fine to get the frogs. The handles are long enough to chase after them under water. One other possibility is to offer any neighborhood kids a buck or two a piece to gently round them up.

Call me the mighty cuban tree frog hunter! :o) I saw him hanging out on my yard art and after a few attempts captured him in a cool whip container. He's now chilling out in the freezer. We were able to confirm the big toes. Tomorrow night I'll get a picture and send an email to the University of Florida extension service for mapping. I hope I don't have many more of them.

Sahoyaref Have no idea ,was just told this by a fellow customer at HD.lol He was using it for its intended purpose to fill spaces in walls. Between plumbing lines in his case. He said that after 3 years he had to buy more as it had shrunk away from the pipes. He also told me it could not be kept constantly wet.So far have not noticed any difference between material underwater,constantly dry and constantly wet nor has there been any loss in adhesion. It will setup and cure underwater though adhesion is very poor. It's also a lot softer and spongier. Even if this proves to be true I don't see any problem. How could a terrarium go 3 years without a major overhaul anyway??lol I'm helping a friend create a rockface for Rift lake cichlids using the super expanding type. All kinds of caves and crevices at the touch of a button and the really great thing is almost no weight. This tank is 96x24x24 deep so you can imagine how much rock that would require.Not to mention the cost!! It is going to be difficult to paint where it adheres to the glass used a layer of black silicone before the foam which will be trimmed around the faces.. You could use various colored silicone to get a more mottled effect but went with black as he thinks it looks fine. Would love to try it to make Coral platforms for marine setups. Imagine having the exact size and depth and stability. So far nobody will allow me to use it in their reeftanks lol. Have found no chemical reactions in FW in 3 months. Personall,i believe if the swings are going to occur they would happen in the first week. Have not had a single fatality of plant or animal. gary

Do you have a photo? There aren't really any solid black frogs or toads in the Tulsa area, although some species can look dark from a distance.
