Using just PVC pipes, you can create a home for treefrogs around your house.
PVC pipe(around 1-3" works best)
block of wood(for beating the pipe into the ground)
Taking any PVC pipe- bonus points for recycled material as long as it hasn't been used for any strong chemicals or metals- cut the pipes into the desired length. The tubes that I've used have been around two or three feet tall.
Cut the end of the pvc off at a diagonal angle to make it easier to stake into the ground.
Locate the area in which you wish to place the pipes. Areas receiving shade or partial sun are optimal. Some places to consider are under trees, in and around bushes, near ponds, and drainage areas like gutters.
You might want somebody to help you stake the tubes! Hold the pipe at a 90 degree angle from the ground, place the block over the top end, and strike with the hammer until the tubes are firmly in the ground.
If the lip of the pipes are sharp, you may need to use sandpaper to make it safe for the frogs.
Optional- paint! Use paint made for outdoor use, like deck furniture paint. Make sure it's safe to use on PVC. You may need to sand the pipes prior to application. Use artistic liberty here- make the tubes match your house, blend into the environment, or stand out with bright colors. You can paint them to look like bamboo or decorate them with bold patterns.
Enjoy the frogs! If you have any questions, leave a comment.
