We hope all had a great 4th holiday. Now its back to reality. Its really hot, but the frogs are all over the place down here, and they will start to end up in toilets. Best way to stop them and protect your vents is Critter Quitters. They are fast to install, cut them all to roof pitch, put the screws in, head on up and put them on. Zip a few screws in and you are ready for pool time. Amazon or Homedepot.com
