I have had a very small pond in my front year for about 10 years with no signs of frogs. Last year we build a bigger pond in our back yard and just 4 days after our grand opening we mysteriously had our first frog and within weeks we had about half a dozen. They are probably eastern tree frogs from my research. By the end of the summer they had populated enough that they took up residence at my neighbors pond down the street who had years previously dug a hole and put a swimming pool in the ground (without any pump)'

This year as the pond started coming back to life so did the frogs. The started croaking late in the afternoon to late at night at both mine and my neighbors ponds. Then suddenly about 2 weeks ago my frogs quick croaking, but my neighbors are still croaking each night. I can see several frogs around my pond because as I approach the pond they will make a dash in the water and boy one of them is huge and then there are several smaller ones.

The only thing I can possibly think of is I purchased some pine straw from Home Depot to put around my azaleas which I have surrounding the out perimeter of the pond. I removed all the pine straw today and haven't heard anything while my neighbors down the street are singing away. I understand frogs don't like snakes and I wonder if any might have been in the pine straw bales, but I haven't seen any. Anybody got any ideas!
Thanks!
