Toads

The last few nights have seen an increase in vocal activity around our pond.
Last night, it started to lose its beauty about 3 AM. I went out and in a
matter of 2 minutes counted a dozen and a half gulf coast toads (Houston,
TX). This morning the hornwort is covered with strings of eggs. On the one
hand this would indicate a healthy environment. On the other it likely
indicates that we will be inundated with toads. Any natural suggestions for
toad and tadpole control?

Thanks, John
