There are no toxic products labeled for frogs or toads (or reptiles for that matter), and given the highly beneficial nature of these amphibians there is not likely to be anything coming along.The reasons they are on your property are because they can find food and proper habitat, and these are probably your only means for making them go away. Take away their food and they will forage somewhere else. Take away the conditions they need for hiding all day and they will seek refuge someplace else.
Habitat modification may be the more effective way to limit frogs on your property. Frogs are mainly nocturnal, and they seek food at night when it is cooler and damper. During the day they look for cool, damp, dark places to hide. They will hide under dense shrubbery or ground covers, under logs or lumber on the soil, or under large landscape rocks and timbers to avoid the hot, dry sun. Trim shrubbery, remove thick ground-cover, stack lumber or firewood off of the soil a few inches and remove any other objects or debris that come in contact with the soil and can provide harborage. Limit watering to help eliminate moisture from your yard. You can also reduce the amount of insects (the frogs food source) in your yard by treating the grass with a residual insecticide such as Talstar PL.
