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.
Talstar PL Granlues will not have any effect on the rooting or health of your sod and may be applied either prior to or following the laying of sod. We would recommend that you read over the product label for complete use instructions for your target pest.
Granule products like Talstar PL Granular Insecticide will only control the young stages of fleas really as these are the ones in the soil. For adult flea control, it is recommended to use sprays such as those in our Outdoor Tick/Flea Kit. We also have a great flea control article here.
As you mentioned, once the Talstar PL Granules have been watered in and have dried, it is safe for the pets to resume normal activity in the yard. Ideally, you want 6 hours after it has dried before any rain or irrigation occurs to allow the product plenty of time to stick in its place in the lawn. After that point any watering, rain or other form of irrigation will not “re-activate” the granules to make it unsafe for the pet. They can safely walk across the lawn with dew or rain after that time frame.
