No, Talstar PL Granules is an insecticide, so it has no effect on germinating grass or turf whatsoever. It will not harm, inhibit, or promote any kind of growth in turf grass.
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 Granular Insecticide can be put down then the ground is not frozen and you have active pests. Typically above 55 is best but if pests are active and there is no snow you can use.
Talstar PL granules should be applied and watered in. Applying the product to wet soil will not activate them.
The active ingredient in Talstar PL granules is bifenthrin, which is a residual non-selective insecticide. The residual could harm non-target insects like bees if they were to come into contact with enough active ingredient for several weeks after application. However, since this is a granule insecticide that is applied directly to the ground and then activated with water, it is very unlikely any pollinators like bees would actually come into contact with the treated areas. The bigger risk would be from sprays, so we recommend applying sprays in the morning or evening when pollinators are less active, as well as avoiding spraying blooming plants to reduce risk to pollinators.
No, Talstar PL granules should not be used in a flower bed. It is labeled mainly for turf use.
We would recommend using Bifen IT for your ornamental plants. It can be sprayed directly on the plants and is labeled specifically for millipedes as well as various other pests as well. You will use 1 oz. of the solution per gallon of water.
Pets and people need to stay out of the area being treated while the Talstar PL granules are being applied and watered in, but they are safe to return as soon as the treated area has completely dried.
