Talstar P (Talstar One) is an insecticide and will not affect snakes or toads.
Talstar P can be applied at any time of day.
Talstar will kill any wasp, bee, or hornet that comes into contact with a treated area. Keep in mind that this is not a contact kill product, so it can take up to 24 hours for an insect to die after contacting a treated surface. You can also use a product like Wasp Freeze as a contact kill. If you know where any of the nests are located, you can use Wasp Freeze to treat those directly as well. It is best to apply any insecticides in the early morning or evening when the wasps/bees/hornets are least active.
Talstar P would be best applied in the early morning or late evening and not during the heat of the day to prevent burning on the grass.
Talstar P should be used or discarded within 24 hours of mixing.
Neither Talstar or Bifen are labeled for dust mites and would not be recommended as they are very specific to the type of mites they will kill. Please take a moment to read our article here on "Dust Mite Control"
Chiggers are not known to infest structures and are most likely outdoors in your yard. While Talstar or Bifen are labeled for chiggers, Onslaught is typically the more recommended. Onslaught is micro-encapsulated and will last a little longer on outdoor surfaces which does give it a bit of advantage over Talstar P. Onslaught is also labeled for "mites" in general but would not be recommended for dust mites. Treatments for chiggers should begin in May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. You can also use Onslaught to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors.
All of the products are pet safe when used as directed. Pets should be out of the area during treatment until dry.
Be sure that you do not expect rain for at least 2 hours after Talstar P (Talstar One) application. Once dried Talstar leaves a residual for 2-3 months.
Talstar P will only kill those that contact a treated surface. Any new growth will not be protected and will need to be sprayed. It can be used once a month or every 7 days at the low rate.
