Talstar PL Granules, when applied as directed, should not harm pets at all. There is only enough active ingredient to harm small insects. We would ecommend that you contact FMC, the manufacturer, at 1-800-321-1362 and your veterinarian for further assistance.
Talstar PL Granules are one of the most effective chinch bug treatments on the market. Chinch bugs infest the base of grass plants and are often found in the thatch layer. Irrigate the treated area with up to 0.25 inches of water immediately after application to activate (release from the granule) the insecticide. Chinch bugs can be one of the most difficult pests to control in grasses and the higher applications rates will be required to control populations that contain both nymphs and adults during the summer. It may also be necessary to remove the thatch layer if it exceeds 1 inch in thickness to allow the Talstar to penetrate down to the soil.
If you have a few small spots the St. Augustine runners might fill it in this season (of course water, fertilizer, and lots of sunshine helps). If large portions of the lawn were damaged it will likely be late spring or later of next year before the lawn recovers. Very heavily damaged areas may need to be resodded.
We would recommend using Talstar PL granules in your lawn. This will kill and prevent centipedes and various other insects. Be sure to water the product in after application. This will last 2-3 months in the soil. Talstar P would be a good choice to use around the inside and outside of your home to eliminate centipedes. Indoors you can apply Talstar P to door frames, window frames, places where utilities enter into the structure, and any other place where the insects can gain entry. Outdoors you should apply the product to door frames, window frames, places where utilities enter into the structure, around the bottom of the foundation and out onto the ground directly around the foundation. You can also limit favorable conditions that the centipedes need to thrive.
Yes, Talstar PL Granules must be watered in after application.
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.
Talstar Granules are not labeled for roach control. This is because the granules will settle at the base of the grass and then after they are watered in, will be even deeper in the soil which will minimize the chance that the roaches will contact the treated areas. You may want to consider using the liquid concentrate Talstar P so you will have better coverage to kill the roaches. The liquid will be on top of the grass and at the base to help control the roaches. The liquid can be used on and in your home as well.
The Talstar PL Granules are not labeled specifically for the control over termites so outside of using the Talstar at its normal application rates per 1000 sq/ft and watering it in, we cannot advise on that specific use. Talstar P in the liquid form however is labeled for controlling Termites and you can use it at the 0.06% solution on the label to drench the soil with.
If you apply Talstar PL Granules over mulch it can work for pests that crawl over those areas. For a more effective treatment though, we would recommend moving the mulch and applying the granules in that area, that way pests that like moisture and usually hide under mulch like centipedes, millipedes, silverfish, etc. can come in contact with the residual.
