No, Talstar PL does not kill grubs. We recommend that you treat in the Spring with something like Merit Granules. We recommend that contact your local cooperative extension office to find out what the best time to treat is in your area. If it's too late to treat and the grubs are actively feeding, then you can use Dylox 420 SL. Our article "How to Get Rid of Grubs" will help guide you.
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.
Talstar Granules such as Tastar PL Granules are labeled for use in interior plantscapes, but not small potted plants. You can use Talstar P liquid concentrate on ornamental potted plants and/or on the surfaces where these plants rest, however you will likely have better success using ant baits around these plants. Be sure that the ants are not attracted to water collecting in pots due to over-watered plants, or to honeydew produced by a sucking pest such as aphids or mealybugs on the plants. You could use a small amount of granules such as Maxforce Complete Granular Bait in and around each pot. You could also use a gel bait on the edges of pots if the ants appear to be attracted to moisture or sweets like honeydew. Maxforce Quantum would be a great choice since it holds moisture well and comes with stations.
Please refer to our Ant Treatment Guide for more tips.
Talstar PL granules should be used early to mid season to control the larvae of crane flies. This application should be made between August-February during times when the ground is not frozen. If treatments are made in March-April, they may only provide supression.
Talstar PL Granules should be applied prior to rainfall or irrigation.
Crayfish are a vital food for both fish and animals. Unfortunately, the Talstar PL Granules is not labeled for Crayfish. We suggest you use a repellent, and/or crayfish traps. The Tomahawk double door crayfish live trap - Model 405 is designed specifically for trapping crayfish.
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.
