Talstar P is a great choice for general pest control. This a non-staining, clear-drying, odorless insecticide that can be used both indoors and outdoors. It is labeled for over 75 different pests.
You should not repeat the treatment you have already made indoors using Talstar P. You can use Talstar P for flea control outdoors at a rate of 1 oz per 1000 sq ft around turf and ornamentals. Indoors, you can use a steamer or carpet cleaner to break down some of the residual application. At least 14 days after that application, we recommend retreating with a product for indoor flea treatment such as PT Alpine Flea and Bed Bug Aerosol. Be sure to vacuum well before spraying and then every day or every other day after. Please refer to our online Flea Treatment Guide for more tips on eradicating this pest.
Talstar P (Talstar One) is an insecticide, not an herbicide and will not harm any plants or vegetation. If you are looking to target Poison Ivy or Poison Oak you could use Gordons Trimec Classic or a non selective like Roundup QuikPro.
Talstar P would be your best general insecticide for your yard. It is labeled for just about any insect you could have a problem with including ants, roaches, beetles, mosquitoes, and many others. Talstar P can be used in a hose end sprayer but can be a little thick so may need a touch of water added to thin it a bit.
If you are looking to get rid of the weeds and grass so you can reseed you should use a glyphosate product such as Glyphosel Pro. This is a non-selective herbicide that will kill the weeds and anything other foliage it is sprayed on. You can reseed after 14 days. Do not directly spray the trees or allow drift to get on the trees to avoid damage.
