Conserve SC is a great product for treating caterpillars since it is a targeted application and is very gentle on the plants and on other non-target insects and animals. If you are going to do a follow up treatment using Talstar, then I would wait at least 1-2 weeks so that you are not wasting the Conserve application since you don’t need both products at the same time.
Talstar P (Talstar One) is NOT labeled to kill horse flies or for use in pastures containing grazing animals. We recommend using Martins Permethrin 10%. Martins Permethrin 10% controls horse flies, face flies, lice and ticks, with a residual activity lasting up to 28 days. It is also safe for Horses.
Talstar P Professional Insecticide should be applied at a rate of 1 oz per gallon of water. It can be reapplied outdoors every 30 days. We do suggest mixing Talstar with an IGR to disrupt the life cycle of the insects by keeping the juveniles from growing into adults.
Talstar P is a liquid concentrate that must be diluted with water and applied using a hand or backpack pressurized sprayer. Talstar should be applied only as a spot or crack and crevice treatment indoors. Please refer to the product label for complete mixing and application instructions, as well as the required protective equipment. If you are applying inside a school, be sure to check with the governing authority on what products are allowed to be used in that environment.
We typically recommend Talstar P for general home pest control. It is labeled for over 75 different pests, so it will work for all of the ones you mentioned as well as many others. It can be used indoor and outdoors, and it is odorless, dries clear, leaves no stains, is non-irritating to the skin, and won't break down easily with rainfall. You will want to treat every 90 days indoors, and every 30 days outdoors. Please let us know if you have any other questions.
There is no valid reason to mix Suspend SC and Talstar P together. Talstar P is a synthetic pyrethroid and Suspend SC already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.
Talstar P (Talstar One) is labeled for gnat control. Be sure you are mixing at 1oz per gallon water. Are you seeing them indoors? If so, be sure to take any indoor plants out and let them dry. If having an issue outdoors, be sure you are focusing on areas that contain moisture and/or shade. Also, undersides of leaves on non-edible trees and shrubs. Keep in mind that part of the difficulty in handling flying insects is that you are relying on them to land on areas treated with the insecticide.
There is no valid reason to mix Suspend Polyzone and Talstar P together. Talstar P is a synthetic pyrethroid and Suspend Polyzone already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas, prolonging the infestation.
