What you are describing sounds like springtails. They are common in bathrooms and kitchens because they can breed under the slab and follow plumbing pipes and drains into your house. You should google springtails and see if this is your issue. If it is, Talstar Liquid is considered one of the best treatments for springtails to control them, but honestly you will not get rid of the problem no matter how many products you use if you cannot find the source. The whole key to getting rid of springtails is their breeding source. You have to find it. Usually they breed under the slab and enter the home through small cracks. Unfortunately when they breed under the slab the product you apply on top of the ground like Talstar will not make it to them. The slab has to dry out and you have to do whatever you can to prevent moisture from getting under the slab. Usually springtails are breeding because of too much mulch around the house, grade against the house is not going away from the house and water puddles up, downspouts are not going away from the house, etc. Getting rid of springtails is a moisture management issue usually and not something that pesticides can get rid of alone.
Talstar P is the most popular choice for army worm control. You should spray later in the evening when the worms are most active. You will continue to see moths, but it is only the actual worm that causes damage. The Talstar P product label recommends:
"To ensure optimum control, delay watering (irrigation) or mowing for 24 hours after application. If the grass area is being maintained at a mowing height of greater than 1 inch, then higher application rates (Up to 1 fluid oz. per 1000 square feet) may be required during periods of high pest pressure"
Talstar P is labeled to treat for termites and lasts for about 5 years in the ground and works as a repellent, killing only those insects that come into contact with the treated area. A better option for subterranean termites non repellent termiticide such as Termidor SC or Dominion 2L. Termidor will last up to to 10 years in the soil and Dominion 2L will last 5-7 years. Non repellents work slower but much more effectively when treating a termite colony as they are able to be transferred thorought the entire colony therefore eventually elimating the colony. Talstar P will only repel the termites, not kill the entire colony.
Talstar P is labeled for roaches, and should do a great job helping you eliminate the infestation. We recommend that in addition to a concentrated liquid insecticide like Talstar you also use a high quality roach bait gel such as Invict Roach Bait Gel to help get the roaches that hide in places where you cannot spray (cabinets, counter tops, drawers) as well as an insect growth regulator such as Gentrol Point Source to help stop the breeding cycle of the roaches. You can purchase both of these products together in our Roach Control Kit #1.The Talstar is a residual which means it will not be a contact kill for the roaches. It could kill a roach within a few hours or within a day depending on how healthy the roach is, and how long it spent on a surface that was treated with Talstar. The spray will typically last indoors 90 days and outdoors 30 days, but for an active infestation you would want to retreat every 30 days indoors until the colony is eliminated.
