You are correct. Martins IGR can be mixed with Viper. Specific label instructions still apply to each product. If you find that you are needing to treat areas that Viper cannot be applied, you will need to apply the products separately. You should not apply either of these products on bedding, mattresses, or the skin contact areas of couches or other furniture.
Mopping would remove any residual of the Martins IGR, so waiting as long as possible would be recommended. If treating something other than fleas, applying Martins IGR as a crack and crevice application along baseboards, windows, under cabinets, behind appliances, etc to get the full benefit of the residual. You may reapply ever 60 days for preventative treatments, or as needed for active infestations.
If you are treating for Fleas, you do not need to apply Martins IGR to wood floors as fleas do not bed or harbor there. Concentrate your applications to carpeted areas, rugs, upholstered furniture and pet bedding.
Martins IGR should only be mixed as needed and not sit in a sprayer longer than 24 hours. You really do not want products to sit in sprayers long as this can cause damage to the sprayer and products start to breakdown once mixed with water. For maintenance outside, Martins should be applied once a month, inside it has a residual of 7 months. Martin's Permethrin should also be used within 24 hours, applied once a month outside and once every 90 days inside for maintenance of general pests. For fleas you are typically applying every 2 weeks for active infestation for at least a few treatments. You can apply the products at the same time from the same sprayer.
We are sorry to hear that you are having this type of problem. The Martins IGR is only an insect growth regulator, it will stop insects from being able to reproduce, but it will not kill anything. You will need to use it along with an insecticide concentrate in order to completely eradicate for the pest you are targeting.
Martins I.G. Regulator is mixed at 1 fl. oz. per gallon of water.
The shelf life of Martins IGR is 3-5 years once it has been opened. It is recommended that you keep your product in a cool, dry environment so that it does not freeze.
Per the Martins IGR label, you will prepare a diluted spray solution by adding 1 ounce per gallon of water. Partially fill the mixing container with water, add I.G. Regulator, agitate and fill to final volume. Do not allow spray mixture to stand overnight. Mix before each use.
Either the Archer IGR or the Martin's IGR both contain the same active ingredient, Pyridine 1.3%. They both are photostable up to 14 days outside and are essentially the same product just different manufacturers. You would be able to do more applications with the Archer being in the larger bottle, but either would work the same for fleas outside.
As long as the Martins IGR has had time to dry on the surface (this usually takes 1-2 hours), it would be fine for your animals to be out on it. The soil underneath just the surface it not an issue when using this product.
Yes, Martins IGR is safe if applied according to the instructions on the product label. People and pets should be kept out of the area while the product is being applied, but it is fine for them to return when the product has dried. It is best to make sure that it does not get wet within 24 hours after application.
