The bottle says don't let sit overnight. Just wondering how long in hours after the mixture goes bad once its been mixed with water. Also how often should I reapply the product? Reapplying example: Daily, Weekly, Monthly mixed w/ water Example: 8hrs, 12hrs, 24hrs. I'm also using Martin's Permethrin mixed with the the IGR in the same bottle. Will this still help with controlling the flea life cycle when used together? Thanks so much!
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.
