To avoid any issues you should keep your pets out of the area while you are applying Sevin and you can allow them back in the area after the application has dried. As long as you follow the
product label instructions there is only a very small amount of pesticide over any given area, only enough to kill insects not enough to harm a mammal. According to the Sevin product label: Mix 3.0 fl. oz. of product per gallon of water and spray upper and lower leaf surfaces and between fruit clusters and on small limbs and trunks to the point of runoff where pest appear. Repeat applications as necessary up to a total of eight times per year for tree fruits or five times per year for small fruits, but not more often than once every seven days.
