I live in Oklahoma. I just recently started having TruGreen come out and spray the yard. I signed up for a year long program for 8 applications.... Today they came by and did a touchup with MSMA.... I was told by TruGreen that it would be safe to let my dog back on the yard after it drys, which would take about 30 minutes. However, I have decided that I will keep my pet in for 24 hours after application... Last year I used some Roundup on the yard and I think that is what made my pet sick (very sick, causing liver problems) -- I'm wondering if people out there with more experience with this kind of stuff could advice me if 24 hours wait will be okay for the pet's safety.... Ann info will help.... thanks in advance.
