Ppa and pesticides

Hey guys. I’m a first time mom and my family lives in an apartment on the second floor. Our complex had pesticides sprayed on the grass and surrounding building. My ac is currently broken so we are using a window fan to bring in air. I feel like I just subjected my baby to pesticides today and I feel like a bad mom. I didn’t know they sprayed them. I just want to protect her so bad but I know not everything is avoidable and life will happen. I’m just mad at myself that I didn’t take the fan out of the window. It was blowing all day. Ugh.
