My boyfriend just sprayed the whole yard with Spectracide/ Triple Strike weed killer.

It says on the container it is harmful to humans and pets!
He says after a couple of hours when it dries it is ok but I am not so sure of that. I am worried about the wild birds and squirrels if they eat the seed off the ground where it was sprayed. He does this very often and it upsets me!
I know this is a parrot site but my dogs also eat the grass and weeds when they are not feeling well!
Any info.?

Searched the web and did not come up with too much.
