Humming birds are back

We had the hummers visit all through spring and then they were just gone. The feeder was full of ants at one point so we cleaned it up and refilled it. Turns out my husband also sprayed ant killer over the shepard's pole that we hang it on. We are not sure if that is why they stayed away. I got new nectar and cleaned it out again. As far as I can tell there are 2 little hummers that come in. Last summer we had at least 8. 

Hot day again of course. Took an afternoon nap to try to eliminate my headache. Didn't work yet. Maybe an evening walk and lots of water.
