If the bees are chasing your hummingbirds from the feeders, and ants are draining them, as they are mine, you can solve the problem for the most part by making a quick and cheap trap.
Take a used water bottle or soda bottle and paint several dots around the bottle about 2 inches or so above the bottom. I used a red Sharpie.
Heat a sharp instrument and punch small holes in the middle of each hole, making is just big enough for the insects to enter. I used a metal ice pick for this step. Also put a couple holes in the cap.
Cut a piece of dental floss about 5 inches long, thread it through the holes in the cap, and knot it to form a loop to hang the trap.
Pour a little nectar in the bottle, or a little fruit juice.
Twist the cap on and hang it near your feeders.
It won't take long for the pests to find the trap. It won't get every one of them, but it will decrease the number. Once they go in, very few will find their way back out.
