Seems that since I put out my hummingbird feeder I have more yellow jackets and hornets that I have ever seen before in my life! I have seen the hornets drinking out of the feeder but not specifically the YJs. If they help with bugs though they can all stay. Stepped on one yellow jacket (sorry fellow GTers) though and BOY did he let me know it! Its drizzling but we are still praying for rain. Suz
