So call me crazy but I love to hear the crackle these little tennis racket type bug zappers make! Each time I hear it, I know that’s one less pesky bug. The red one is made by Texsport and we bought it at Bass Pro for about $13. The yellow one doesn’t have a label. I think I got it at Walmart for a little less. Both are battery operated and work great – if you’re swing is faster than the bug can fly. These are not toys so don’t let kids play with them. They WILL zap you!
