This zapper kills a ton of bugs. It literally leaves a mound of bugs below it. It does make a decent amount of noise when it zaps a bug and ants do show up when there is a pile of bugs, but that's all in a days work. It kills that many bugs. The bulb lasts about a season and a half while running continuously. It's sturdy and easy to use while safe. You can't touch it accidentally and it's safe with children around as well.
