This little zapper is pretty good at killing smaller flying pests but bees and wasps are too big to be killed by the initial zap and will often only stun them untill they park their face on the zapping cage and cook for a minute. Still good for flies and aphids though.
One issue I forsee is that it doesn't have an on/off button for the UV light. It's always on if the unit is plugged in. There is a switch for the LED lamp light but not the UV light for some reason.
