Electric fly swatters can work on wasps, but it depends on the size and how much of a hit they get. I’ve found it more effective for smaller insects.
I’ve had mixed success with using electric fly swatters on wasps. Sometimes they just get stunned and fly away, so you need to follow up with another method.
Wasps can be tough, and I’ve found that the electric fly swatter might just irritate them more than kill them. It’s definitely not a foolproof method.
It’s definitely possible to kill a wasp with an electric fly swatter, but they’re a bit more resilient than common house flies, so you need to be precise.
I think an electric fly swatter could work if you’re in close quarters with a wasp, but if you’re outside or dealing with a nest, you’re better off using a different technique.
I’ve tried using electric fly swatters on wasps in my yard, but they tend to dodge the swatter. It might be better to use it indoors where they’re less mobile.
