This is such an awesome hunt @anhvu No matter how much trouble these pesky mosquitoes are they are still part of the environment. We should be careful about messing with the natural balance of things. Then we also need the convenience. I've used the mosquitoes and they are fine. There are good natural products that are not harmful to the human body over long times. But it takes a lot of time to apply properly for a group.
Now we have a nice free app that is only going to cost few seconds for the whole group in the room and it's only going to drain the battery. That's so cool even if it doesn't wok on all these pesky little bloodsuckers😈
I like your saying
