Which is more likely to be deadly to insects?

[Judgement]

One of the biggest freakin mosquitos I've ever seen is on the loose and it finally landed on a wall

I was gonna spray it with a lighter and burn it up but then I remembered I was indoors so it was off to plan B

I could just smash it but I'm feeling like that isn't as entertaining as it could be, so I wanna spray it with one of these 2 things if that will kill it. If neither will have any effect I guess I'll be forced to use a boot
