Wasp Help!!

[kentosaurs]

Hey guys recently im seeing wasp at my balcony and there there are 1-2 tiny round nest about the size of a fingernail. Well i don't see a swarm of them just 1 black wasp probablu around 1-2.5cm. Normally i ignore them but now they're building a home here so should i feel "threathened" and do something about it? Last time it build its next on my plants and i just destroyed it. So is the wasp in any way harmful to me?

There is another wasp which i see rarely which is slight bigger maybe 3cm and its black/blue in colour..Anyone knows about these wasp and if they are harmful to me?

Wasp are insectivours and are considered natural pest control. However when they nest too close to humans, they are sometimes dangerous as they do induce multiple sting. Those wasp will inflict painful stings if one get stung or worst anaphylactic shock if you're allergic to it.

You have two choices, destroy it or let is be. Wasp won't harm your plant.

they looks treatening only, but won't attack you unless you treaten them, usually I saw them either in one or 2, didn't come across a swarm of wasp before, got a lot of their "hive" in my house, mostly abandon after some times, I used them as meal for mantis when I kept mantis some months ago
