CLOSED: Help ID please, it's bugging me...

Singapore, Singapore

Hi everyone, i need some help identifying this little bugger from sunny Singapore. My estate is surrounded by trees, i assume they live there or at least somewhere nature.

They've been invading my house and laying eggs in holes that they come across and sealing them up with soil/dirt. The last picture is of my dehumidifer: sealed, hatched and the mess. My bookcase shelf holes, door's peephole, random screw holes are sealed by them. Once they even tried to fly into my ear and nose. Eek!

I hate to squash bugs but whenever i chase them, they out beat me and will head directly out the windows and come back some time later. Very smart creatures and they can remember my interior layout. They don't respond to insecticide either. I need to at least know their name before i can find out how to keep them away :(

The photos are not of high quality, that's the best i can do after trapping it between my window panes. The body is of a metallic green tinge.

Any help will be appreciated. Thank you!

This appears to be in the family Sphecidae (thread-waisted/digger/mud dauber wasps). Most wasps in this family have their nests in burrows in the ground or construct above-ground cells made of mud. However, there also are some species that make their nests in pre-existing cavities, such as the grass-carrying wasps found in North America - see http://ento.psu.edu/extension/factsheets/grass-carrying-wasp
About the only way to keep these at bay would be to have all windows tightly screened.

Hi Flapdoodle, thank you so much for identifying it for me! After some googling, it looks like a Chlorion lobatum. Shall read up more about them and see how i can keep them at bay.

I live on the 8th floor and we've been tolerating them for around 2 years. They come in from all the windows, so keeping them close is out of the question and installing screens is too expensive =
