How long can wasps survive without oxygen?
To repel wasps, spray the blend in areas where you suspect they may be. Fill a brown paper bag with air and twist off the top to resemble a wasp nest, then hang the inflated bag near the area you want them to avoid. The “nest” will keep the wasps away. If you find a wasp nest on your property, you should do the following:

Wasps don’t breath, they have a system of tubes and holes called, spiracles, trachea, and tracheoles that supply oxygen to every cell directly. Their blood doesn’t carry oxygen just nutrients and waste. Insects can open and close their spiracles block water/retain moisture/let air in again.
Not very well familiar with wasp anatomy specifically but when resting insects don’t need much oxygen. I’d imagine they’re able to just close their spiracles and hold out without fresh oxygen long enough to survive. So yes they can effectively hold their breath longer than humans because they need less oxygen.
Make sure that you are close enough to spray them powerfully but not so close that you’re likely to be stung. Spray the nest directly with the soapy water from the hose. Use all of the solution that you have in the garden hose sprayer. The soap will paralyze the wasps, and the water will drown them.
Flick your wrist quickly down on the wasp to snap the swatter. The wasp will often just be stunned, so you can scoop it up and deposit it outside, where it can either recover and fly away, or die anyway. Don’t keep swatting and mash it into the table.
Wasps, however, breathe through tiny holes in their abdomen (spiracles) which they can close off when underwater – just like humans can when holding their breath. A wasp then uses whatever oxygen they have left in their trachea in order to continue to breathe.
A wasp living indoor can live up to 10 days if it doesn’t get enough food and water. Wasps, such as Yellowjackets and Paper wasps, are warm-season insects and start to build their nest from late spring to early summer.
Drown Them Wasps causing annoyance in the garden can be drowned using a garden hose. While water will not be effective on wasps which are flying round, it can be used to eliminate underground nests and all the occupants.
If they have a nest indoors, wasps can live for months. If trapped somewhere it survives two days with air.
