Also this is the first I have heard that they "spit venom". I can't find any reference to that ability prior to the latest media frenzy of articles that all quote the same phrase. Some insects can spit venom but in the absence of reliable sourcing I'm very skeptical that this is one. The larvae can spit an amino acid mixture but that's a far cry from adults spitting venom.
There could be some basis to it. Perhaps there have been some scientific studies that haven't been mentioned. I think it odd for them to wear masks to protect their eyes from spit just on the say so of news in the media. Look up 'hornet saliva' and you'll get some articles from around 2014 about alcoholic sports drinks made with giant Asian hornet saliva in it that is used by athletes to give them more power and endurance in their athletic endeavours. There are also some science articles about the saliva of the adults that is applied to the macerated meat of their prey that gets fed to the larvae because of super enzymes of some kind in the saliva that turns the meat into super-food. Maybe that saliva is like an acid that can burn the eyes but not harm the digestive tract of the larvae? I'm just conjecturing here but I'd certainly be interested to learn more about it if it is true they can spit out venom or acid in their saliva.
There's nothing mysterious about these wasps or how they behave. They are not a new species on this planet and they've been around Asia for millions of years and have been thoroughly studied by the Chinese and Japanese. Any information regarding them that is needed by American scientists is easily obtained including how and what they spit.

Can you find that information for us about what they spit? Curious minds want to know more.
They aren't wasps ..... and they don't behave like wasps either. They are an apex species of insects.
The stinger of the Asian giant hornet is about 6 mm (1⁄4 in) long,[9] which is about 4.5 mm (3⁄16 in) longer than that of a honeybee.[34] It injects an especially potent venom that contains, like many bee and wasp venoms, a cytolytic peptide (specifically, a mastoparan) that can damage tissue by stimulating phospholipase action, in addition to its own phospholipase.[33] Masato Ono, an entomologist at Tamagawa University, described the sensation of being stung as feeling "like a hot nail being driven into my leg".[9] Besides using their stingers to inject venom, Asian giant hornets are apparently able to spray venom into a person's eyes under certain circumstances, with one report in 2020 from Japan of long-term damage, though the exact extent of actual visual impairment still remains unassessed.[35]
Quote from Wikipedia
I imagine news coverage of these critters consults Wikipedia, which well could be the source of the info. I have heard the bit about spitting venom before.

How did you come to that conclusion? They are wasps. Their scientific name is Vespa which means wasp in Latin. Why would you say they don't behave like wasps? All wasp species behave a little different from each other, that's one reason why they are different species.
They're now saying that there wasn't a queen amongst the murder hornets that they vacuumed up, presumably survived. Another beeologist stated there are probably other hives as well.
