( Stolen Memories )

Notes:
1. The irony of the Galarans is that they're practically a mirror of the SGC/NID relationship. This story could have easily be one going the opposite way - with the NID stealing info/tech and the SGC having an attack of conscience, causing the advanced alien race targeted to not think too badly of Earth but not want to deal further with them anyway. *coughcanonTollanscough*

zoology question

What's the largest insect that is harmful/dangerous to humans? (Looking scary is bonus)

Is there anything along the size of this creature?

Japanese hornet? Tarantula Hawk Wasp? Emperor scorpion? (Ok that last one isn't a flying insect)

Do pesticides work on these things? I mean, if you mass sprayed DDT at them, will they drop dead? I assume that contact insecticides are the fastest way to kill them, right? What kind of chemical would be the fastest killer (or at least used to neutralize a big honkin' bug) without causing immediate harm to humans in the area (ignore any long term damage to environment)?
