Haver flea

Haver fleas were a type of flea. Around 160 BBY, a planetary outbreak of haver fleas occurred on the planet Banchii. At the same time, Jedi Master Vernestra Rwoh was on the planet Thelj to investigate the illegal manufacturing of four-seven nullifiers, devices that could disrupt lightsabers. Rwoh decided she needed access to the Jedi Archives, and while speaking with Jedi Master Yaddle via hologram, Rwoh asked if Banchii's Jedi temple was the closest to Thelj. Yaddle confirmed that it was, but because the temple was preoccupied with a number of issues, including the haver flea outbreak, she recommended that Rwoh instead visit the temple on the planet Hynestia, which she did.
