Spiders are milked using a pipette which sucks up their venom. This is done once every week as the spiders can get exhausted from too many milkings.

The park needs between 200 and 300 spiders to milk every year, and needs 3,000 milkings to produce enough venom for the antidote.

The venom is sent to laboratory Bio CSL where it is injected in incremental doses into rabbits.

The bunnies gradually build up antibodies in their blood, which the laboratory extracts to make a serum.

Those poor bunnies, we’re just basically biting them with a funnel web constantly to harvest their bile.
