As well as tackling creepy crawlies, nasty Bushtucker Trials and snakes slithering around the camp, they've now been warned about the dangers of leeches.
The show's medic Dr Bob McCarron told The Sun: "What [the leeches] like to do on the celebrities is crawl into their socks and they do not even know it. If they walk in the rain they need to check themselves."
According to the newspaper, each of the celebs has been given an emergency pack containing a vinegar solution they can use to spray any leeches that may attach to them.
Dr Bob also told Daily Star that the female celebs were more at risk from the leeches, explaining: "They are attracted to the 'time of the month' and they're attracted to heat. If it's the time of the month, they will seek out the nearest blood supply."
As well as leeches invading camp, a poisonous snake was captured near camp this week.
As well as dealing with insects and other goodies like that, the I'm A Celeb crew were also warned about a nearby bush fire at the start of the series.
A massive blaze was raging just 40 miles from the Australian camp when the show kicked off earlier this month, but authorities insisted it posed no risk to the programme or its cast and crew.
I'm A Celebrity airs nightly on ITV.
