In extreme cases the windpipe can close

"It was a particular favourite of mine.

"I can't handle them any more for health and safety reasons, because they flick their hair if they are distressed or irritated.

"If I was to inhale the fur it could cause my windpipe to swell up and it could be very dangerous."

Zoo insect expert Adrian Durkin told BBC Radio WM: "It is possible to be allergic to the spider fur.

"In fact they intend that you should be allergic to them - it's one of the spider's defence mechanisms."

He said handling such spiders causes them to discharge the minute hairs which cause intense irritation especially on sensitive areas of the skin.

Mr Durkin said: "Inevitably when you handle a spider like this, a few of its hairs are going to come out on your hands.

"If you put your hands anywhere near your face this will bring on the same allergic reaction."

In extreme cases, the hairs can cause the windpipe to swell dangerously.
