Venom extractor.

[hullreptilelover]

Ive just bought a venom extractor for work (just in case we have any accidents!) Ive never used one before and wondered if anyone else has and how effective you rate them.
This is a description of the one I have just bought -

Aspivenin - immediate venom extraction
Aspivenin is a special vacuum mini-pump that painlessly draws poison from insect stings and insect bites. The Aspivenin treatment works on all bites and stings as well as snake bites, bee stings, wasp stings, mosquito bites, spider bites, jellyfish and scorpion stings.

Any comments greatly apprieciated!

These work really well for bee stings, not sure about anything else to be honest as they dont really draw the "poison" out, the ones I have seen were used to draw out the actual sting without empying the stinger's venom sac (which causes the pain).
This may be different to the ones ive seen though, in which case ignore me

It states on the packaging to remove any actual stingers before using it, but this is for this brand and I know there are a few on the market so others could be different.
