Ok, I had to look up what a spricket was and NO THANKS!!!
I hate crickets and grasshoppers. I'm not afraid of them because I know they can't hurt me, I just don't like the fact that they jump and have icky sticky feet. UGH!!!!

And I looked up the question can tarantula's bite. Here is a piece of info on that:

They do bite, and their bites are venomous. However, for most species, the toxicity of their venom is much like that of a bee or wasp. It is most likely to cause a nasty local reaction incluidng pain, redness, swelling. However, people can have a an allergic or anaphylactic reaction to spider bites in the same way that some people react to bee stings, and this reaction can be fatal. Also, there are few species which have a stronger venom that could potentially be fatal, or at least make the bite victim quite ill. So while tarantula bits are unlikely to be fatal, you still want to avoid being bitten, and the best way to do this is to learn about spider behavior and treat the spider accordingly. Tarantulas are wild animals, and need to be treated with respect. As a rule, however, most spiders would rather retreat than bite.
