HELP! How can I kill crickets?

Hi friends

I have a huge problem (it is serious for me because I have a phobia)
I hate crickets and now, there are plenty of them in the city I'm living.
How can I kill them all (do not tell me to step on them because I am worried about what happens while I m sleeping) ..
What kind of poison can I use?

Thanks
I don't need people to tell me that my fear is unfounded... search the definition of PHOBIA and you will see that it means that is an unfounded fear!!! it is not something I really know how to handle, it just happens, I don't like to have this phobia !!!!!!!!!!!
You would have the same phobia if crickets would have climbed up your legs when you were a child... it is not a pleasure, believe me.

I only need to know how to get rid of them.
Having more than 15 crickets in a small room is not normal, it is much more than nature needs... it means that their natural predator is being killed or extermined - which is not my fault -.
