Spray bottle for fly spray

Does anyone have a recommendation for a spray bottle that works for fly spray (oil based)?  Seems like whatever kind I try, they are shot in a week or 2.

Thanks for any help.

There was a dark gray bottle chemical resistant at BOOMAGGARS ,TRACTOR SUPPLY etc... It had lifetime warranty , not sure where I saw them last ...!!

Jamie,

It's called a Spray Master.  I've tried them too, and they do work awhile; longer than any I've tired.  They are a great company to work with as far as holding up the warranty...send a new one right out. 

I'm trying that sprayer right now, but each time we get done using it, take the sprayer out and empty, and put a cap on the bottle....seems to be working...

I think letting the sprayer sit in the fly spray solution is ruining it....
