Methanol is generally more toxic to a wide range of animals compared to ethanol.  

I do agree with Randy, that the detergent is likely to allow penetration - maybe not so much through the waxy cuticle - although it's possible that the detergent could penetrate the wax and chitin, but from my experience, it's more likely to act like a wetting solution to break the surface tension.  - see my earlier post.  Years ago, herbicides were considered to in general, not be much of a problem to bees - unless the herbicide was applied just before a big rain.  The puddles of water laced with herbicide acted like a wetting solution, hastening drowning.
