Benzalkonium Chloride Contraindicated For Gregor Samsa's Kitchen

So, there was a cockroach in my kitchen the other day, and I didn't know where I'd left the bug spray, but if I went looking for it the roach would be sure to make its escape while my back was turned.

So I grabbed what was at hand - namely a squirt bottle of Dettol Healthy Clean Kitchen surface spray - and spritzed the filthy insect with it.

Whereupon it promptly gave up the arthropod equivalent of the ghost.


The spray is a 0.1% solution of benzalkonium chloride - the same antiseptic found in Dettol and Bactine - and supposedly more-or-less harmless, safe for use on food preparation surfaces.  The oral LD50 in mammals is given as 240mg/kg, so it would be easier to kill yourself by drinking low-alcohol beer than this stuff.

Unless you're a cockroach.

Also, my floor is very clean now.
