That's a good idea; throw gasoline on your house and light a match. You're right, the bees will no longer be your problem.

Not when they're wasps and hornets, living in/on my house. I killed as many carpenter bees as I could (and hired an exterminator to help) last spring. I'm sure I'll be back at it again next spring.

Lasered grasshoppers vs accidentally blinded farmers.. mmmmm :| And if things get too dry, crops might catch fire from lasered grasshoppers? Maybe a laser detect/laser burn bug system will do better in a greenhouse.. Dunno..

Yeah.. I've started this thread off in quirky way.. But sometimes that's how things get invented. Example: The thought of 'a windshield that can blink'..leads to the invention of the intermittent wiper. Laser diodes are now powerful enough to kill bugs.. The question is: Can solid state lasers perform a pest control role? Or at the very least be an amusing geek toy to sniper the occasional house fly.

It's like firing a laser is like firing a gun..

I piped Hydrogen Sulphide into a wasps nest. Killed them, though I was stung a couple of times. Then I burnt the nest. Smelly though. I recollect Calcium Carbide being used to kill wasps - I presume it was the Acetylene, though as I was only 9 or 10 at the time I cannot be 100% confident of this.

Might've been a similar product. I recall calcium phosphide has been sold for killing moles and the like. Moisture causes it to release phosphine ("hydrogen phosphide" as it were), which bears a strong resemblance to your above comment. Phosphide is a major impurity of carbide, which doesn't really mean all that much (it could be parts per million, which would be fairly pure actually), but because it's so poisonous and smelly, it's a notable component of the stuff.

farmers do not spend a long time in growing fields -the system can be turned off.

Unlikely - point it skywards or horizontal above the crop, and with enough energy to fatally injure, not incinerate. Turn them into fertilizer.

think of it from the police viewpoint; a laser spot on their body could be a GUN-mounted laser,and thus a deadly threat. from the pilot's viewpoint; trying to fly (to keep the AC in the air)after being blinded is rather difficult.Thus a lethal threat. ISTR a few people in the US being prosecuted for shining laser pointers on aircraft,IIRC,police helos that were hovering in the area.
