A friend with a smaller printing company was discussing summertime bug problems. I suggested salting any areas they could be accessing water or moisture. I know I have seen salt recommended as pesticide in the past. NOTE: This is an animal friendly building home to a three legged cat, some turtles, and with frequent dog visits (even mine) so real poisons are not much of an option. My reasoning is this. Insects could not live on salt water any more than humans could. Now. A) Is this reason correct? Would making water sources salty kill bugs or B) Is there other reasons why salt is not good for bugs. A quick internet search said spraying bugs with salt water can kill them, but that seems far fetched. I have seen people pouring salt into their carpets to combat fleas and on beds to combat bedbugs. I basically told my friend to dump baking soda/road or epsom salts/ or any salt in crevices or moisturized spots (under sinks, etc). Did I give bad advice? Will this help? I cannot see it hurting. Salt as a pesticide or pesticide aid?
