Mosquito larvae in water butts
I added some washing up liquid to my water butt to see if it had any effect on the mosquito larvae, within 48hrs 90% of the larvae had been destroyed. I also sprayed my veg with liquid soap on black aphids, they also got wasted. Does this mean the old wife's tail of using a soap solution spray on pests really works. your thought's??
