One of the most interesting things to research online is how a common household cleaner can be used to reduce or eradicate flies. And find that everyone is rave about it.
Flies are more than nuisances around cattle. Basic H can be used to reduce or eliminate infestations.That cleaner is Shaklee's Basic H. Now, the common misunderstanding is that Basic H is some sort of soap. It's actually a biodegradable surfactant, derived from the natural surfactants found in corn and coconut. Basic-H is not soap or a detergent. Basic-H is 100% organic, non-flammable, non-toxic, and non-irritating (a neutral pH the same as skin, about 6.5). Basic-H is completely biodegradable, phosphate-free, non-volatile, and non-magnetic. The primary ingredients of Basic-H will quickly convert within a few days to water and carbon dioxide when in contact with natural bacteria in water and soil.
Surfactants make water "wetter". But it really just means that it reduces the normal tension water has, and so allows it to interact with other elements and minerals more effectively. Basic-H is an effective cleaner because it lifts dirt and oil from surfaces and holds them in suspension so they can be wiped away. For flies and insects, this means they become more permeable. So they have (as we'll find out below) an aversion to the stuff. But unlike the chemical combinations produced by our modern-day industries, it's perfectly safe as it will break down over time.
And the most difficult thing about it is actually getting rid of it - because it comes in a highly concentrated form and very small amounts are used in cleaning.
In the recipes I've found for fly control, Basic H is usually used in much higher concentrations. But it will still last a long time.
