Pesticides are a rather excellent killing device to get rid of insects, however, once they are used they often have other side effects because the poisons enter the food chain.
You see, just because you poison one species in the food chain does not mean that the species that rely on them for food will stop eating them.
Thus, the species higher on the food chain get sick too, and have weaker offspring, and so on up the food chain.
  We hardly address this when getting rid of pests, as the poisons enter the food chain.
It is not an unknown problem, obviously biologists are working on such things all the time.
Perhaps you have considered this around your own home.
I noticed that when they spray for crickets, scorpions around here that the scorpions become so slow they are easy prey for the Road Runners, but was the road runners and frogs eat the crickets and scorpions they start moving slower and die too, it's unfortunate, folks do not see this.
  Indeed, I am a proponent of sound energy deterrents for crop perimeters, very worried about the bees.
One graduate student recently told me she is working on taste deterrents.
Taste is a brilliant idea.
Yes, that's huge, great idea, as every species has tastes that they do not like, usually they simulate their poisons.
She told me that taste aversion works but it is rather tough to test its on site.
  This makes sense, but taste aversion is a great concept and strategy, totally needed and especially wise for soft fruit like strawberries, where it's very dangerous to be pummeling with pesticides.
Soon, this graduate student will be doing a PhD project on taste aversion, this makes total sense, I'd love to read this dissertation when completed.
You see there are answers to our most pressing challenges of the day and luckily we have some bright students working on it as we speak.
Think on this.
