The problem with pests became more apparent around the same time as agriculture took off. Roughly 8000BC saw the effects of what pests could deliver to crops. Pests of which mainly insects destroyed crops where no preventative measures were taken. Crop rotation and moving was the only measures taken. Not up until the 1500’s did pest control as a trade really take off. Up until this the Egyptians and then Romans did use some types of insecticidal compounds in poisonous plants mixed within the crops but with no great effects. The voyages of Christopher Columbus led to the exchange of animals and plants and with these pest insects which needed to be controlled. Along with this the western world learned how to use predatory species from the origin of the pest insects. The western world also learned new preventative measures from the native Indians in like powdered seeds from a Lilly. They took these ideas and expanded on them. A host of inorganic chemicals were prepared and sold for the agricultural industry and were later replaced by modern chemical pesticides like DDT which only effect pest insects. pest control
Pest control diversified in other ways including preventing the spread of diseases like rats which carried the plague by transporting fleas with deadly diseases. Pest control took the form of educating the public on simple things like storing refuse, as well as rat poisons to control the increasing rat population. The way forward was debated, with good sanitation argued as a more ethical response to extermination of rodents. Rat poisons still remain legal today though, but improvements in sanitation have dramatically improved the spread of diseases. The moral ethics involved in pest control have played a part in the modern pest control trade. More emphasis is now put on relocating pests and preventative measures, rather than extermination, like temperature and controlling environments like damp rooms.
Research in to pest control is ongoing. It’s estimated that 42% of the worlds foods supply is wasted due to pests destroying agricultural crops. Add to this the damage caused from weather and other external factors, food dispersion can be greatly improved. Pest control looks set to be a problem for society into the foreseeable future. More education is still needed for the prevention of domestic and commercial pest problems like controlling environments that pests thrive on. Time to learn and implement these factors is a problem in the hectic modern day and will be in the future so pest control experts will need to be on call for some time yet.
