Remember that icky feeling you get when you see a cockroach? Odds are that you will have to bear with it more often than you expected as cockroaches are now developing cross resistance to multiple types of pesticides
Cockroaches have become harder to kill and could soon be “almost impossible” to control using pesticides alone, according to a study funded by the United States housing department.
Researchers from Purdue University in Indiana spent six months trying to eradicate German cockroaches (Blattella germanica L.), one of the most common species of household cockroach in the US, Australia and Europe, from three low-rise apartment buildings in Illinois and Indiana.
Subsequent laboratory tests showed that cockroaches were able to develop a “cross resistance” to multiple types of pesticide, meaning that those which survived the spraying would go on to survive other eradication attempts even if a different class of pesticide was used.
Over time, as more and more cockroaches become resistant to pesticides, we can expect these pests to become a very difficult problem to control. Read more about this horrific news over at The Guardian.
