Cockroaches Are Becoming <br />More Resistant to Insecticides A new study from Purdue University says <br />german roaches are adapting to the substances. Even though roaches live no longer than<br />six months, they are still able to<br />evolve in order to survive obstacles. For testing, three roach colonies were <br />each sprayed with a different insecticide <br />that can be found in stores. The insecticides used in testing, which went on for over six months, were <br />also registered by the E.P.A. One colony was sprayed with <br />three insecticides, while the next <br />got two and the last received one. Researchers went on to find <br />that most of the roaches, even when <br />sprayed with multiple substances, did not die. The only chemical able to kill roaches<br />was abamectin gel bait.
