Description: | This image depicts 0.5% permethrin-treated cotton that had been bound in a chicken-wire netting. This would subsequently be collected by a rodent, and taken back to the animal’s burrow, thereby, killing fleas carried on the rodent, and within its burrow in order to curb the spread of bubonic plague organisms, Yersinia pestis, and Colorado tick fever virus. Techniques like the use of these baits are used to control the flea populations in and around human habitations, by using the flea’s primary hosts, the rodents, as the delivery mechanism for the insecticide intended to kill the flea disease vector, through whose bite, these diseases are spread. |
