Baits contain insect or rodent poisons mixed with food or
other attractant. The principal behind most baits is that the pest will
take some of the food containing the pesticide, and bring it back to the
other members of its colony.
Volatile chemicals, like chlorpyrifos, used as the poison in
baits puts human health and the environment at risk. A large concern is
the volatility of the chemicals and its ability to vaporize or volatize
into the ambient air and therefore expose people to the chemical. A bait
containing a non-volatizing pesticide, like boric acid, is just as, if not
more, effective in controlling the pest population and doesn’t pose the
high risk for exposure.
Baits, by their very nature, are a better choice for pest
control than sprays or broadcast applications. It is extremely important
that baits be made of tamper resistant containers or for crack and crevice
treatment, and be out of the reach of children.
