Supervisors Monday debated whether such spraying does more harm than good.
District 5 supervisor Ray Boswell charged that the insecticide being used, not only killed mosquitoes but also what he called 'good insects' such as bees, butterflies, worms and others.
"And I'm not sure that's legal for us to do that, and if I were a beekeeper, a honey raiser, I would have certainly have some strong concerns about this because I think this board's going to have some strong liability for it," said Boswell.
County engineer Neal Carson verified the spray is not selective.
"All these insecticides are going to kill bees, moths, butterflies, larvae egg insects, if they get enough penetration of the chemicals on them," Carson said. "Of course, it does kill mosquitoes, they being the smallest of the insects, it kills better than it does the rest of them but it does kill them all if they get a dose of it."
"As you mention, these insects may be exterminated," said Smith. "Also the other side of the coin is that we need to be spraying, because you have West Nile virus and that's one reason that we've been spraying."
At that point, supervisors agreed to limit spraying, for the time being, to areas around baseball fields, schools and area parks until more information is known.
