I accepted a project to stop Iguana's from eating nice flower's from a location, next to 100 acre nature preserve. Yesterday I stop by after using general science the day before, did not see an Iguana for two hours. Then 2 small one's,I have been surprised that my efforts would pay off.There was a big T.V. story that may have been picked up cable news about a little girl kicking an Iguana and getting a nasty bite on the foot requiring 14 stiches. Some cities have given up ,the Iguana's have taken over.With the bite to the child thing's may change again. Dealing with this you have a 50-50 problem ,you don't know who are for or against you, so you have be low key. Do you live in an Iguana or fire ant area,would like to get reply.
