We just bought a home that was built in 1986 and had a pest control guy come out to give us a price for a termite bond. He found no existing problems and had mentioned to me that he found it unusual for a 22 year old home in Georgia to not be under a bond, never have been treated for termites and yet shows no sign of any termite activity. The crawl space is also rather clean...no spiders or cobwebs, etc. He mentioned chloradane and suggested that perhaps it could have been used on our home given the lack of infestation after so long with no treatments. After doing some searching, I'm a little concerned about this chemical and the potential harm it could cause my wife and 7 month old son. I guess the question is, should I be worried? Is there any way to have the property tested? We've only been in the home for a few days now and so far, no illness or odd symptoms. If anyone has info or can point to some good resources for information, it would be a big help! Thanks!
