What works for eliminating termites in my house?

assuming you mean for subterranean termites..what you can do to help would be make sure they aren't coming in from a faulty grade where the soil around the home is higher than the bottom of the veneer. Other than that, when you have it treated insist they use a product called Termidor. Stay away from the baits, way too much money for no more the results.

The methods differ between termite types and a host of other factors. They're sneaky little critters and it often takes a deal of knowledge to avoid making a right mess of things. The general answer is baiting for subterraneans and fumigation for drywoods (http://drdons.net/termite-control-methods ) but that mightn't be right for you. Find a competent inspector (http://drdons.net/content/choose ) and get a timber pest inspection done first. Then you'll know what your dealing with and have a good idea of the best/cheapest way to proceed.

Call a pro to do it. Termites can do a lot of damage if not treated correctly. If you do it your self use bait stations.
