Imidichlorprid is more of a systemic, and while it will give good results, it may not provide 100% control. Merit 75 is the only product that we sell that would contain the EPA registration to use indoors - http://www.epestsupply.com/product/BA...
Other than that, have you tried a straight pyrethrum product such as Riptide? Normally, Pyrethrum gives good results on whiteflies, it just needs regular applications. Also a good IGR such as Nyguard is recommended.
