Well only time will tell if these tactics will really work. Insect eggs are amazing durable. And it only takes a few survivors to start a new infestation. In the past such infestations were controlled with long-lasting insecticides like DDT and Cloroidain but just about all long-lasting insecticides have been banned as being carcinogenic or otherwise detrimental to the environment. This leave us with insecticides which have lost their potency by the time the eggs hatch. After battling recurrent flea infestations for years I just want to avoid any more such battles.
