The vet said to buy Knockout E.S. and treat my house after taking my cats to the vet for tapeworms. After reading the label, it almost sounds like you need to wear one of those contamination suits and leave the house for hours.

Anyone used this product and know how to use it properly? How much should be sprayed and how do you know when it's dry? Amazon.com reviews said it took hours and you needed all this safety gear. Or is there something safer and/or better?

Stupid fleas..and my cats are indoor. If my house is infested, my DH's legs would be a mess so I'm not sure it's as bad as my vet insists.
