The DeWormer doesn't taste bad at all. I drink it straight from the bottle. Kids, just put it in some juice or water. Don't even have to tell them what it is.
Pets, don't have a clue. Put it on their food I guess.
Maintenance. A big variable. Some say twice a month if not ill or have had any previous infestations. Others say every three days. If you don't live on a farm or visit the tropics you're pretty safe. There's a lot of hype out there about how easily you're supposed to be able to get infested but the research with plants indicates the bugs stay away from healthy stuff. Just watch the chemicals, wash you fruit and veggies good and you'll do fine.
