Hopefully this kind of question hasn't been asked to death here but I'm looking at two companies that provide treatment in my area and the cost difference is astounding to me.

Company #1 uses Fipronil and fogs the yard. Charges $40 first time and $80 each time after that. Guarantees a month each treatment.

Company #2 uses Cyzmic CS and sprays the yard with micro encapsulated product. Charges $215 each time and says it should last 30 days or so as well.

Any lawncare pros out there that could shed some light on which option would be the better route?

I should mention as well I have two small children and a dog that likes to spend time outside so if theres any health concerns I should be aware of as well please let me know!
