I like the yard spray. It knocks down mosquitoes and fleas, and I never see a tick in our yard. HOWEVER...you have to spray weekly, and it's washed away by rain. Right after spraying, the yard smells like a cedar closet (but the mosquitoes are temporarily gone). If you keep up with weekly yard spraying for at least a month (or even two), I think you'll get control of any fleas that are outside. With mosquitoes, you also need to use something like Mosquito Bits or Dunks in any standing water sources and catch basins monthly (these products are supposed to be non-toxic for aquatic life if they wash into streams, but they keep the mosquitoes from breeding).
As for the Wondercide dog spray, when we hike in places with lots of tall grass where ticks are likely to be in the West, I sometimes use it as a repellent in addition to their monthly RX meds so that we don't bring home any hitchhikers that haven't died by biting the dog yet. My dog HATES the smell and clucks at me when I'm rubbing it on, but I haven't seen a tick on him this year, even though my neighbors keep saying they're seeing them around the hiking trails. We're using Simparica (RX-only, oral med) for the summer while we're in tick-country to be sure he's safe though -- the risk of tick-borne illness is just too high for me to trust to essential oil.
The best product Wondercide makes is their shampoo bar for dogs. It has neem and other oils in it, and it's the easiest bath you'll ever give because of the bar shape -- I was astonished how much faster it was to bathe a dog. It smells wonderful and rinses easily.
