Tried the garlic - fresh crushed garlic mixed with hamburger. Helped a little bit.
Sprayed the house and yard - helped a little bit.
Near me, I'm in a pretty urban area, but there are lots of stray cats spreading fleas all over the place.
Got the Advantage and Frontline (used both, they both work), no more fleas! Great stuff, these products are nothing like the stuff you can buy off the shelf at Wal Mart. They dry in the animals fur, so no oily fur.
If usinfg a product like this, the rest of the fleas in the environment will die off, as they no longer have a food source. It may take a while though.
As to flea bombs, the foggers, small cans that you place in water by Raid I think, are the only ones I've found that will reliably kill fleas.
For your yard, Ortho Max, good stuff! Kills bugs, but the active ingredient, Bifenthrin , is a heck of a lot more pleasant to use than Diazinon.
FYI - Diazinon is an organo-phosphorus based insectide, not terribly dissimilar to Nerve Gas. I still use it for my veggies, as the stuff works GREAT! Just be very very VERY careful about getting the stuff on you. It ain't good for ya!
