I`ve used frontline on my rottweiler and it doesn`t work. flea collars are useless on him got some new stuff and it doesn`t work either.
my yard is an acre that used to be a prarie. think I`ll try the sevin dust next time. not supposed to do anything for 36 days w/ this new stuff that already don`t work. SUCKS TO SEE HIM SCRATCHING ALL THE TIME!:thumbdow:
I agree flea collars are useless. But there is stuff you can do in addition to the new stuff your trying.
Fleas are more difficult (I think) because they can go dormant for long periods of time in several stages of their life cycle. IIRC, Frontline lasts about 4 weeks on the dog and is good for about 90% flea kill while Advantage is about 3 weeks with 99% kill but then drops the fourth week. If the problem is real bad, then the perscription stuff may be needed.
BUT the point is dormant ones are still around to emerge when conditions become favorable to them. Also, what they don't often state is that these two topicals don't stop the fleas from biting. So, the topical alones will not solve the problem. In addition to killing the fleas that get on your pets, in a bad situation (and it doesn't take much time to become that) you need to do a more comprehensive approach.
One trick I like is using a flea trap to locate 'hot spots' and kill a bunch while at it.
I use a gooseneck lamp but any other heat source wil do. Place it over a cookie sheet or pizza tin with a 1/4" of water and drop of detergent. Put this in differnt locations where the buggers may be attacking from. I'll leave the traps set up until no more fleas show up in the water. It won't get 'em all, but will identify the locations of the biggest problems.
The reason it won't get them all is twofold. One is that it only attracks adults. The second is fleas can move around, and some fleas - especially if desperate will latch onto less prefered hosts.
Inside I've used chemicals that stop the growth of the immature fleas (when the pets are not around) on things that aren't washable. Outside, I use diatamaceous earth - the version that is rough ground so it teats up the bodies of soft insects.
Whatever you do, you have to keep it up until all the eggs laid and all the developing ones are dead or can't reproduce.
Again, the extension office and state Ag schools often have good info.
The following bulletins have good information on which you can base a strategy. The Florida one particularly how the various chemicals work, so you can figure out how to combine them effectively with other methods of control.
