We use inspection, supplemented by natural essential oil mixtures.
I try not to use insecticides on my dogs. We are in a heartworm area, so they are on preventive. Four on Heartguard, one on Interceptor.
I don't know why Hearguard is on the list for fleas and ticks - it's my understanding that ivermectin, the active ingredient in Heartguard, is not effective against fleas or ticks, and that the dosage for parasitic infestations for which it is effective would have to be higher anyway.
