Since our 3 dogs are living inside the house, it is imperative that they are cleared of parasites. But recently, we have been finding ticks in their coat, one or 2. But this past week, there is already an infestation since the ticks number more than 10 in just one dog. We left the house and had it sprayed with insecticide. For the exterior, we used water with liquid dish washing soap. That was last Monday. Yesterday, Tuesday, there was 1 tick found and the other dog had 2. We are still in the process of observing. \n\nBy the way, our dogs are armed with Frontline, the spray on the coat that lasts for weeks to repel the ticks... but is not effective at all.
