That "twister" tool does work. I would be interested to know what the yard can be sprayed with to control ticks. I used to think the dogs brought them back only from venturing out into the brush but they have only been in the yard the last week or so and have found 2 ticks. We apply Advantix monthly but still am picking them off and even find them on the floor once in awhile. Wondering if the collars work any better or maybe change to another topical drug?
