The cards I found close to useless. The tools in the link from the parent poster, which are actually for pets, work much, much better.

And tiny ones are easy to remove with finger nails and some spit. But it requires some skill, do not stress out the ticks while they are attached and be careful to not partially remove it.

(Just had to remove 3 ticks on me I failed to spot after a late night walk yesterday, bigger and medium sized ones with tool, the small one with fingernail)

edit: and found a 4th one, but a tiny one(nymphe), they don't carry lyme disease as only ticks who have previously bitten a infected animal before will have it

In my experience it works the same way by simply using a drop of dishwashing detergent on them. After 30 seconds max they want to get out with wriggling legs. Works on me after jogging, on my cats, at the back of their neck. Any other place they can take care by themselves, and do.

On dogs my friend likes to strike a match, touch the extinguished tip to the back of the tick, and then pull it out with tweezers. Seems to work
