Q. Can I stop using preventatives in winter months, when all the fleas, ticks, and mosquitoes are dead?
DANA KOCH, VMD, MLAS
A. The best approach to flea and tick management is to use it all year, but depending on the region or area of the world you live in this can make a difference.
Fleas, eggs, larvae or pupae die if the temperature falls to 37°F for 10 days. Most fleas and ticks prefer to live in warmer climates, but even in cold weather they can find a way to survive. This survival may be accomplished by living on wild animals, or hiding in bedding, barns, sheds or under decks.
