This will depend upon whom you want to talk to, and how much risk you are willing to accept in terms of flea and tick infestation.
The closer to the equator you get, the more likely you'll need to apply flea/tick preventive (such as Frontline) to your pets. This is because locations closer to the equator have less distinct temperature differences throughout the year, so it is more likely fleas and ticks will be active throughout the year.
Also, the more active your pet is outside, the more likely you'll need to apply Frontline throughout the year to prevent a flea or tick infestation. Even in the dead of winter, if you get a few warm days in a row some ticks may emerge and attach to your pet.
The company certainly recommends applying Frontline year-round. This boosts sales for them, as well as helps to protect against liability suits for treatment failure. It also takes into account the typical human behaviors of forgetting to do something when you take a break from it - a fair number of owners will intend to start applying Frontline again on March 1, but may not actually apply it until May 15 because they keep forgetting about it until they see a tick on their dog.
However, veterinarians in temperate zones may recommend only applying from the start of spring through the first hard freeze of the fall, unless the pet will be traveling to a warmer climate over the winter months.
The dog has to be at least 3 months old.
You can not apply frontline on a cut or bleeding blister no.
To prevent snow from blocking your front door during winter, you can shovel regularly, use a snowblower, apply salt or ice melt, and install a roof overhang or awning to prevent snow accumulation.
To prevent damage to a frozen bicycle during winter, store it indoors, use a bike cover, apply lubricant to moving parts, and avoid leaving it outside in extreme cold or wet conditions. Regular maintenance and cleaning can also help protect the bike from winter damage.
To prevent bronzing on boxwood plants in winter, provide adequate water, protect from harsh winds, and avoid excessive pruning. Apply a layer of mulch to insulate the roots and consider using anti-desiccant spray to protect against winter dehydration.
I worked for a Vet some years ago. Of course, Frontline's packaging says it is a ONE MONTH dose. And since the packaging notes that, then the Vet must tell the client that it is a one month dose and needs to be reapplied each month. However - the Vet told us technicians that it really works for up to 3 months! but if you live in an area where fleas are more prevalent, then you would want to apply every 6-8 weeks. I live on the Mid - East Coast. So in the winter I apply every 3 months, and in the spring-fall, every 6-8 weeks.
To prevent windows from leaking cold air in winter, you can use weatherstripping to seal gaps, apply caulk around the edges, install storm windows, and use insulating window treatments like thermal curtains or window film.

Frontline Combi for cats is effective in preventing and treating fleas and ticks. It provides long-lasting protection, is easy to apply, and is safe for cats. Using Frontline Combi can help keep your cat healthy and free from these pesky parasites.
It is recommended that you do not wash your dog for at least 48 hours after applying frontline. You should not use a harsh shampoo or a flea shampoo when you have used frontline. Washing your pet up to once a week was shown not to impact its effectiveness.
The reason that you need to apply frontline to the shoulder blades is so that dog or cat can't lick it. Putting it on your animal's stomach where he can lick it can be dangerous to the animal.
Frontline Plus, an anti tick medication for dogs and cats, should ideally be used once a month to twice a month based on the seasonal changes. (Some months ticks are more prominent than other months). If too much is used in one application, wash the area with proper care and reapply the proper amount. Make sure you apply the medication an area where the cat cannot reach. (Neck, back)
