400 ml in the value size: when XXL makes sense

The 400 ml XXL bottle contains the same plant-based formula as the 100 ml variant: ten active plant-based ingredients with thiamine as the cornerstone, combined with manuka oil, neem extract, geraniol, eugenol and other essential oils. The efficacy against ticks and other parasites is identical to the smaller variant.

The only difference is the bottle size. At 400 ml instead of 100 ml, the price per ml is significantly lower. If you use FlyBlock regularly, supply multiple dogs or have a large dog, the value size is the smarter choice.

When the 400 ml value size makes sense

NutraVital® FlyBlock is available in two sizes with an identical formula. The XXL variant with 400 ml is particularly worthwhile if you use the spray frequently or for multiple dogs. Here are four scenarios where the larger bottle is the more economical choice.

For year-round use

If you use FlyBlock consistently throughout the year, you'll be spraying every 2 to 3 days during the season and every 7 to 14 days outside it. Over the course of a year, that adds up to a lot of applications ... and that's where the value size really pays off. With a 400 ml bottle, you have enough supply to comfortably last the season without having to reorder mid-way through tick season.

For multi-dog owners

If you have two, three or more dogs in the household, you'll naturally use more spray per season. The XXL bottle lasts for significantly more applications than four individual 100 ml bottles, without the hassle of reordering multiple times.

For large dog breeds

With a Bernese Mountain Dog, Labrador or Great Dane, considerably more spray is needed per application than with a Dachshund or Yorkshire Terrier. More coat to cover, more spray needed. The 400 ml bottle is the more economical choice for larger breeds.

For extensive environmental use

FlyBlock isn't just for your dog's coat: it's also suitable for dog houses, sleeping areas, transport boxes and carpets. If you regularly treat the environment as well, you'll use additional product. The XXL bottle comfortably covers both areas of use.

When to use the anti-parasitic spray for dogs

  • To prevent parasite infestation in dogs with access to forests, meadows and gardens

  • To repel ticks, fleas, mosquitoes, sand flies and lice

  • For environmental treatment of kennels, transport boxes, sleeping areas and carpets

  • Year-round as a baseline protection, with increased use during tick and flea season

  • Suitable for dogs of all ages, including young dogs

  • As a natural alternative to chemical spot-on products and collars

How to use FlyBlock XXL

Shake the bottle well before use. Spray from approximately 20 cm distance onto the coat, including against the direction of the fur. Treat the belly, legs, back and neck, but avoid the face: instead, apply a few sprays to your hand and rub in.

During the active tick season from spring to autumn, apply every 2 to 3 days. Year-round, use every 7 to 14 days as a baseline protection. Reapply after bathing. Protect from direct sunlight.

For environmental use, spray dog houses, transport boxes, blankets, carpets and sleeping areas directly.

FAQ – Frequently asked questions about the 400 ml value size

Here are the questions we're asked most often about the XXL product.

Yes. Both bottles contain the same plant-based formula with ten active ingredients. Efficacy, application and active ingredient profile are unchanged.
How long it lasts depends on your dog's size, how often you apply it and whether you treat only your dog or the environment as well. With regular use, the XXL bottle covers an entire season or more.
Like the 100 ml variant, FlyBlock XXL is suitable for all dog breeds and ages, including young dogs. If your dog has known allergies to any of the ingredients, consult your vet beforehand.
