Designed and trialled at Kandanga Farm by HRM graduates and Certified Organic cattle farmers, Tim & Amber Scott, the BOS BAG is a simple, chemical free and effective means of treating livestock with non-residual, powder fly control products. The refillable dustbag can be loaded with 4-5kg of Grainsave™ (an on-label insecticide grade fine-ground DE). This powder carries labels for insect management, has no WHP and no residual and has no effect on Dung Beetle populations. It’s a contact only insecticide made of a crushed rock then precision ground to <10 Microns (unlike fertiliser grade DE products of 100+ Microns).
Bos Bags have recently been refined to make them even more robust and when used with Grainsave, are a cost effective way to manage fly and other biting insects for less than 2c/hd/day (powder cost).
Animals self-medicate so usage rates vary but generally one bag will be needed per 50-60 animals and one refill lasts about a month. Anecdotally however, in time-controlled, high density grazing scenarios, less bags are needed due to the lower required coverage to still achieve insect contact.
Use as part of an integrated approach to parasite management with Bos Lik (or other Sulphur + Allicin nutritional supplements), breed/animal selection, grazing management, traps, dung-beetle populaton enhancing management practices (getting rid of systemic chemicals) and other measures that break insect breeding cycles and build natural resellience.
*Grainsave is an NOP Organically Certified input. Bos Lik is Australian Organic Certified.

BOS BAG installation:
1. When you get your BOS BAG you will need to find a wood or steel horizontal support pole no shorter than about 120cm to slot through the top "folded" end of the bag. Make sure you insert through the middle of the two layers of hessian and the canvas outer. Screw or tie the bag at each end to the pole to ensure bunching doesn’t occur. Pole diameter may be up to 40 or 50mm and the pole will only have to be able to support 10kg plus the extra pressure of cattle "playing" with the suspended bag.
2. Lengths of chain, cable or rope long enough to allow horizontal hanging at the desired application height should be attached to each end of the pole. Remember to re-fill the BOS BAG you will have to be able to easily take the bag down, re-fill and replace.
3. The canvas BOS BAG has eyelets that provide an alternative attachment option however it is recommended that the eyelets be used IN ADDITION to the horizontal support pole.
4. To fill the BOS BAG, open the Velcro end and, using a scoop, pour approximately 1/3 the powder bag contents carefully into the opening. Try not to get dust into the Velcro as it will affect performance of the Velcro. Don’t overfill.
5. Hang the bag in a high traffic area of the paddock with its base height a few inches below the height of the shoulder of the smallest target animals. If you are feeding lick (such as sulphur) for an integrated approach to parasite control, you may choose to place bag over lick feeding area, near entries to water or at a high-traffic shade camp area.
6. After a week, usually most animals know what the bag is for and an effect should be seen. Move the bag with the cattle if necessary and over time the cattle will seek out the bags so placement becomes less important. Dust use by bulls is usually much higher than other classes of cattle.
