Hey I have purchased this and have great results!
(diatomaceous earth) because this is natural I still deworm using Panacur (twice) but I find it helps allot... The only downside is the amount of time it has to be given (1 month) BUT! I got a 25 kilogram bag for 41$ (CAD)! It's a white powder... You mix some with food or water... It kills EVERYTING EXCEPT FOR THE DOG ITSELF!!!
you can put the powder on the body to kill fleas ear mites ticks ect... Put it in their food to kill worms (dewormer) you can also put it outside or inside anywhere will kill all bugs! Ants, fly's ect....
Amazing that this product is not more popular... It's the safe insecticide which can be eaten with no poisoning! Will also kill earwigs (ANY BUG!)...
this product is mostly used by farmers for cattle, but it is effective with dogs and cats as well...
Here is a link for more information!
