>>> Where did you get the dry neem and what type of yarrow? Did you put it on the dog's fur?I've found essential oils work okay, citronella in particular but not great.
Here's a tick powder I make that actually works equally well with mosqitoes, you can apply it weekly/biweekly. You can even spread if around the house.
1 part diatomaceous earth (burns and dehydrates mosquitoes, they should fly off after touching it)
1 part dry neem (strongly repels)
1 part yarrow (repels)
