Then you are not using enough or using it properly.I can
assure you it works very well,and l have kept chickens 40 +
yrs.When it came along we stopped losing birds by 70 %.
As we know Red Mite is not red until it has fed.I have always used Diatomus Earth
on birds,in nest in coop,in food because they get in there as well.It took a Cockerel to
shoe me that buy turning food over.We also mix a solution of it with water so it is like
paint,and rub in...
