Jane from San Francisco, Ca writes
I am using diatomaceous earth to kill fleas in my house, it will not kill flea eggs. Ii read that I need an IGR product to kill the eggs. will this product do the job?
Precor IGR Concentrate does not actually kill anything and will not kill any flea eggs. It will prevent the young that hatch out of the eggs from developing into reproducing adults. Precor can be used but we would also recommend using an insecticide spray instead of just diatomaceous earth to get faster results. We have a great guide here that can explain the best treatment for fleas.
