Not a miracle cure

by Jacob Clark -

It helped reduce the flea count but I still needed a more long term treatment. It's a good initial step though. Easy enough to apply

Effective and fast acting

I saw dead fleas almost immediately. It's a great initial blast to deal with a sudden outbreak. The smell is not too strong which is a bonus
