I've been spraying my property monthly with this and it seems to be working well. I still see scorpions on my cinder block walls lining my property, but as long as I use Bifen XTS with a 4ft perimeter around my home's foundation, I maybe only see 1 a month inside. Should I add granules to my outdoor pesticide regimen or should I use something like Bifen IT indoors instead? As a side note, when I don't spray Bifen XTS monthly over the summer, I'll usually see 1 to 2 scorpions a week indoors.
You can use granules in the yard to help with scorpions food source or Bifen IT inside as a second layer of protection in addition to the Bifen XTS outside, though you could just use the XTS inside in cracks and crevices instead. XTS should be applied once a month outside and if inside once every 90 days. We do also have a great guides here for treatment of scorpions.
