    Very good product

    By Jason on 02/14/2021

    This stuff is devastating to roaches. I just started using it (it's pretty new) and when I rotate it with another product the roaches don't stand a chance. Don't forget to use Gentrol with your applications.

Can Fipronil - Plus - C be applied in apartment kitchens and bathrooms for roach control if applied using a pin stream spray pattern?

Fipronil - Plus - C can be used indoors for roaches however per the product label, for German cockroaches applications must be directly sprayed within the void to be killed. This product cannot be sprayed around the perimeters inside, along baseboards, behind appliances, under sinks, etc. We would recommend using one of our Roach Control Kits for a complete treatment program using a residual insecticide, roach bait gel and insect growth regulator. Take a moment to view our How to Get Rid of Roaches Treatment Guide for step by instructions.

Does this kill termites
Fipronil - Plus - C is not labeled for termite control. I'd recommend taking a look at Taurus SC Termiticide

Unfortunately, we are not provided with all the reasons behind the restrictions or exclusions on a label. You can call the manufacturer of Fipronil-Plus-C at  480-357-8500. Other fipronil products can be applied as an exterior perimeter treatment for carpenter ants, such as Termidor SC.
