Frequently Asked Questions

Q1: How long does Virbac Knockout Area Treatment provide flea control after application?

Ans: Virbac Knockout provides continuous flea control for 120 days (4 months) with a single application. The NYLAR insect growth regulator prevents flea larvae from developing into egg-laying adults throughout this period, breaking the flea reproduction cycle effectively.

Q2: Can Virbac Knockout be applied directly to pets or their bedding safely?

Ans: Never apply Knockout directly to pets. However, you can treat pet bedding, carpets where pets rest, and upholstered furniture. Use a separate EPA-registered flea control product designed for direct pet application alongside this environmental treatment for comprehensive control.

Q3: What preparation is needed before applying Virbac Knockout to indoor areas?

Ans: Remove all pets, birds, and cover fish aquariums before application. Vacuum carpets and upholstery thoroughly, seal and dispose of vacuum bags outdoors. Cover food, dishes, and preparation surfaces. Ensure adequate ventilation during and after application.

Q4: How much area does one 14-oz can of Virbac Knockout cover?

Ans: One 14-oz can covers up to 2,000 square feet when applied as a fine mist. For heavy infestations, coverage may be reduced as more product is needed per square foot for effective control of established populations.

Q5: Is Virbac Knockout safe to use around children and pets after drying?

Ans: Yes, once completely dry and the area is thoroughly ventilated, treated surfaces are safe for normal contact. However, keep all people and pets away during application and until sprays have dried completely, typically 2-4 hours depending on ventilation conditions.
