Brown Dog Tick Infestation: Complete Home and Pet Control Guide

Why Tampa’s Indoor Tick Problem Is Different

Moving from Gainesville to Tampa brought a sudden surge of tiny, pinhead-sized ticks on a dog. The culprit is almost certainly the brown dog tick (Rhipicephalus sanguineus), the only tick that completes its entire life cycle indoors.

Brown Dog Tick Biology

• Four stages: egg, 6-legged larva (“seed tick”), 8-legged nymph, adult.
• Mating on host; female drops off to lay 1,000–3,000 eggs in cracks/crevices.
• All stages can survive months without feeding.
• Prefers dogs; attaches to ears, between toes, along back.
• Indoors: behind baseboards, under moldings, in furniture, window pulleys.

Integrated Control Plan

1. House & Kennel Sanitation

• Vacuum thoroughly (dispose of bag immediately).
• Wash pet bedding in hot water.
• Steam-clean carpets and upholstery.

2. Indoor Insecticides

• Residual sprays: Bifen IT or Conquer (bifenthrin) applied to all cracks, crevices, baseboards, moldings, pet areas.
• Space sprays: Pyrethrin-based (Clear Zone) for quick knockdown; supplement residuals.
• Dusts: Drione (pet bedding) or Delta Dust (cracks/crevices).

3. Pet Treatment

• Frontline (fipronil) or permethrin-based spot-ons labeled for ticks.
• Treat all household pets simultaneously.

4. Outdoor Perimeter

• Bifen IT, Permethrin SFR, or Conquer applied to grassy/bushy areas near house, lawn edges, under porches.
• Drag a white cloth to survey tick density.
• Mow lawn, remove brush, fence against deer.

When to Call a Pro

Large, established infestations often require a licensed pest control operator with a guarantee. Brown dog ticks are notoriously difficult to eliminate without professional-grade equipment and persistence.
