Drops and a flea collar are not helping, what should I do? - briefly
Obtain a veterinary evaluation to confirm the infestation and receive a prescription medication regimen, such as oral ivermectin or a stronger topical agent. Simultaneously treat the home environment with an approved insecticide and wash all bedding to prevent reinfestation.
Drops and a flea collar are not helping, what should I do? - in detail
When topical medication and a collar do not eliminate the infestation, the first action is to verify the correct application. Check the dosage, the specific product’s species suitability, and the interval since the last treatment. If any of these factors are off, re‑apply according to the label or replace with a product that matches the pet’s weight and age.
Next, schedule a veterinary examination. The veterinarian can identify resistant flea strains, allergic reactions, or secondary skin conditions that interfere with treatment efficacy. A prescription oral adulticide, such as a fast‑acting isoxazoline, may be recommended, often combined with a short‑term oral larvicide to break the life cycle.
Environmental control must accompany medication. Perform the following steps:
- Wash all bedding, blankets, and removable covers in hot water (minimum 130 °F) and dry on high heat.
- Vacuum carpets, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately.
- Apply a residual insecticide spray or fogger to floors, cracks, and baseboards, following label instructions for safety and coverage.
- Treat the yard with a pet‑safe outdoor flea spray, focusing on shaded, humid areas where larvae thrive.
- Use flea traps or sticky boards to monitor ongoing activity.
If resistance is suspected, rotate to a different class of products after a minimum of two weeks to avoid cross‑resistance. Maintain the chosen regimen for at least six weeks, the period required for the flea life cycle to complete, even if adult counts appear low.
Finally, prevent re‑infestation by implementing a year‑round preventive program. Options include monthly oral preventives, long‑acting spot‑on treatments, or a combination of both, administered consistently on the schedule prescribed by the veterinarian. Regular health checks will confirm that the chosen strategy remains effective and adjust it as needed.
