How to Keep Bugs Off Your Dog Naturally This Summer

Summer means longer walks, backyard hangouts, and outdoor adventures with your dog. It also means bugs. Mosquitoes, gnats, flies, and fleas don't care how much you love your dog — they're coming for them anyway.

The instinct is to reach for the strongest repellent you can find. But most conventional bug sprays contain DEET, permethrin, or other synthetic chemicals that can be harmful to dogs — especially when they groom themselves and ingest whatever's on their coat. There's a better way.

Here's everything you need to know about keeping bugs off your dog naturally this summer.

Why You Should Avoid DEET and Synthetic Pesticides on Dogs

DEET (N,N-diethyl-meta-toluamide) is the active ingredient in most human bug sprays and is toxic to dogs. Even small amounts can cause neurological symptoms including tremors, seizures, and disorientation. Permethrin — common in tick sprays — is highly toxic to cats and should be used with extreme caution around dogs.

The problem is compounded by the fact that dogs lick themselves constantly. Whatever goes on their coat goes in their mouth. That's why choosing a natural, non-toxic bug repellent isn't just a preference — it's a safety decision.

Natural Ingredients That Repel Bugs

Several essential oils have well-documented insect-repelling properties and are safe for use on dogs when properly diluted:

• Citronella — one of the most effective natural mosquito repellents, widely used in outdoor candles and sprays
• Lemongrass — contains citral and geraniol, compounds that deter mosquitoes and flies
• Cedarwood — repels mosquitoes, ticks, and fleas; also has a calming effect on dogs
• Peppermint — deters flies, fleas, and spiders; provides a cooling sensation
• Geranium — shown to repel ticks in several studies; pleasant floral scent
• Rosemary — natural flea deterrent; safe for dogs and commonly used in natural grooming products
• Wintergreen — adds additional insect-deterring properties when combined with other oils

The key is proper formulation. Essential oils should never be applied undiluted directly to a dog's skin — they need to be suspended in a carrier like water, glycerin, or a gentle surfactant to be safe and effective.

How to Use Natural Bug Spray on Your Dog

Using a pre-formulated natural dog bug spray is the safest and most convenient approach. Look for products that:

• Are specifically formulated for dogs (not humans)
• Use properly diluted essential oils in a water or glycerin base
• Are free from DEET, permethrin, and synthetic fragrances
• Have clear ingredient lists with no hidden chemicals

When applying, spray lightly over your dog's coat — focusing on the back, sides, and legs. Avoid the face, eyes, nose, and mouth. Apply 5–10 minutes before heading outside and reapply as needed during extended outdoor time.

Other Natural Ways to Reduce Bug Exposure

Bug spray is one layer of protection. Here are a few more habits that help:

• Avoid peak bug hours — mosquitoes are most active at dawn and dusk. Schedule walks for mid-morning or late afternoon when possible.
• Stay away from standing water — mosquitoes breed in still water. Avoid ponds, puddles, and marshy areas on walks.
• Keep your yard maintained — tall grass and dense vegetation harbor ticks and fleas. Regular mowing and trimming reduces habitat.
• Check for ticks after every outdoor session — run your fingers through your dog's coat, paying special attention to ears, armpits, groin, and between toes.
• Wash bedding regularly — fleas can live in fabric. Washing your dog's bedding weekly in hot water helps break the flea life cycle.
• Consider a natural flea comb — a fine-toothed flea comb used after walks can catch fleas before they establish.

A Note on Ticks and Fleas

Natural bug sprays are a helpful deterrent but are not a substitute for veterinary-recommended flea and tick prevention in high-risk areas. If you live in a region with high tick populations or your dog has had flea infestations, talk to your vet about a comprehensive prevention plan. Natural and conventional approaches can often be used together.

The Bottom Line

Keeping bugs off your dog doesn't have to mean exposing them to harsh chemicals. A well-formulated natural bug spray using citronella, lemongrass, cedarwood, and other proven essential oils can provide meaningful protection — safely, sustainably, and without the risk of toxicity from licking.

This summer, make the switch to natural. Your dog will thank you — and so will the environment.
