1.1M views · 33K reactions | NATURAL PEST CONTROL⬇️ Let’s call these “preventatives” what they really are: pesticides. Read the fine print, it’s all right there. These chemicals are designed to eliminate, yet people willingly pour them on their dog’s necks or feed them like candy every month. Cats too… Read the stories. Thousands of ☠️ a year, and the products are still on the shelves 🥴 The real key to keeping animals free of pests isn’t poison…it’s health. A strong, nourished body naturally resists invaders. But when pets are eating kibble full of dyes, corn fillers, and by-products, they’re already compromised… and then the “solution” they’re sold is more chemicals. See the cycle? Here’s what I actually use to keep my dogs pest-free year-round, straight from nature: Coconut oil – Smothers fleas on contact and soothes dry skin. I feed about 1/4 tsp per 10–15 lbs of body weight a few times a week, and rub it into their coat as needed. Always start small to avoid tummy upset. Pumpkin seeds – Raw and freshly ground. They contain cucurbitacin, which helps paralyze worms so the body can expel them. I give 1/4 tsp per 10 lbs of body weight with meals during pest season. Brewer’s yeast – Packed with B vitamins, it changes your dog’s scent just enough that fleas hate it. I use 1/2 tsp for small dogs, 1 tsp for medium dogs, and up to 1 tbsp for large dogs mixed into food a few times a week. Garlic – When used properly, it’s a powerful repellent. The sulfur compounds released through the skin drive off fleas, ticks, and mosquitoes. I give 1/4 clove for small dogs, 1/2 clove for medium, and up to 1 clove for large dogs, 2–3 times a week. Always watch for sensitivities. Diatomaceous earth – A natural powder that can be dusted onto fur (avoiding eyes, nose, and ears). It eliminates pests externally without chemicals. Apple cider vinegar – Just 1 tsp per 50 lbs added to drinking water a couple times a week. Always keep a second bowl of plain water available. Unlike the chemical cocktails sold at the office, they don’t come with a long list of side effects. I’ll choose nature over poison any day.
