A cold compress and 1% hydrocortisone cream will handle most bug bites. For anything beyond mild irritation, you have a range of options from drugstore products to pantry staples, and the best choice depends on whether your main problem is itching, swelling, or pain.
Start With a Cold Compress
Ice or a cold pack is the simplest first step. It constricts blood vessels near the bite, which reduces swelling and temporarily dulls the itch. Wrap ice in a cloth rather than placing it directly on skin, and apply it in 10- to 15-minute intervals. This works for virtually every type of bite or sting, from mosquitoes to fire ants.
Hydrocortisone Cream for Persistent Itch
Over-the-counter hydrocortisone cream at 1% concentration is the go-to for bites that stay itchy beyond the first hour. It works by dialing down your skin’s inflammatory response, the process that causes redness, swelling, and that maddening urge to scratch. Apply a thin layer once or twice a day directly to the bite.
Keep use to 7 days or less. Children under 10 should only use hydrocortisone if a doctor or pharmacist recommends it. If a bite is still bothering you after a week, that’s worth a pharmacy visit rather than just reapplying cream.
Antihistamines for Widespread Itching
When you have multiple bites or the itch is keeping you awake, an oral antihistamine can help from the inside out. Cetirizine, loratadine, and fexofenadine are all available without a prescription and reduce the histamine reaction your body mounts in response to insect saliva or venom. These are especially useful for mosquito bites, which trigger a strong histamine-driven itch. A single daily dose covers you for 24 hours, making them practical if you’re dealing with bites over several days.
Numbing Products for Painful Bites
Some bites hurt more than they itch, particularly from fire ants, wasps, or horseflies. Topical anesthetics containing benzocaine (up to 20%) or pramoxine (1%) numb the area on contact. These come as sprays, gels, and creams. Products with menthol or camphor at low concentrations (around 0.5%) create a cooling sensation that also distracts from pain. You can reapply these several times a day for quick relief.
Calamine Lotion
Calamine lotion contains zinc oxide, which forms a protective layer over the bite and creates a mild cooling effect as it dries. The iron oxide in the formula gives it that familiar pink color. It works best for bites that are mildly itchy and slightly inflamed, like typical mosquito or chigger bites. It’s gentle enough for young children and can be reapplied as needed throughout the day. Calamine won’t do much for deep swelling or intense pain, but for garden-variety itchy bites, it’s a solid option.
Home Remedies That Actually Work
A baking soda paste is one of the most widely recommended home treatments. The CDC suggests mixing 1 tablespoon of baking soda with just enough water to form a paste, then applying it to the bite for about 10 minutes before washing it off. The alkaline mixture helps neutralize some of the itch-causing compounds in the skin.
Colloidal oatmeal, the finely ground oatmeal found in products like Aveeno, reduces inflammation by calming overactive immune signaling in skin cells. It also helps restore the skin’s protective barrier by boosting production of natural moisturizing fats. You can add it to a lukewarm bath if you’re covered in bites, or apply an oatmeal-based lotion directly to individual spots.
Aloe vera gel provides a cooling effect and mild anti-inflammatory action. Honey has some antibacterial properties that may help if you’ve scratched a bite open. Neither is as potent as hydrocortisone, but they’re safe, gentle alternatives when that’s all you have on hand.
Matching Treatment to Your Bite
Dermatologists generally recommend a “therapeutic ladder” approach. For mild, annoying bites, start with a cooling agent like menthol or camphor, or a numbing product with pramoxine. If the itch persists, step up to hydrocortisone cream once a day. For bites that swell significantly or cluster together, add an oral antihistamine. Stings from bees or wasps benefit from ice first, then a combination of pain relief and anti-itch treatment.
For any sting where the stinger is still embedded in the skin, scrape it out with a flat edge like a credit card before applying anything topical. Squeezing it with tweezers can push more venom into the skin.
Signs a Bite Needs More Than Home Treatment
Most bites resolve on their own within a few days. But some develop secondary infections, especially if you’ve been scratching. Watch for skin that feels hot to the touch, increasing pain rather than decreasing pain over time, visible swelling that keeps spreading, or pus or fluid draining from the bite. These signs point to infection and need professional treatment.
A severe allergic reaction is a separate concern entirely. Sudden swelling of the lips, mouth, or throat, difficulty breathing, wheezing, feeling of throat tightness, or skin turning pale or blue are all emergency signs. Feeling suddenly confused, very dizzy, or losing consciousness also qualifies. This type of reaction requires immediate emergency care, not topical treatment.
