| 🔑 Key Takeaways |
| Baking soda paste is an effective, readily available home remedy to provide soothing relief for a mosquito bite’s intense itching. As a mild alkaline substance, the paste can help neutralize some of the acidic compounds in the mosquito’s saliva and cool the inflamed skin. While it offers immediate comfort, baking soda paste does not suppress the underlying inflammation as effectively as topical steroids like Hydrocortisone. It is best used as a first-line soothing treatment or when medical creams are unavailable. |
How Baking Soda Paste Works
Baking soda (sodium bicarbonate) is a common household item that acts as a mild antacid and drying agent, offering relief for many minor skin irritations.
| Mechanism | Effect on Mosquito Bite | Rationale |
| pH Neutralization | Mosquito saliva contains acidic components. Baking soda (alkaline) may help neutralize these irritants on the skin’s surface. | This theory is debated by scientists but remains a persistent, effective folk remedy for immediate soothing. |
| Drying Agent | When the paste dries on the skin, it helps reduce moisture and inflammation. | This physical drying action can help calm the irritated skin surface. |
| Cooling | The evaporation of water from the paste provides a cooling sensation that temporarily numbs the itch receptors. | Provides instant comfort, similar to a cool compress. |
2. Step by Step Application Protocol
Baking soda paste is simple and safe to use on intact skin.
- Preparation: Mix 3 parts baking soda with 1 part water (a few drops) to form a thick, oatmeal-like paste.
- Application: Apply a generous, thick dollop of the paste directly onto the mosquito bite.
- Duration: Allow the paste to sit and dry on the bite for 10 to 15 minutes or until the itching subsides.
- Rinse: Gently rinse the area clean with cool water. Reapply as needed for recurrent itching.
Combination Strategy
For best results, baking soda paste can be used for immediate soothing, and then a more effective anti-inflammatory cream can be applied:
- Cooling: Use the paste first to calm the initial intense itch.
- Long-Term Relief: Apply 1% Hydrocortisone Cream to the bite after rinsing off the paste to suppress the underlying inflammation.
3. Safety and Cautions
| Warning | Rationale |
| Do Not Scratch | Even with the paste on, avoid scratching, as this can break the skin, making the area vulnerable to secondary bacterial infection. |
| Do Not Use on Broken Skin | Avoid applying the paste to open wounds, scratches, or areas of severe blistering, as it can cause further irritation or pain. |
| Seek Medical Care | If the bite swells severely, is accompanied by fever, or shows signs of infection (pus, spreading redness), discontinue home remedies and seek professional medical attention. |

You can safely apply 2–3 times daily until symptoms ease, but avoid leaving it on for over 15 minutes.
