From the Guidelines
The treatment for bug bites typically involves addressing symptoms like itching, swelling, and discomfort, and for high-risk tick bites, prophylactic antibiotic therapy with doxycycline may be recommended within 72 hours of removal, as stated in the 2020 guidelines for the prevention, diagnosis, and treatment of Lyme disease 1. For most minor bug bites, the following treatments can be applied:
- Apply a cold compress to reduce swelling
- Use over-the-counter antihistamines like diphenhydramine (Benadryl) 25-50mg every 4-6 hours or non-sedating options like cetirizine (Zyrtec) 10mg daily to control itching
- Topical treatments such as 1% hydrocortisone cream applied 2-3 times daily for up to a week can reduce inflammation, while calamine lotion can soothe itchy skin
- For pain relief, acetaminophen (Tylenol) 500-1000mg every 6 hours or ibuprofen (Advil) 200-400mg every 6 hours can be effective Keep the bite area clean by washing with soap and water to prevent infection. Avoid scratching as this can lead to secondary infections. If you notice signs of infection (increasing redness, warmth, pus, or fever), severe allergic reactions (difficulty breathing, facial swelling, or hives), or if the bite is from a potentially dangerous insect like a black widow spider or scorpion, seek immediate medical attention. To prevent tick bites, measures such as using protective clothing, applying insect repellents like DEET, picaridin, or IR3535, and conducting frequent visual inspections of skin and clothes can be effective 1. It is essential to note that the risk of Lyme disease from a tick bite depends on various factors, including the species, stage, and degree of engorgement of the tick, as well as the geographic location of the bite 1. Therefore, prophylactic antibiotic therapy should only be considered for high-risk tick bites, and the decision to treat should be made on a case-by-case basis, taking into account the individual's risk factors and medical history.
From the FDA Drug Label

From the Research
Treatment for Bug Bites
- The treatment for bug bites can vary depending on the type of bite and the severity of the reaction.
- For tick bites, prophylactic antibiotic treatment with doxycycline can be effective in preventing Lyme disease if delivered promptly after the tick is removed 4.
- However, for simple insect bites, there is a lack of evidence for the efficacy of treatments such as antihistamines and topical corticosteroids, and recommendations are often based on expert opinion and clinical experience 5.
- In areas where Lyme disease is endemic, empirical treatment with antibiotics may be indicated if the probability of Borrelia burgdorferi infection after a tick bite is 0.036 or higher 6.
- Prevention of insect bites is also an important consideration, and methods such as topical repellents, impregnated clothing, and bed nets can be effective 7.
- For symptoms such as swelling, pain, and pruritus after insect bites, the use of concentrated heat has been shown to be an effective alternative to traditional treatments such as glucocorticoids and antihistamines 8.
Prevention and Management
- Preventing bug bites is an important step in reducing the risk of disease transmission and can be achieved through the use of repellents, protective clothing, and other methods 7.
- For simple insect bites, management may involve self-care measures such as applying cold compresses or topical creams to reduce itching and swelling.
- In cases where symptoms are more severe or persistent, medical attention may be necessary to rule out infection or other complications 5.
