Insect Bites

While most insect bites are harmless and only cause minor irritation, some can cause more serious reactions, especially for people who are allergic to insect venom. We offer a range of treatments for insect bites, including over-the-counter medications, topical creams, and antihistamines, which can help alleviate symptoms such as itching, swelling, and redness.

Common treatments

• Antihistamines: reduce the histamine response responsible for itching and swelling. Available in tablet or liquid form, taken orally or applied topically.
• Topical creams and ointments: applied directly to the skin to reduce itching and swelling; some contain anesthetic agents for immediate relief.
• Corticosteroids: reduce inflammation and swelling, available as topical creams/ointments or in oral form.
• Pain relievers: over-the-counter options such as ibuprofen or acetaminophen alleviate pain.

If an individual experiences a severe allergic reaction to an insect bite — such as difficulty breathing or swelling of the face or throat — they should seek immediate medical attention.

Insect bites in Canada

Canada is home to a wide variety of insects, many of which can bite or sting humans. Common examples include:

• Mosquito bites: prevalent during warmer months; can cause itching and redness.
• Black fly bites: small, aggressive insects that bite exposed skin, causing itching and swelling.
• Tick bites: common in wooded areas; ticks can carry diseases such as Lyme disease and cause redness, itching, and a bulls-eye rash.
• Wasp and bee stings: cause pain, swelling, and redness.
• Ant bites: several species, including carpenter ants and fire ants, cause itching and redness.
• Spider bites: including from the black widow and brown recluse; can cause pain, swelling, and in some cases more severe symptoms such as fever and muscle cramps.

Some individuals may be allergic to insect bites or stings, which can cause more severe reactions. If you experience difficulty breathing, swelling of the face or throat, or severe pain, seek medical attention immediately.

Preventing insect bites

• Wear protective clothing: long-sleeved shirts and pants, especially during peak mosquito and black fly seasons. Light-coloured clothing can also help deter insects.
• Use insect repellent containing DEET, picaridin, or IR3535 on exposed skin and clothing, following label instructions.
• Avoid peak insect activity: mosquitoes and black flies are most active at dawn and dusk; bees and wasps are more active during the day.
• Remove standing water around your home, such as bird baths, buckets, and flower pots, where mosquitoes breed.
• Use window screens to prevent insects from entering your home.
• Be careful with food when eating outdoors — keep it covered.
• Keep your yard tidy: trim grass and bushes regularly and remove debris.
• Wear shoes outdoors, especially in areas where ants and other biting insects are prevalent.

By following these tips, you can reduce your risk of getting insect bites and enjoy your time outdoors with peace of mind. If you do get an insect bite, consult a pharmacist for advice on the best treatment for your symptoms.
