Examples of bedbug bites.

The cautionary bedtime rhyme may be more easily said than done: Sleep tight. Don’t let the bedbugs bite.

Toronto Public Health has had an increase in calls about bedbugs in the past few years, suggesting the small, nocturnal blood-suckers have increased in numbers. And recent media attention has put bedbugs in the headlines.

“I have seen an increase in the number of patients with bedbug bites,” says Dr. Sophie Hofstader, a dermatologist who has been with The Scarborough Hospital for over 50 years. “I see at least one or two cases a week.”

Not everyone reacts to bedbug bites, says Dr. Hofstader, and reactions can look different from person to person.

What should you do if you are battling a reaction to bedbug bites? Dr. Hofstader shares some tips:

1. Get rid of the bedbugs. If you are unsure if they are in your home, use a flashlight at night and shine on your mattress. Bedbugs are difficult to find in daylight. If they are present, you will likely see them trying to escape the sudden light.
2. Try to avoid scratching the bites.
3. Apply ice to the bites.
4. Take antihistamines to reduce the desire to scratch.
5. Apply an over-the-counter anti-itch lotion.
6. If you have bites, stay covered up when sleeping to avoid getting more. Clothing with elastic around the waist, ankles and wrists will help keep them off your skin.
