What Are Bed Bug Bites?
Bed bugs are small, nocturnal insects that hide in places like mattress seams, bed frames, and furniture crevices. They come out at night and feed on human blood. Causes of bed bugs entering the home include bringing in used furniture, lack of cleanliness, or bed bugs arriving with luggage during travel.
Bed Bug Bites Symptoms:
- Red welts in clusters or lines
- Itching that becomes worse over time
- Inflammation and minor swelling
- No immediate pain during the bite
Tip: Check your mattress seams and behind headboards for signs of an infestation.
What Are Mosquito Bites?
Mosquitoes are flying insects attracted to body heat and carbon dioxide. Mosquito bites can cause pain, irritation, and more discomfort in children. They bite to draw blood, usually leaving behind itchy welts.
Symptoms of Mosquito Bites:
- Round, raised, reddish bumps
- Intense itching right after the bite
- Occasional blistering or mild swelling
- Visible mosquitoes nearby
Tip: Mosquitoes are more common in areas with stagnant water and high humidity.
