Bedbugs are tiny blood-feeding insects that feed on human blood. They live in cracks and crevices around the home, especially near beds and couches. The bites from these little creatures are very painful and can last for weeks.

While it’s true that the bites of mosquitoes and bedbugs look similar, they are not. Mosquitoes usually bite at dawn or dusk, whereas bedbugs tend to bite at night. Bedbug bites are often red and raised welts, whereas mosquito bites are flat and smooth. If you suspect you might have a bedbug infestation, contact pest control professionals immediately.

Mosquito Bites vs Bed Bug Bites

Mosquitoes have been around since ancient times and were originally native to North America. In fact, they were first discovered in Egypt over 4000 years ago. Over time, mosquitoes have become a nuisance in many parts of the world, especially in tropical climates where they breed year-round. While mosquitoes can carry a wide variety of illnesses, some of them are much worse than others.

Bed bugs are small, reddish-brown insects that live in warm environments and feed off blood. They are often found in places where people sleep, including bedrooms, couches, and even cars. Bedbugs are not just parasites. They actually serve a purpose to their environment. These little critters help maintain balance in ecosystems by eating other insects. However, if left untreated, bedbug bites can cause itching, swelling, and skin discolorations.

While mosquitoes may look similar to bedbugs, they do not share the same lifestyle. Mosquitoes are active at night while bedbugs prefer daytime activity. Mosquitoes only need a single meal per day while bedbugs require several meals throughout the week. After feeding, mosquitoes rest in dark spots until the sun comes out again. Once the sunlight hits their bodies, they begin to move around looking for food. On the other hand, bedbugs hide away in dark spaces until the morning when they emerge to search for a place to rest. If you notice any of these behaviors, it could mean that you have a problem with bedbugs.

How to determine whether you are bitten by Mosquito or Bed Bug

To determine whether you have a bedbug infestation, check for telltale signs. Bedbugs leave behind tiny droppings called fecal matter. Look for these droppings near cracks or crevices in furniture, wall voids, or under beds. You might also find dried-up blood spots on your sheets. These spots are likely caused by bedbugs chewing on you while you slept. Another way to identify bedbugs is by noticing the small black marks they leave on your skin after feeding.

Bed Bug Bites

Mosquitoes bite primarily to obtain a meal of blood. Their saliva contains an enzyme that helps them suck blood from humans. Mosquitoes’ primary hosts are birds, bats, reptiles, amphibians, mammals, and humans.
