When you go to bed at night, you may not be alone. Your bed, bedroom, and even your body could be housing insect invaders that will feast on you in your sleep. Bedbugs, in particular, have been on the rise over the past decade, building up a tolerance against chemical pesticides and becoming a real threat to humans. But they are not the only creatures lurking in your bedroom. From mosquitoes to fleas, there are many critters that see your bedroom as a buffet.

When the Bedbugs Bite

Bedbugs are small, brownish-red insects that are about a quarter of an inch in size. They release an anesthetic when they bite, which makes it difficult to feel them feeding on your blood. If you wake up with small, inflamed, itchy bumps, it may be an indication that you have bedbugs. They can crawl onto clothing or hide in the seams of bags and luggage, and they have been found in many places beyond just bedrooms. Bedbugs are also very patient and can survive without a meal for over a year. Getting rid of them requires professional help, as they can hide in hard-to-reach places like behind wallpaper and under carpeting.

If you suspect that your home has been invaded by bedbugs, you need to carefully inspect areas where they are likely to hide. Look for brown spots on your mattress and couch seams, and check your sheets and pillowcases. However, bedbugs are experts at hiding during the day, so you may need to search for discarded exoskeletons or tiny blood-filled fecal spots to confirm their presence. You might also detect a musty, sweet odor. Another way to identify bedbugs is to use sticky strips around your bed to catch any that travel from their hiding place to feed. Although bedbug bites can be very itchy, they are not usually associated with disease transmission.

Mosquitoes, on the other hand, are capable of transmitting serious diseases such as malaria, encephalitis, West Nile, and yellow fever. Female mosquitoes are the ones that bite, and they are attracted to people through visual cues, carbon dioxide, lactic acid, heat, and sweat. Mosquitoes breed in stagnant water, so eliminating standing water is an effective way to control their population. If you do get bitten by a mosquito, you can usually relieve the itchiness with over-the-counter remedies. If you find that your home is infested with bedbugs, the best strategy is to use an integrated pest management approach to eliminate them.

Fighting Off Fleas and Dust Mites

  • Keep the areas around your bedding clean and free from clutter.
  • Wash all bedding in hot water to kill any fleas or dust mites present.
  • Use non-chemical options like diatomaceous earth as a treatment.
  • Use chemical pesticides specifically designed for indoor use.
  • Apply heat to affected areas to kill fleas and dust mites.
  • Regularly check treated areas with monitoring devices, such as sticky strips.


Fleas are tiny parasites that typically feed on furry pets, but if they are hungry enough, they will bite humans as well. Fleas can survive for months in bedding and carpeting, and only 5% of the fleas in your home are adults. The other 95% are in the form of eggs, larvae, and pupae. Fleas can also carry diseases like Bubonic plague and typhus, but they are easier to get rid of than bedbugs. You can use flea growth and development inhibitors or pesticides to eliminate them. Flea repellents with DEET are also available to make you less appealing to fleas.

Dust Mites

Dust mites do not bite, but they can cause allergies and asthma problems due to their feces. They feed on dead skin cells shed by humans and are less than 1/100 of an inch long. You can control dust mites by using high-efficiency air filters, reducing humidity, washing bedding weekly, and vacuuming regularly. Daily dusting can also help keep them under control.
