What Do Bed Bugs Look Like?

Bed bugs are nocturnal parasitic pests found around worldwide including Denver, Boulder, and throughout Colorado. Adult bed bugs are reddish brown, wingless, and are about the size of an apple seed. 

Lighter colored bed bug nymphs are smaller than  adults and are nearly invisible unless they’ve had a meal.

Bed bug eggs are about the size of a pinhead and pearl-white. Without magnification, they are quite hard to see.

Frequently Asked Questions

Bed Bugs FAQs

Bed bug bites are relatively harmless, meaning they do not transmit any known diseases to humans. Bites are typically small red bumps or welts. They can become infected and may require medical attention, but that is not too common. While not a physical threat to people, infestations of this nature can be extremely stressful for homeowners. Bed bug problems can also be quite damaging to companies, especially in an age where good news travels fast and bad news even faster.
Wherever you find people (especially high levels of human traffic) you could find these pests. Hitchhikers by nature, bed bugs make their way from place to place on people, bags, and other personal belongings, as well as possessions. Used mattresses and secondhand furniture and clothing seem to be especially popular for these bugs. You can encounter them in hotels and airports, on airplanes and other public transportation, in retail stores and movie theaters. Residential environments are also seeing an increase in activity; this includes single-family dwellings, apartment buildings, and other types of multi-housing complexes.
Evidence of a bed bug problem include, but are not necessarily limited to:
  • Reddish stains or dark bed bug excrement on bed sheets, mattresses, and box springs.
  • Bed bug bites on limbs and/or other exposed skin
  • Live bed bugs (all stages)
If you’ve found these biting pests in your home or business, do not throw away your mattress and think the problem has been resolved. Though they are called bed bugs, they will hide out in other areas. For comprehensive bed bug extermination, seek out the help of a pest control company like EnviroPest that specializes in the control of this pest.
At EnviroPest, we take care of bed bug infestations using a couple of treatment methods. Based on your situation, we’ll eliminate bed bugs with a heat treatment or through the use of conventional techniques. Either option is deadly to bed bugs, but not a concern for people and pets.
We take bed bug issues very seriously and are committed to helping as soon as possible. In most cases, we can respond the same or very next day.
The cost for treating bed bug depends upon the severity of the infestation, the number of rooms infested, and other factors. For more information on bed bug pricing, please give us a shout fill out the form below to request an estimate.
Be vigilant when it comes to bed bugs. You should:
  • Inspect hotels or other commercial lodgings when away from home. If you suspect activity, request a new room or seek accommodations elsewhere.
  • Hold purses and bags in your lap rather than place on the floor or seats of public transportation.
  • Be very careful when it comes to bringing used mattresses, furniture or clothing into your home.
  • Wash newly purchased clothing in the hottest water permitted by the fabric as soon as you bring items home.
  • Unpack outside your home or in the garage when returning home from a trip. This will keep any hitchhiking bed bugs out of your home.

Great experience with the pest control service. Alexander did a thorough job spraying both the inside and outside of the home and took the time to explain what they were doing. I especially appreciated that he didn’t just treat the home but also pointed out areas around the house that could allow pests to get inside and recommended repairs and preventative measures to help keep them out. The service was professional, thorough, and informative, and I appreciated the attention to detail. I would definitely recommend them to anyone looking for reliable pest control and helpful advice from Alexander on preventing future pest problems.

Our garage had been infested with mice. They left quite a mess. EnviroPest has systematically worked to eradicated the mice, mitigate entry points, and most recently completed a thorough cleanup and sanitation process. Along the way, they have all been professional, friendly, and have gone out of their way to explain their findings and recommendations. I never felt like we were being upsold. Overall very satisfied and would call them again if needed.

Mark has come to service my property a few times and does a great job answering questions and focus on my areas of concern. I like having the rapport with someone familiar with my previous service and property needs.
