How to Tell If You Have Bed Bugs
If you think you have bed bugs, check the seams of your mattress and the joints of your bed frame for live bugs, shed skins and small dark spots. Below are the signs, where bed bugs hide, and when to call us about bed bug treatment in Sacramento.
What bed bugs and their signs look like
Adult bed bugs are flat, oval, wingless and rusty red, about 1/5 inch long. The younger nymphs are smaller and lighter in color. UC IPM adds that a foul or acrid smell can be present in heavily infested areas.
Bites are not a reliable sign, because several household pests bite and skin reactions vary, so the only way to confirm bed bugs is to find the bugs or their signs.
The signs are dark fecal spots, blood spots where a bug was crushed, egg cases and light-colored shed skins, and you will usually find them along the mattress seams and near the bed.
Where bed bugs hide
Most bed bugs hide within 6 feet of where people sleep or rest. About 85% are found in or near the bed, according to the research UC IPM cites. Start with the mattress and box spring seams, then check the bed frame and headboard joints and the cracks in nearby baseboards and furniture.
They are carried in on luggage, clothes, bedding and second-hand furniture. They can now be found even in the finest hotels and homes.
How to check for bed bugs
- Strip the bed and look along the mattress and box spring seams with a flashlight and a small mirror.
- Check the bed frame joints, the headboard, and where it meets the wall.
- Check everything within 6 feet of the bed, including baseboards and the cracks nearest it. Bed bugs can use cracks as narrow as a credit card.
- Look for the signs, not only live bugs: dark spots, shed skins, and blood spots on the sheets.
DIY versus professional bed bug treatment
UC IPM does not generally recommend over-the-counter bed bug products. It says their performance under actual field conditions is not known, and that total-release foggers are ineffective and can be harmful to residents.
Insecticide alone will not control an infestation, and confirmed ones should be managed by trained professionals. Eggs hatch in about 10 to 15 days at room temperature. So a professional bed bug treatment treats the places they hide and follows up to catch what hatches.
What to do if you think you have bed bugs
Wash all bedding and clothing in hot (120°F) water and dry it on the hottest setting. Vacuum along the mattress seams and baseboards. UC IPM advises both for small numbers of bed bugs.
If you remove an infested mattress or furniture, take it straight to the dump or mark it clearly as infested, and do not leave it on the curb. Then book an inspection so the treatment targets the right spots, and you can contact us or call the office below.
