That vintage dresser at the thrift store. The free couch your neighbor is giving away. The mattress listed on Facebook Marketplace. Used furniture is a fantastic way to save money — but it's also one of the most common ways bed bugs enter Arizona homes.

Here's what you need to know before you bring any secondhand furniture through your front door.

How Common Is This Problem?

Very common. Bed bugs are expert hitchhikers, and upholstered furniture is one of their favorite hiding places. A sofa, mattress, or bed frame from an infested home can harbor hundreds of bugs in its seams, joints, and crevices — all invisible to the untrained eye.

High-risk secondhand items include:

• Mattresses and box springs (highest risk)
• Upholstered sofas and chairs
• Bed frames and headboards
• Nightstands and dressers
• Used luggage and bags

The Golden Rule: Never Accept a Used Mattress

This one is non-negotiable. Mattresses are the primary habitat for bed bugs, and even a "clean-looking" used mattress can harbor a significant infestation. The risk simply isn't worth it.

If you need a new mattress and budget is a concern, look for sales at mattress stores, check for factory-second options, or consider a mattress-in-a-box brand. A new mattress is far cheaper than a professional bed bug treatment.

How to Inspect Used Furniture Before Buying

If you're considering secondhand upholstered furniture (other than mattresses), here's how to inspect it properly:

What You'll Need

• A flashlight
• A credit card or thin stiff card
• Disposable gloves (optional but recommended)
• A white sheet or tarp to place the furniture on

Step 1: Inspect in Good Lighting

Examine the furniture in bright light — ideally outdoors. Look for:

• Dark spots or streaks (fecal matter) along seams and in crevices
• Rust-colored stains (blood spots)
• Pale yellow shed skins in joints and folds
• Live bugs — small, flat, reddish-brown insects about the size of an apple seed

Step 2: Check All Seams and Joints

Use your credit card to probe along seams, under cushions, in zipper tracks, and in any joints or crevices. Bed bugs love tight spaces.

Key areas to check on a sofa:

• Under and between cushions
• Along the bottom seam where the fabric meets the frame
• In the folds of the armrests
• Along the back seam
• Underneath the sofa (flip it over)

Key areas to check on a bed frame:

• All joints and screw holes
• The slats and where they connect to the frame
• Any hollow sections of the frame

Step 3: Look for Eggs

Bed bug eggs are tiny (1mm), pearl-white, and sticky. They're often found in clusters in the deepest crevices. A magnifying glass can help.

Step 4: Smell Test

A heavy infestation produces a musty, sweet odor. If the furniture smells unusual, trust your nose.

What to Do If You're Unsure

If you've already brought used furniture home and you're not sure whether it's infested, here are your options:

For Hard Furniture (Dressers, Nightstands, Bed Frames)

• Inspect thoroughly using the steps above
• Treat with heat if possible — a clothes dryer on high heat for 30 minutes kills bed bugs in items that fit
• Apply diatomaceous earth to joints and crevices as a preventive measure

For Upholstered Furniture

• Steam clean the entire piece — steam at 160°F+ kills bed bugs on contact
• Vacuum thoroughly, paying special attention to seams
• Consider professional treatment if you have any doubt

For Mattresses

Seriously — don't bring used mattresses home. But if you already have, call a pest control professional immediately for an inspection.

Buying from Thrift Stores vs. Private Sellers

Thrift stores like Goodwill and Salvation Army typically inspect donated items and may reject infested furniture. However, this isn't foolproof — bed bugs can be missed during inspection.

Private sellers (Facebook Marketplace, Craigslist, curb finds) carry higher risk because there's no inspection process. Be especially cautious with free furniture left on the curb — it's often there because the owner discovered a problem.

Already Have Bed Bugs from Used Furniture?

If you've recently acquired secondhand furniture and are now seeing signs of bed bugs, don't panic — but do act quickly. The sooner you address the infestation, the easier it is to eliminate.
