Bed Bug Treatment

Bed Bug Extermination in the Rio Grande Valley

Finding bed bugs is stressful. They’re not a sign of a dirty home — they travel with luggage, on used furniture, in clothing, and through walls in multi-unit buildings. By the time most people realize they have them, the infestation has already spread beyond the mattress to the bed frame, furniture, baseboards, and nearby wall voids.

At Del Valle Pest Control, bed bug treatment is one of the more involved services we perform, and we treat it that way. We offer both liquid treatment programs and heat treatment, and we’ll tell you honestly which one makes more sense for your situation before any work begins.

How to Tell If You Have Bed Bugs

Bed bugs are small — about the size of an apple seed when fully grown — and they’re good at staying hidden. Here’s what to look for:

Bites on exposed skin while sleeping — often in a line or cluster on the arms, shoulders, neck, or legs. Not everyone reacts to bed bug bites, so the absence of bites doesn’t rule them out
Small blood spots on sheets or pillowcases — from bites or from rolling over a recently fed bug
Dark fecal spots on the mattress seams, box spring, headboard, or nearby furniture — these look like small ink dots and don’t smear when wet
Live bed bugs — check the seams of the mattress and box spring, the joints of the bed frame, and behind the headboard
Shed skins — bed bugs molt as they grow, leaving behind pale, translucent shell casings in areas where they hide
Tiny white eggs — found in cracks and crevices near harborage areas
A musty, sweet odor in the room — noticeable in more severe infestations

If you’re waking up with unexplained bites or have any of the signs above, don’t wait. Bed bug populations grow fast — a single female can be responsible for hundreds of new bugs within a few weeks.

Where Bed Bugs Hide

Most people associate bed bugs with the mattress, but by the time an infestation has grown, they’ve typically spread well beyond it. During an inspection we check:
In the bedroom:

Mattress seams and piping
Box spring interior and fabric
Bed frame joints and screw holes
Headboard — especially if it’s mounted to the wall
Nightstands and dressers
Baseboards and carpet edges along the walls

In living areas:

Sofas and recliners, particularly in seams and under cushions
Upholstered chairs
Curtains near the floor
Electrical outlets and switch plates on shared walls

In adjacent areas:

Closets and luggage
Wall voids, especially in apartments where bugs travel between units
Picture frames
Books and clutter stored near sleeping areas

The scope of the inspection determines the scope of the treatment. We don’t assume it’s limited to one room.

Treatment Options

Liquid (Chemical) Treatment
Liquid treatment is the most common professional approach and is appropriate for most infestations when followed correctly.
How it works:
We use a combination of residual insecticides, insect growth regulators (IGRs), and dust formulations applied to cracks, crevices, and harborage areas. The residual insecticide kills bugs on contact an continues working after the application. The IGR prevents eggs and nymphs from developing into reproductive adults, which is critical because eggs are largely resistant to liquid insecticides on their own.
Treatment areas include:

Bed frames and headboards
Mattress and box spring (treated, not soaked)
Baseboards and wall-floor junctions
Furniture joints and seams
Carpet edges
Nightstands and dressers
Electrical outlets on affected walls
Any cracks or voids near sleeping areas

How many visits does it take?
Liquid treatment requires multiple visits — typically two to four, scheduled ten to twenty-one days apart. This is not optional and it’s not a sign the first treatment didn’t work. Bed bug eggs are resistant to insecticides and hatch after the initial service. Follow-up visits eliminate the newly hatched nymphs before they reach reproductive age and break the cycle.
We’re going to be direct with you about this: any company that tells you they can eliminate a bed bug infestation with a single liquid treatment visit is not being honest with you. It takes multiple visits done properly. We’d rather tell you that upfront than have you disappointed.
Heat Treatment
Heat treatment is considered one of the most effective methods available because it kills all life stages — adults, nymphs, and eggs — in a single treatment.
How it works:
We bring industrial heaters, high-temperature circulation fans, and temperature sensors into the structure. The room or structure is raised to temperatures lethal to bed bugs — typically between 120°F and 140°F — and held there for several hours. Technicians monitor temperatures throughout the space and move items as needed to eliminate any cold spots where bugs could survive.
What makes heat treatment effective:

It penetrates into mattresses, furniture, wall voids, and other areas that liquid products can’t fully reach
It kills eggs, which liquid treatments don’t reliably eliminate in a single visit
It works in a single primary treatment session rather than requiring multiple visits spaced weeks apart
There is no residual chemical left behind after the treatment

What you need to do before heat treatment:
We’ll give you a specific preparation checklist, but in general, you’ll need to remove:

Aerosol cans (hairspray, spray paint, compressed air canisters) — these can rupture under heat
Certain medications that are heat-sensitive — ask your technician
Candles and wax-based items
Heat-sensitive electronics if your technician recommends it
Any items in fully sealed plastic bags, since these can trap cold air and create spots that don’t reach lethal temperature

You and your pets will need to be out of the treated area during the process, which typically takes most of a day.
Does heat treatment need a follow-up?
Heat eliminates what’s present at the time of treatment, but it leaves no residual protection. For that reason, many professionals, including us, recommend applying a residual insecticide after heat treatment as a supplemental layer of protection against any bugs that may be reintroduced. We’ll discuss this with you based on your situation.
Which Treatment Is Right for You?

	Liquid Treatment	Heat Treatment
Number of visits	2-4 visits	1 primary treatment
Kills eggs reliably	Requires follow-ups	Yes
Residual protection	Yes	No (without supplemental product)
Cost	Lower	Higher
Best for	Moderate infestations, budget-conscious approach	Severe infestations, hotels, apartments, fastest resolution

For severe infestations — particularly in hotels, apartments, and heavily affected homes — heat treatment followed by a targeted residual application gives the highest success rate.

What to Do Before Your Treatment Appointment

Preparation is not optional. Treatment effectiveness depends significantly on how well the space is prepared, and most warranties are voided if preparation instructions aren’t followed.
Before a liquid treatment:

Wash all bedding, clothing, and linens in hot water and dry on high heat — bag clean items in sealed plastic bags and keep them out of treated areas until cleared
Pull furniture away from walls so technicians can access baseboards
Remove and bag items from dresser drawers and nightstands
Reduce clutter on floors, especially in bedrooms
Vacuum carpets and floors thoroughly and dispose of the vacuum bag or canister contents outside immediately after
Do not use any store-bought bug sprays before the appointment — repellent products scatter bed bugs deeper into harborage areas and make treatment less effective

Before heat treatment:

Remove all aerosol cans, candles, wax items, and heat-sensitive medications
Do not bag items in sealed plastic — items should be spread out, not bundled tightly
Wash and dry bedding and clothing on high heat before the appointment and leave them accessible
Your technician will give you a complete checklist specific to your home

Bed Bug Treatments for Hotels, Apartments, and Commercial Properties

Bed bugs are a known risk in the hospitality and rental housing industries. The high turnover of guests and tenants, shared walls between units, and movements of luggage and belongings create regular exposure. We provide bed bug services for:

Hotels and motels
Apartment complexes
Dormitories
Nursing homes and assisted living facilities
Employee housing

For multi-unit buildings, we can inspect and treat individual units and common areas, and we provide documentation of service for management records. Proactive monitoring programs, including bed bug monitors placed in guest rooms or units, are also available for properties that want to catch problems early before they spread.

Serving the Rio Grande Valley and All of Texas

We provide bed bug treatment throughout the RGV including McAllen, Edinburg, Mission, Pharr, Harlingen, Brownsville, and surrounding communities, as well as across Texas including Laredo, Corpus Christi, San Antonio, Austin, Houston, and Dallas.
Our technicians are licensed by the Texas Department of Agriculture, and we carry general liability insurance and worker’s compensation coverage.

Warranties

Bed bug warranties vary based on the type of treatment and how thoroughly preparation instructions are followed. We offer:

30-day warranty
60-day warranty
90-day warranty

Warranty terms are tied to completing all recommended follow-up visits and following preparation instructions. We’ll go over the specific terms with you before treatment begins so there are no surprises.

What to Expect After Treatment

First few days: You may still see bed bugs. Bugs that were in deeper harborage areas will continue to emerge and contact the residual product. This is normal and expected — it doesn’t mean the treatment didn’t work.
Two to six weeks: Activity should decrease noticeably. Follow-up visits during this window eliminate newly hatched nymphs.
One to three months: With proper treatment and preparation, the infestation should be resolved. If you’re still seeing activity after completing all scheduled visits, contact us — we’ll assess the situation.

Frequently Asked Questions (FAQ)

How did I get bed bugs?

Bed bugs don’t come from dirt or neglect. They spread through travel, used furniture, clothing, luggage, and thorough walls in multi-unit buildings. Hotels, planes, movie theaters, and public transit are all common exposure points. Anyone can get them.

Can I get rid of bed bugs myself?

Store-bought sprays have very limited effectiveness against bed bugs and won’t reach eggs or bugs hiding deep in furniture and wall voids. Over-the-counter foggers are particularly ineffective — bed bugs move away from the fog and simply relocate. In most cases, DIY attempts delay professional treatment and give the infestation more time to spread.

Do I need to throw away my mattress?

Usually not. A mattress can typically be treated and enclosed in a bed bug mattress encasement rather than discarded. We’ll assess the condition of the mattress during the inspection and let you know. Throwing it out without treating the rest of the room doesn’t solve the problem — the bugs are in the bed frame, baseboards, and furniture too.

How long do I have to be out of my home for heat treatment?

Most heat treatments take the better part of a day. You, your family, and your pets will need to be out of the treated area for the duration and until the space has cooled to a safe temperature. We’ll give you a specific time estimate before your appointment.

Are the products used safe for my family and pets?

All products we use are EPA-registered and applied by licensed technicians trained in proper application methods. We’ll ask that you and your pets stay out of treated areas until they are dry, which typically takes a couple of hours. Once dry, treated surfaces are safe for normal contact.

I live in an apartment. Can my neighbor's unit re-infest mine?

Yes, this is one of the more frustrating aspects of bed bug control in multi-unit housing. Bed bugs can travel through wall voids, electrical conduits, and plumbing chases between units. If neighboring units are not treated at the same time, reinfestation is a real risk. We recommend notifying building management so adjacent units can be inspected.

Will my homeowner's or renter's insurance cover bed bug treatment?

Most standard homeowner’s and renter’s insurance policies exclude pest infestations, including bed bugs. We recommend checking your specific policy, but don’t count on coverage. We offer free inspections so you can understand the scope and cost before committing.
