Bed bugs hitch on luggage, clothing, bedding, and furniture. CDC states that how clean a place is does not determine whether bed bugs are present. UC IPM says confirmed infestations should be managed by trained professionals. In San Marcos that still starts with an inspection of the unit, not a method chosen on the phone.
Confirm the infestation before you compare methods
EPA and UC IPM: bites on the skin are a poor way to diagnose an infestation. People react differently. Some do not react at all. Distinguishing bed bug welts from other bites is difficult to impossible. Confirm the pest with physical evidence: live bugs, dark fecal spots, blood spots, eggshells, and shed skins. UC: current research indicates 85% of bed bugs are found in or near the bed, so start at the mattress, box spring, bed frame, and headboard.

Heat versus chemical is a written proposal, not a blog choice
UC IPM lists nonchemical tactics such as vacuuming, washing bedding at high temperature, steam or heat treatment, and sealing hiding places. Insecticides may be required for serious infestations, and insecticides alone will not control bed bugs. In California, providers of heat services must be licensed and bonded by the Structural Pest Control Board.
This page does not publish a room temperature, a dwell time, or a promise that you sleep in the bed the same night. Those details belong on the company’s written scope after it has seen the unit. Ask each bidder:
- Which rooms were inspected, and what evidence was found.
- Whether the proposal is heat, chemical, or both, and which products or equipment will be used.
- How many visits are included, and what monitoring happens after.
- What prep you must do, and what happens if prep is incomplete.
- Whether adjacent units will be inspected in a multi-family building.
What bed bug treatment costs: named national figures

Renting in San Marcos: AB 551 reporting
This is not legal advice. California Civil Code section 1954.602(a), added by AB 551, states a landlord shall not show, rent, or lease to a prospective tenant any vacant dwelling unit the landlord knows has a current bed bug infestation. Landlords must give tenants written bed bug information covering identification, behavior, prompt reporting, and cooperation with pest control.
Under Civil Code section 1954.605, after a pest control operator inspects units, the landlord must notify the tenants of those inspected units in writing within two business days of receiving the operator’s findings. Civil Code section 1942.5 addresses specified retaliatory actions after a tenant gives notice of a suspected infestation. Report in writing and keep a copy.

Prep the matched company actually assigns
UC IPM: wash bedding and clothing in hot (120°F) water and dry on the hottest setting. Vacuum seams and harborage. Do not move items from an infested room into a clean one. Consumer aerosol foggers are not effective and can be harmful. Your technician’s prep list is the list that counts for that job. This page does not promise that one visit ends the infestation if prep is perfect.
Frequently asked questions
How fast does bed bug heat treatment work in San Marcos?
Only the written proposal can say. UC describes commercial heating as one licensed method. It does not authorize an overnight-return claim on this page.
Can I treat bed bugs myself?
UC: confirmed infestations should be managed by trained professionals. EPA: find an infestation early, and do not misidentify it. Store foggers are not the plan.
Why would a San Marcos unit get bed bugs?
UC and CDC: people bring them on luggage, clothes, bedding, furniture, and other objects, including second-hand mattresses. This page does not publish local call-volume or campus-turnover observations.
Is my landlord responsible for bed bug treatment?
AB 551 and the Civil Code sections above set landlord notice, information, and vacant-unit rules. Report in writing. For your lease, get legal advice if you need it.
How much should I expect to pay?
HomeGuide puts heat at $1 to $3 per square foot, with the full job typically $2,000 to $6,000 for a 2,000 sq ft home (HomeGuide national benchmark)
