Bed Bug Expert Witness
Science-based opinions on infestation, timeline, and response for tenant habitability, hotel guest, and multifamily bed bug litigation.
Bed bug cases turn on biology and timelines
Who knew about the infestation, when it started, and whether the response was reasonable are usually the central questions in a bed bug lawsuit. Each one has an entomological answer. Adam Holt, BCE, reviews the physical evidence and the paper trail to explain how the infestation developed and whether the people responsible for the property acted the way a reasonable owner or pest control provider should have.
Case types
- Residential habitability: tenant claims against landlords and property managers, including rent abatement and constructive eviction theories
- Multifamily and affordable housing: spread between adjoining units, building-wide programs, and inspection practices
- Hotels and short-term rentals: guest exposure claims, room history, housekeeping detection practices, and response protocols
- Senior living and healthcare: resident exposure, facility protocols, and vendor oversight
- Pest control service disputes: treatment failure, missed follow-ups, and contract performance
- Furniture, moving, and storage: introduction of bed bugs through rented, sold, or transported goods
Questions Adam answers
- Was there an infestation, and how extensive was it?
- How long was it likely present, and could it predate the tenancy or the guest's stay?
- Were the signs visible to housekeeping, maintenance staff, or prior inspectors?
- Was the treatment plan consistent with recognized industry practice, including follow-up inspections?
- Did occupant preparation or cooperation affect treatment outcomes?
- Did the infestation spread from an adjoining unit or common area?
Work product
Adam reviews pest control service records, invoices, work orders, tenant or guest complaints, maintenance logs, photographs, and video. Where it helps the case, he conducts site inspections and identifies specimens. He then prepares written reports, declarations, and rebuttal opinions, helps counsel prepare for opposing expert depositions, and testifies at deposition and trial.

Frequently Asked Questions
Can you determine how long a bed bug infestation has been present?
Often, within a reasoned range. Population size, the life stages present, the accumulation of cast skins, eggs, and fecal spotting, and the distribution of activity through a unit all inform an estimate. Adam explains the basis and the limits of that estimate so it holds up under cross examination.
Can you identify specimens from photographs?
Frequently, if the images are clear enough to show diagnostic features. Physical specimens are preferred, and Adam can advise counsel on how to collect and preserve them.
Do you give opinions on bite injuries?
Adam addresses whether exposure to bed bugs was plausible and consistent with the evidence. Medical diagnosis and causation of injuries are left to qualified physicians, and he can coordinate with your medical expert.
Do you evaluate whether a landlord or hotel responded reasonably?
Yes. Response time, inspection practices, treatment methods, follow-up, and communication with occupants are compared against recognized industry practice and the facts of the property.
