Who Pays for the Bed Bugs

Bed bug liability in rental housing

Bed bug laws in Delaware
Who pays for treatment?

Bed bug statute

Delaware is unusual in requiring a visual inspection before every letting, and in spelling out what counts as evidence — live bugs, shed carapaces, eggs, or blood spotting on linens. Clocks are tight: acknowledge within 120 hours, inspect within 120 hours, treat within 14 days. But there's a trap that decides who pays. Report within 60 days of moving in, or within 30 days of an infestation being found next door, and the landlord covers everything. Miss both windows and you share the cost of treating your own unit — unless you're in public housing, which is carved out.

What the law actually says

Del. Code tit. 25 § 5317 (landlord and tenant obligations relating to bed bug infestation). (a) Before renting, the owner or property manager shall visually inspect the unit for evidence of bed bugs — a living bed bug, a carapace, eggs or egg casings, or brownish or blood spotting on linens, mattresses or furniture — and shall not show, rent or lease a vacant unit the landlord knows or reasonably suspects is infested. (b) No duty to inspect absent notice, but an infestation evident on visual inspection counts as notice. (c) Before renting, disclose to a prospective tenant whether adjacent units are infested or under treatment. (d) On notification by anyone finding or reasonably suspecting infestation in a unit or common area: acknowledge the complaint within 120 hours; inspect or obtain investigatory services from a pest management professional within 120 hours; on a determination of infestation, obtain and provide remedial services within 14 days of notification. (f)(1)-(2) Cost allocation: the landlord bears investigation and remediation costs where the tenant reports within 60 days after occupancy, or within 30 days of a bed bug infestation being discovered in an adjoining unit; otherwise the tenant shares reasonable remediation costs for their own unit — but a tenant shall not be required to share costs in properties managed by a state or local government housing authority. Definitions (ch. 51): 'bed bug remediation' means action by the landlord that substantially reduces the presence of bed bugs in a dwelling unit for at least 60 days; 'pest management professional' means a person licensed by the State to apply pesticides to the property of another.

What to do, in order

  1. Photograph everything before you touch it

    Live insects, shed skins, dark staining along the mattress seam. Timestamps are the evidence.

  2. Notify the landlord in writing

    Email or certified letter, never a phone call alone. Written notice is what starts the clock in every state that has one.

  3. Do not throw out furniture yet

    Discarded items can't be inspected, and moving them spreads the infestation down the hallway.

  4. Let the deadline above run

    Escalating before it expires generally forfeits the remedy.

  5. Escalate to the housing agency, then to court

    An independent inspection report is worth more than your own photographs. Rent withholding rules vary sharply — check the section above before you try it.
