Can my landlord charge me for bed bug treatment in Washington?

Only where the infestation was caused by the tenant. RCW 59.18.130(2) requires a tenant to assume all costs of extermination and fumigation for infestation caused by the tenant, and those last four words are the limit of it. A landlord relying on the subsection is asserting a fact about how the infestation started, and an invoice for one unit with no inspection of the units around it does not establish that fact. In Seattle the position is stated more directly still — the city's housing code says renters who report pests cannot be charged for extermination unless the renter caused the infestation.

Is an extermination charge the same as rent?

No, and the distinction carries real weight. RCW 59.18.283 requires a landlord to apply any payment a tenant makes toward rent before applying it to late payments, damages, legal costs or other fees, and provides that the tenant's right to possession may not be conditioned on payment of any monetary amount other than rent. A landlord may still pursue the charge through other lawful means, but it is not a rent arrear and it is not a route to possession.

What should my first response be?

A dated written dispute that asks for the evidence rather than argues about it. Request the inspection report for your unit, the inspection reports and dates for the units above, below and either side, the treatment history for the unit and building over the last two years, the specific basis for concluding you caused the infestation, and an itemised invoice. Give a date for the reply. Keep paying your rent in full while it is outstanding, and keep a copy of everything.

What if the charge is taken out of my deposit instead?

RCW 59.18.280 requires the landlord, within thirty days of termination and vacation, to provide a full and specific statement of the basis for retaining any of the deposit together with copies of estimates received or invoices paid to reasonably substantiate damage charges. A landlord who misses the thirty days is liable for the full amount of the deposit and is barred from asserting any claim or defence for retaining it, absent circumstances beyond their control. A court may award up to twice the deposit for an intentional refusal, and the prevailing party is entitled to costs and a reasonable attorney fee.

Can the charge be sent to collections or a tenant screening company?

Not if it is unsubstantiated. RCW 59.18.280(3)(b) provides that damages for wear resulting from ordinary use, or damages not substantiated by documentation equivalent to that required for a deposit statement, may not be charged to the tenant, reported to any consumer reporting agency, tenant screening service or prospective landlord, or submitted for collection by any third-party agency. If an undocumented bed bug charge appears on a screening report, that is the provision to raise.

What if my lease says I pay for all pest control?

RCW 59.18.230 makes any lease provision waiving a section or subsection of the Residential Landlord-Tenant Act unenforceable as against public policy, and prohibits a rental agreement requiring a tenant to waive or forgo rights or remedies under the chapter. A blanket clause moving the landlord's RCW 59.18.060(4) duty onto the tenant is aimed squarely at that. Where a landlord knowingly uses an agreement containing a prohibited provision, the tenant may recover actual damages, statutory damages up to twice the monthly rent, costs and reasonable attorneys' fees.

Can I take this to small claims court?

Small claims in a Washington district court has jurisdiction for the recovery of money only, up to ten thousand dollars in cases brought by a natural person. Deposit disputes are among the most common matters heard there, filing fees are modest, and lawyers do not ordinarily appear. It is a realistic route for a disputed extermination charge or a withheld deposit, and the documentation you built during the dispute is the case. Take advice before filing so you are clear about who to name and what to claim.

Q: Can I be evicted over this?

Not over the charge itself. Because an extermination charge is not rent, a landlord cannot condition your right to possession on paying it, and RCW 59.18.230(1)(b) prohibits threatening a tenant with eviction for failure to pay nonpossessory charges limited under RCW 59.18.283. What can create an eviction risk is withholding rent in response to the dispute, which is why the advice is always to dispute the charge in writing and keep paying rent in full and on time.

A bed bug charge on your ledger is an assertion by one party about a contested fact. It is not a judgment, it is not rent, and in Washington it is subject to a set of documentation rules most tenants never find out about — including one that governs where the charge can and cannot be sent if it is not substantiated.

This guide covers what the charge actually is, the four ways it usually arrives, the letter that answers it, and what happens if that letter does not work.

First, what the charge is not

Three things are true of an extermination charge in Washington and none of them is obvious from the ledger entry.

It is not rent. RCW 59.18.283(1) requires a landlord to apply any payment a tenant makes toward rent before applying it to late payments, damages, legal costs or other fees. So paying your normal rent does not accidentally pay down the bed bug charge and leave you short on rent. Subsection (2) goes further: except in the narrow circumstances of RCW 59.18.410, the tenant’s right to possession may not be conditioned on payment of any monetary amount other than rent.

It is not a threat of eviction. RCW 59.18.230(1)(b) states plainly that a landlord may not threaten a tenant with eviction for failure to pay nonpossessory charges limited under RCW 59.18.283.

It is not automatically collectable. RCW 59.18.280(3)(b) prohibits charging a tenant for damages not substantiated by proper documentation, and prohibits reporting those damages to a consumer reporting agency, a tenant screening service or a prospective landlord, or submitting them to a third-party collection agency.

None of that means the charge disappears. A landlord who believes a tenant caused an infestation retains lawful ways to pursue it. It means the charge has to be argued rather than simply imposed, and that the argument runs on evidence.

The four ways the charge arrives

Route 3 is the one most tenants meet, and the one with the hardest deadline attached. The thirty-day rule in RCW 59.18.280 does more work in practice than any argument about how the bugs got there.

Step one — do not withhold rent

This is the mistake that turns a winnable dispute into a losing one. Because the charge is not rent, refusing to pay rent does not put pressure on it; it creates a separate, much more serious problem with its own statutory procedure.

Pay the rent in full and on time. Dispute the charge separately, in writing. If you are considering withholding under RCW 59.18.100 or another remedy in the chapter, get advice on your specific facts first — those provisions have notice requirements, waiting periods and caps, and getting the sequence wrong is expensive.

Step two — the demand letter

The first letter should ask for evidence, not argue about biology. You are inviting the landlord to produce the file. What comes back — or does not — tells you what you are dealing with.

Subject: Written dispute of extermination charge — [unit address], charge dated [date], $[amount]

Date: [date sent]

To: [landlord or management company, at the notice address in the rental agreement]

Premises: [full unit address] · Tenant: [your name] · Charge disputed: $[amount], dated [date]

I am writing to dispute the extermination charge described above. I do not agree that I am liable for it, and I am asking for the documentation on which it is based.

RCW 59.18.130(2) makes a tenant liable for the costs of extermination only for “infestation caused by the tenant”. RCW 59.18.060(4) places the duty to control infestation during the tenancy on the landlord in all rental housing other than a single-family residence. So that I can understand the basis of the charge, please provide:

The inspection report for my unit, including the findings on the extent and apparent age of the infestation.

The inspection reports for the units above, below and adjoining mine, and the dates on which those inspections were carried out.

The bed bug treatment history for my unit and for the building over the last twenty-four months.

A statement of the specific evidence on which the conclusion that I caused the infestation is based.

An itemised invoice showing the work performed, the dates, and the addresses treated.

[Where relevant: I reported this infestation in writing on [date]. A copy of that notice is attached.]

[Where relevant: My unit is in a building with shared walls. Bed bugs travel between units through wall voids, outlet boxes and service chases, and I am not aware that any adjoining unit was inspected.]

Please respond in writing by [date, fourteen days from sending]. I am continuing to pay rent in full and on time, and I understand from RCW 59.18.283 that this charge is not rent and that my right to possession is not conditioned on it.

[Your name] · [phone] · [email]

Send it to the notice address in the rental agreement, keep the sent copy, and diarise the reply date.

Step three — read what comes back

A complete file. Inspection reports naming your unit and the units around it, dates, a technician’s assessment, and a clear evidential thread. If it exists, look at it honestly. There are genuine cases — the second-hand bedroom set on a dated delivery note, into a building with clean inspections all round — and this is what one looks like. Negotiating the amount is a better use of your time than fighting the liability.

A partial file. One invoice, no neighbouring-unit inspections, no assessment of how long the infestation had been established. That is the common outcome, and it is the position RCW 59.18.130(2) does not support. Reply once, briefly, saying which of the five items were not provided and that the charge remains disputed pending them.

Nothing at all. Note the non-response in writing. It matters later, and it is the point at which to call the Tenants Union of Washington State’s hotline or read the Washington Law Help material on pest infestations.

Step four — if it comes out of the deposit

The deposit route has the clearest rules in the whole dispute, and they are procedural rather than factual. Under RCW 59.18.280(1), within thirty days after termination of the rental agreement and vacation of the premises, the landlord must give a full and specific statement of the basis for retaining any of the deposit and include copies of estimates received or invoices paid to reasonably substantiate damage charges, together with any refund due.

If that does not happen inside thirty days, RCW 59.18.280(2) makes the landlord liable to the tenant for the full amount of the deposit, and bars the landlord from asserting any claim or raising any defence for retaining it, unless circumstances beyond the landlord’s control prevented compliance or the tenant abandoned the premises. A court may in its discretion award up to twice the deposit for an intentional refusal, and in any action brought by the tenant to recover the deposit the prevailing party is entitled to costs and a reasonable attorney fee.

So the first question about a deposit deduction is not “did I cause the bed bugs?” It is: what date did the tenancy terminate, what date did I vacate, what date is on the statement, and did an invoice come with it?

Give the landlord a written opportunity to refund before filing anything. A short letter setting out the dates, the amount, and the provisions above resolves a good share of these without a court.

Step five — small claims

RCW 12.40.010 gives the small claims department of each district court jurisdiction for the recovery of money only, up to ten thousand dollars in a case brought by a natural person. Deposit and charge disputes are among the most common matters heard there. Filing fees are low, procedure is simplified, and attorneys do not ordinarily appear.

What wins these is documentation, in date order: the original written notice, the photographs, the responses, the demand letter, the non-response, the deposit statement and its date. If you have followed the sequence in this guide and the notification guide, the file assembles itself.

Get advice before filing — on who the correct defendant is, what to claim, and whether your facts support the statutory damages provisions rather than just the amount of the charge.

General information, not legal advice. Whether a charge is enforceable, and what to do about it, depends on your lease, your building, your dates and your correspondence. For advice on your situation, contact the Tenants Union of Washington State, Washington Law Help, or a landlord-tenant attorney. Nothing here creates a legal relationship or substitutes for that advice.

A note to landlords

A charge that cannot be substantiated is worse than no charge at all: it is unenforceable under RCW 59.18.280(3)(b), it cannot be sent to collection or a screening service, and it converts a maintenance issue into a dispute with attorney-fee exposure attached.

If you intend to charge, build the file at the time. Inspect the surrounding units, keep the reports, record the assessed extent and age of the infestation, keep the invoices, and put the causation reasoning in writing while the technician is still standing in the room. If the file does not support it, absorb the cost — treating the building properly is cheaper than treating one unit repeatedly, and cheaper again than defending a charge that was never documented. The apartment operators’ page covers how the scope decision drives the whole cost.

We are not lawyers and nothing here is legal advice. If you need a written inspection report for a dispute, whichever side of it you are on, say so when you call, because a standard service ticket will not record extent or apparent age.
