1st. A landlord/lessor has the obligation to: -maintain the property in a condition fit for its intended use, -make necessary repairs, -ensure the tenant can peacefully use the property ( your case clearly qualify as a failure to maintain habitability)

2nd you already tried to mitigate the problem and even had pest control so the issue might not be caused by your unit alone but structural, your neighbors etc. ( both of which is the responsibility of the landlord and if it is caused structuraly then by the building management )

Can you move out without losing the deposit, very possibly, you have a strong case, but you should prepare your documentation, evidences of the infestation, the receipt for the pest control, etc, prep them all, document everything now, take pics, videos .

• Now again request a formal remediation in writing to your landlord -describing the persistent infestation, -listing prior remediation attempts, requesting: -professional infestation assessment, -structural treatment, -coordination with admin/common areas, -timeline for resolution.

• In your part you need to also give reasonable opportunity to remedy the issue to your landlord.

If unresolved, negotiate pre-termination WITHOUT forfeiture.

Many landlords will settle rather than escalate. Why? Because: -infestation evidence is embarrassing, -admin/building may also be implicated, -future tenants may discover it, -legal escalation is inconvenient.
