If you feel bites in your apartment but exterminator after exterminator finds no bed bugs, the answer may be mites from a nest you can’t see. Here’s how to find the real source — from an Associate Certified Entomologist.
Why “mystery bites” with no bed bugs happen
When someone reacts to bites but no bed bug is ever produced, a trained entomologist works through a short list of causes: carpet beetle larval hairs, skin conditions, and — very commonly in the city — bird and rodent mites. Mites are parasites of their host’s nest. As long as the birds or rodents are present, the mites stay in the nest. The moment the host leaves, the mites leave too, dispersing along pipes, wires, and wall voids into the nearest living space.
Why high-floor and affluent homes see this
Pigeons and sparrows build nests in the exact places found on higher floors of nicer buildings: window air-conditioner units, decorative ledges and cornices, exhaust vents, and facade details. A penthouse or high-floor apartment is often closer to these nests than to street-level pests. The result is a distressing, invisible problem in an otherwise pristine home — and one that ordinary bed bug treatments never resolve, because the source is outside the room.
The real reason the bites keep coming back
- The source is the nest, not your bed. Treating furniture without removing the nest leaves the reservoir intact.
- They’re nearly invisible. Pinhead-sized specks are easy to miss, so the problem gets misdiagnosed as bed bugs or “in your head.”
- The entry point stays open. If the AC unit gap or vent isn’t sealed, a new nest re-starts the cycle.

How we resolve bird and rodent mites
- ACE inspection to confirm mites versus bed bugs versus another cause — and to locate the nest at the source (AC units, ledges, vents, wall voids).
- Nest removal and treatment of the source and the areas the mites dispersed into.
- Exclusion — sealing the entry point so a new nest can’t restart the problem.
See our mite control service for the full approach — it’s an underserved niche most companies don’t diagnose correctly.
What to expect
We confirm the cause, find and remove the nest, seal the entry point, and treat the affected areas — then explain in plain language what was happening. We serve Manhattan and Brooklyn in English, Spanish, and Chinese.

For rodents, NYE provides rodent exclusion that seals the entry points, not just trapping. ACE-led work comes with a client portal of service reports and photos, fully bilingual service, and no long-term contract.
Bird & rodent mite FAQ
Why am I getting bitten but no bed bugs are found?
A frequent cause in NYC high-rises is bird or rodent mites. After a pigeon or sparrow nest or a rodent nest is abandoned, the mites leave the nest to look for a host and can bite people, even though no bed bug or visible insect is ever found. An entomologist inspection can confirm the source.
What are bird mites and where do they come from?
Bird mites are tiny parasites that live in bird nests. In the city they most often come from pigeon or sparrow nests built in window AC units, on ledges, in vents, or under facade details. When the birds leave or the young fledge, the mites disperse indoors seeking a host.
Can you see bird or rodent mites?
Barely. They are pinhead-sized and often appear as tiny moving specks, easy to miss. Because they are so small and tied to a hidden nest, mite problems are frequently misdiagnosed, which is why an entomologist inspection matters.
Why do the bites keep coming back after treatment?
Because the true source is the nest, not your furniture. Until the bird or rodent nest is located and removed and the entry point sealed, mites keep dispersing indoors and the bites return. Treating the room without removing the source rarely resolves it.
How do you get rid of bird or rodent mites?
By finding and removing the nest at the source, sealing the entry point so it cannot recur, and treating the affected areas the mites dispersed into. Source removal is the step that ends the cycle.
