Item #: SCP-(#)
Object Class: Euclid
Special Containment Procedures:
Homes suspected to inhabited by SCP-(#) are to be visited by foundation agents posing as contractors or city officials under the guise of an ordinary inspection of the home's smoke detectors; in the event that an instance of SCP-(#) is discovered it is to be terminated or recovered and replaced with a standard smoke detector. Following this the local authorities will be contacted and instructed to perform a fire safety assesment on the structure incase the presence of SCP-(#) indicates an underlying fire hazard.
Following incident SCP-(#) A in the event that a single home (usually abandoned), group of homes in close proximity, or non-home structure is found to contain a large number of instances of SCP-(#) the structure or structures and surrounding area are to be evacuated immediately under the pretense of a gas leak, or similiar story; following this a foundation inspection team will be dispatched to work alongside local authorities in order to determine what imminent hazard could lead to such a large grouping of SCP-(#).
Description:
SCP-{#) is an anomalous member of the arachnid family measuring aproximately 15 centimetres or 6 inches across, with most individual's weighing around 200 grams. SCP-{#) possess a disc shaped off-white shell bearing a strong resemblance to a typical household smoke detector with some individual's of the species bearing markings resembling serial numbers or brand logos, at the time of writing all such markings observed have been illegable having an apperance similiar to that of markings found on ordinary appliances after several years of wear.
SCP-(#) is typically found inhabitating homes in lower or middle income areas. Instances of SCP-(#) will enter homes at night through cat flaps or open windows before perching on an empty area of ceiling, typical perches are in hallways or stairwells where the homes inhabitants are unlikely to linger or look at the ceiling. Once situated on a perch SCP-(#) will retract its legs appearing almost indistinguishable from an ordinary smoke detector, during this time SCP-(#) will remain completely stationary leaving its perch only at night in search of food, typically consuming items such as house spiders, mice or leftovers.
Having situated itself SCP-(#) will remain in a home for an almost indefinite period or until the inhabited home catches fire; in the event of a fire SCP-(#) will rub its legs together periodically producing a high pitched noise strongly resembling a household fire alarm. It has been noted that SCP-(#) does not exhibit this behaviour in response to small fires that do not pose a genuine risk of destroying the inhabited home.
During a house fire SCP-(#) will reproduce via unknown means with new instances finding and inhabiting new homes seemingly at random. It has been observed that homes inhabited by SCP-(#) burn down at almost double the rate of homes not inhabited by SCP-(#) however it is unknown if SCP-(#) is directly responsible for these fires or if it is instead somehow capable of determining which homes are greater risk of fire, chosing to live in such homes in order to increase its chances of reproduction.
Incident Report SCP-(#) A:
During the search of an abandoned retail unit suspected of containing a taped copy of SCP-(redacted) foundation agents discovered the unit to be inhabited by aproximately (redacted) instances of SCP-(#), agents were instructed to contain all instances and no further action was taken. Aproximately (redacted) days later the retail unit and several surrounding structures were damaged by the detonation of a buried piece of unexploded ordinance left behind after WWII resulting in (redacted) civillian casualties.
