A mammoth wasp nest has been found in an abandoned house in Spain.
The seven-metre (22ft) nest was discovered by police who were contacted by worried neighbours in San Sebastien de la Gomera, Think Spain reported.
Experts say the nest must have been made by an invasive species of wasp which had migrated from Africa as the native variety would not build one so large.
The Canary Islands are just 100km from Morocco by water.
The home has been cordoned off as police try to locate the owners of the property...and presumably decide what to do with all those wasps.
According to National Geographic, wasps are distinguishable from bees by their pointed lower abdomens and the narrow "waist".

It adds: "Despite the fears they sometimes evoke, wasps are extremely beneficial to humans.
"Wasps are so adept at controlling pest populations that the agriculture industry now regularly deploys them to protect crops."
The venom from a wasp sting typically causes a swollen, itchy, red mark to form on the skin which can be painful but harmless in most cases. A small percentage of the population is allergic to wasp or bee stings, which can lead to anaphylaxis.
<em>Triatoma infestans </em> Look out for it in: Mexico, Central and South America Why you should fear it: Assassin bugs transmit Chagas disease, a long-term, chronic disease that can ultimately cause serious cardiac and digestive problems. Notorious victim: Charles Darwin met one on his first trip to Argentina.
<em>Lonomia obliqua </em> Look out for it in: Brazil, Argentina, and neighboring countries Why you should fear it: The caterpillars release a powerful toxin that can cause internal bleeding and massive organ failure. Notorious victim: A young Canadian tourist walked barefoot through a resort and stepped on five. Although local hospitals carried an antivenin, she didn't seek treatment until she returned home--a mistake that cost her her life.
<em>Culicoides spp. </em> Look out for it in: Everywhere. Why you should fear it: Also called no-see-ums, biting midges are a serious annoyance in the Scottish Highlands--so much so that tourists check the Biting Midge Forecast before heading out for a round of golf or a trek to a distillery. In Brazil and around the Amazon, they transmit Oropouche fever. Notorious victim: According to a community study, the biting midge broke up marriages in Hervey Bay, Australia, presumably because couples were forced to spend more time indoors together.
<em>Paederus sp. </em> Look out for it in: Most of the world. Why you should fear it: The beetle lands on the skin but doesn't bite. People tend to want to slap it, which releases a nasty poison called pederin that causes horrible blisters and welts. Notorious victim: Our troops stationed in Iraq. The beetles tend to swarm around the bright lights at military bases.

<em>Vespa mandarina japonica</em> Look out for it in: Japan, China, Taiwan, Korea Why you should fear it: Stings deliver a powerful neurotoxin that could be fatal. Notorious victim: Dr. Masato Ono, the world's leading expert on the giant hornet, said the sting felt like "a hot nail through my leg."
<em>Taenia solium </em> Look out for it in: South America, Africa, Asia, and parts of Europe and North America Why you should fear it: While modern livestock management here at home has practically eliminated tapeworm-infested pork, the tapeworm eggs can be spread directly from one infected person to another. How? Let's just say that it's really, really important to wash hands after going to the bathroom-- and leave it at that. Notorious victim: A woman in Arizona went into surgery thinking she had a brain tumor, and woke up later to learn that the cause of her problems had been a tapeworm, not a tumor.
<em>Ixodes scapularis </em> Look out for it in: Eastern United States (other species that transmit Lyme are found in the West and in Europe) Why you should fear it: The nymphs transmit the miserable and difficult-to-treat Lyme disease Notorious victim: Polly Murray, a resident of Lyme, Connecticut, battled the disease for decades and led the fight to get it properly identified, diagnosed, and treated.
<em>Tunga penetrans </em> Look out for it in: Tropical beaches in Latin America, the Caribbean, India, and Africa. Why you should fear it: Tiny fleas burrow under toenails and lay eggs, creating awful sores and possible infection Notorious victim: Members of Christopher Columbus' crew were made so miserable by chigoe fleas that they cut off their own toes to get rid of the bugs.
<em>Centruroides sp. </em> Look out for it in: Southern United States, Central and South America Why you should fear it: The venom can cause severe pain, difficulty breathing, and can be fatal to small children. Notorious victim: A little boy vacationing with his family in Mexico stepped on a scorpion in his shoe. He was flown to a hospital in San Diego, placed on life support, and did survive.
<em>Cimex lectularius</em> Look out for it in: Your bed Why you should fear it: After hearing about all these other nasty creatures, you aren't still worried about bed bugs, are you? Bed bugs may be annoying, but they are not known to transmit disease. They may cause a dreadful allergic reaction, but you'll survive. Bed bugs have always been around; overuse of toxic pesticides drove them away for a few decades, but fortunately, we now realize that the chemicals were far more dangerous than the bugs. Notorious victim: You.
