Mass infestation of the Moscow region by spiders of the species karakurt, also known as 'black widow,' should not be expected.

Consensus

Massive infestation of kaракurt spiders in the Moscow region is not expected.
Kaракурт spiders have been observed in Moscow and the Moscow Region for several years.
These spiders primarily arrive from southern regions such as Krasnodar Krai, Crimea, Rostov Oblast, and Orenburg Oblast.
Spiders can be transported via shipments of vegetables and fruits.
Young kaракурт spiders can travel up to 500 kilometers using wind and silk threads.
The survival and reproduction of kaракурt in the Moscow climate is uncertain and may only be seasonal.
Kaракурт is considered a dangerous spider due to its venom, but it bites only when provoked.

Expert Olga Voronova from the Russian Gardeners' Union stated that summer in the Moscow region will see invasions of caterpillars, millipedes, and slugs due to mild winter, early warming, and abundant snow. — vm
The kaракурт spider has a shiny body, long thin legs, and an oval abdomen; adult females are 7–15 mm long, males 4–7 mm; young and some adults have red or reddish-orange spots on the upper side of their abdomen that may darken with age. — m24
The kaракурт builds nests in the ground, and bites occur only if someone accidentally puts a finger into its burrow or steps on it. — m24
Female kaракурts are more aggressive and venomous than males, and often consume their mate after mating. — m24
Experts advise not approaching within one meter of the spider, avoiding crushing or touching it; if a spider climbs onto a person, remain calm and let it crawl away or guide it using a stick or by leaning on a tree. — m24
