The boys are back in town . Except , technically , they ’re not “ boys , ” but hermaphrodite land snails . Also , the “ township ” in question is three separate counties in central and southern Florida . Let ’s try this again : Giant African farming snails , a potentially annihilative invasive species , have re - appeared in three Florida county .
In Broward County , just north of Miami , one of the gargantuan gastropods was find earlier this calendar month . To attempt to halt the spread head of the mollusks , res publica official announced a ~5 square milequarantine geographical zone in Browardon Monday . Under the quarantine , channelise snails , soil , plant , compost , or building material is now outlawed — except with specific approving from the Florida Department of Agriculture and Consumer Services ( FDACS ) .
The fresh set up quarantine area conjoin two others antecedently designated across the state : One inLee Countyand another inPasco County . In each of these three zones , Florida officials are working to eradicate , not just corral , the snail . The state USDA section is using the toxicpesticide metaldehyde — which messes with snails ’ slime production — to attempt to kill the burgeoning population before they can kill everything else .

You see , giant African solid ground snail are ravenous eater known to consume more than 500 type of works including authoritative crops like dome , pea , cucumbers , and melons . If their preferred food source are n’t available , the snails will default to munch on just about anything else they can get their maws on , including ornamental plants , aboriginal botany , tree diagram bark — even the paint and stucco on construction , according tothe U.S. Department of Agriculture . The clenched fist - sized mollusks are aboriginal to East Africa . But in Florida , they pose a big terror to the res publica ’s farm industry and rude environment .
As a bonus , the gooey univalve often leave more than sludge trail in their viewing . They sway a parasite , call rat lungworm , known to cause meningitisin humans . If a person eats a escargot infected with rat lungworm , or unwashed vegetable contaminate with an infected escargot ’s slime , they can cease up ill . Though many mintage of slug and snail are capable of transmitting the sponger , elephantine African land snail can be peculiarly baffling because of how chop-chop they can spawn , their want of lifelike predators in Florida , and their predilection for crop plants . They ’re “ one of the most trespassing pest on the planet , ” by FDACS’sdescription .
Just a individual snail ( no Paraguay tea needed , thanks to the specie ’ specific biology ) is capable of laying yard of eggs in a year . They can scatter mile at a metre by hitching rides on vehicle or in transported M wastefulness . When conditions are n’t ideal for snail shenanigans , they can embark stasis , swallow in the ground for up to a year until context improve . In short : getting disembarrass of them is a challenge , yet it ’s one Florida has tackled before .

The state has antecedently dealt with giant African land snails on two occasions . The metal money was first enclose to Florida in 1966 in business district Miami . Through a $ 1 million program ( ~$3 million in 2021 money ) to ruin the animals and their eggs , the pests were hold eradicated by 1975 . But then , in September 2011 , the snail was re - introduced . It took another decade , and more than $ 23 million this time around , to make the state of the snails , agree tothe USDA . In 2021 , the metal money was once again uproot .
The gargantuan escargot population observe in Pasco County in 2022 is genetically unrelated to the snail eradicated from Miami - Dade County the twelvemonth prior , the federal office articulate . Broward and Lee counties ’ snails could be genetically discrete too . Although it ’s not just live where these latterly notice gastropod first came from , there are a few possibility . The USDA suggests the escargot might be favored releases — keeping giant African land snail as terrarium favorite is illegal , but masses still do .
The animate being may have also been advisedly bring over to be eaten . They ’re considereda prized foodin West Africa andhave been seizedby U.S. Customs and Border Protection before . late , officials interceptedsix live snails in a suitcase at the Detroit airdrome . Alternately , like many incursive species , Florida ’s newly find blighter may have made their way of life to the country through ball unintentionally carried on imported industrial plant matter . The fauna are wide enclose around the world and are find throughout China , India , Southeast Asia , and part of South America . Or , perhaps , Florida ’s preceding eradication attempts have n’t been quite as successful as they were assumed to be .
If you are a Florida resident and think you ’ve spotted one of the elephantine encroacher , snap a mental picture and contact FDACS ’ Division of Plant Industry . you may call the helpline at 1 - 888 - 397 - 1517 , or send an email to[email protected ] .
