One of the most enduring myths about hot tubs is that they attract slugs. Fear not, for I am here to tell you that this is not the case.
Does a hot tub attract slugs? The truth is that slugs are attracted to stagnant water, which is just about anything but a hot tub. Hot tubs operate at a temperature over 100 degrees and constantly circulate water, which is not a suitable environment for slugs to survive.
The myth may have stemmed from the fact that slugs thrive where you do not want them to thrive – in your garden, the edge of sidewalks, and any place that is moist and damp.
The slugs are attracted to these moist, damp places because most species of slugs are sensitive to light.
These pests love moist environments, so they crawl right in when they see one.
In this blog post we will be discussing what slugs are, how you can prevent them from coming into your home or garden and more importantly – does a hot tub attract slugs?
Read on to find out the answer!
What is a slug?
Slugs are slow-moving, slimy creatures that feed on plants and animals.
They have an elongated body which tapers at both ends with the mouth in the center.
Slugs move by gliding along their bodies and secrete mucus as they go (this helps them to get around).
There are lots of different types of slugs, but all are considered pests because they do more harm than good!
Unique habitats for slugs include areas such as salt marshes in coastal zones where they can still reach fresh water and come into contact with algae that feed on their slime trails (which are created when they’re looking for tasty plants) which provide them with enough moisture.
These types of environments are usually only found between 30 degrees latitude north and south; but some species thrive at even higher latitudes – up to 50 degrees north!
The life cycle of a slug
Slugs can reproduce at any time of the year, but eggs require a moist environment such as wet leaves to survive.
Slugs are hermaphrodites and will typically mate in pairs for an hour or two before one slug crawls off to lay their spermatophore—a packet of sperm that dries on contact with air (or water) so it’s ready when needed later.
The other slug becomes female while the first one becomes male.
However if there is more than one potential donor then they may need to compete by depositing sperms from each partner’s gland into a shared receptacle which creates a plug until only one pair remains, who then fertilize their own eggs and create new slugs.
The eggs are laid either singly or in strands, and take about two weeks to hatch.
The slug then passes through three phases: the first is when it’s still living within its eggshell and absorbs nutrients from the egg; next as an ‘elater’, where it is sensitive to light but cannot move around much; finally as a true slug which can crawl freely (and will remain for most of its life).
In this form they eat dead plant matter such as leaves before molting into their final phase—a small shell-less creature called a naked slugs that feeds exclusively on decaying organic material like fungi or other decomposing animals.
Slugs are not identified by sex organs so all adults can be either male or female.
The life cycle of a slug is usually between four and eight years, although some can live for more years in certain conditions—such as when they are not eaten by predators or have enough food to eat.
Slugs have many predators such as cats, birds, snakes, foxes – all animals which enjoy feeding on them when given an opportunity.
The slug’s body starts to change as it nears its death, and becomes more transparent from a lack of food or water.
They will also start to have trouble moving around due to an inability to find any sort of nutrients.
How to identify slugs
The easiest way to spot one is in your hot tub – if you find some yellowish slime then it’s likely a slug has been there!
Other things to look out for include holes in leaves or flowers from where they’ve been eating, slime trails and the slug’s droppings.
Slugs like moist environments so check all surfaces around where you usually find them.
They also love eating algae on rocks and plants so look closely around water sources as well.
Are snails sensitive to temperature changes? The effect of heat on slugs
No, snails are not sensitive to temperature changes.
Snails are invertebrates and they do not have a very good sense of heat or cold.
They also don’t sweat, so their only way to cool themselves down is by withdrawing into their shells when the environment becomes too hot for them.
Snails regulate their internal body temperatures by opening and closing certain valves that control how much blood flows close to the surface of its shell which helps keep it warm in colder climates.
It does this because one side of the snail’s heart pumps oxygenated blood through an artery while at the same time pumping deoxygenated blood from an adjacent vein over the back part of its gills where gas exchange occurs with water molecules in order to get rid of carbon dioxide and take in oxygen.
The constant opening of valves cause the snail to adapt by regulating their body heat with a process like sweating, but they do not produce liquid through this method – instead it is from water molecules that are exchanged for gasses when close to the surface or veins near its shell which then evaporate into a cool vapor making them cooler inside at all times.
This adaptation has helped snails survive over 400 million years along rainforest watersides where sudden drops in temperature can happen on any given day.
As far as we know snails don’t feel pain during these changing temperatures because they do not have nerve endings around their bodies; therefore feeling no sense of warmth or coldness whatsoever. Snails also have a high tolerance for temperature changes.
Snails are indeed sensitive to the environment, but not as much so compared to other animals that share their habitat – plants and insects especially.
Why are slugs attracted to hot tubs?
Slugs love wet, moist environments so they’ll be drawn by a hot tub filled with water!
They can also hide under leaves or flowers where it’s damp from dew or rainwater – this is when you might spot them in your garden too.
Slugs usually want somewhere warm and dark (particularly at night) which means that if you’ve got an outdoor hot tub then they’re likely nearby!
Do hot tubs attract slugs?
Slugs seek dark damp places so they may come into contact with hot tubs where there is plenty of moisture hiding under leaves during daytime hours.
Being drawn by warmth, moist environments and plants, hot tubs attract slugs.
Slugs will not usually crawl into hot water as it is too hot for them to survive in and they can’t be attracted by the heat or smell of a hot tub.
These slimy creatures will make their way into your hot tub at night when it is cool and damp outside.
Typically there are no more than nine slugs per square foot – so even if you had 200 sq ft of wet surface area next to your hot tub that would only equate to 1800 slugs!
Slug populations usually grow at a slow pace anywhere from 10% per year.
Additionally, they have difficulty crawling up slippery surfaces like those found on smooth plastic which often cover your hot tub cover.
How do you get rid of the slugs in your hot tub?
If your hot tub smells like rotting eggs, chances are there’s a slug lurking nearby.
Install a hot tub cover that completely seals the hot water from the outside air – this also prevents slugs from getting in.
To keep these pests out of your hot tub, you should regularly check for holes in the hot tub cover and make sure that there are no plants nearby.
Frequently fill your hot tub with fresh water and add a slug-repelling chemical to it such as copper sulphate or diatomaceous earth – these chemicals will just need to be added at intervals of around every three months.
Ensure you regularly clean your hot tub’s filter so no algae or other decaying matter builds up on its surface which is what attracts them anyway!
And of course, keep an eye out for any signs of slug activity around your hot tub area such as slime trails on leaves and plants.
You’ll also want to keep an eye out for slime trails on the sides of your hot tub’s walls which could be from slugs inside!
Do Hot Tubs Attract Slugs? The Verdict!
No, hot water doesn’t attract them but moist environments do.
Hot tubs don’t attract slugs because hot water kills them.
Plants are more susceptible to being infested with slugs because they feed on decomposing matter and decaying plants.
Copper sulphate can help deter their presence in your garden by maintaining an organic environment.
Keep your garden organic with diatomaceous earth when possible to discourage their presence.
