Tips on how to keep slugs out of your garden and how to rid of slugs that have all ready invaded.

Have those slimy creatures with names to fit their appearance, or what are better known as slugs invaded your garden? Well, hopefully the

proceeding tips will help you rid of the ugly beings.

Below you will find different ways to keep out or get rid of the pests, with inventive names such as: Drunken Slugs, River of Salt, Sticky

Situation, and Humanitarian. There is a way for every type of person.


Drunken Slugs


Use this method only if you’re 21 years old or over, or if you have permission from your parents.


Materials:

tuna fish cans (or cans like them, cat food cans work just as well. How many you will need depends on the size of your garden), any type of

beer (slugs don’t care whether or not it’s good. Here’s a way to get rid of any skunky beer too), and a trowel (or a child’s beach shovel

will work as well)


Procedure:

1. Open the tuna fish can’s and use them for lunches or dinners or whatever and then rinse them out very well.

2. Go out to your garden and dig holes evenly spaced out in your garden with your trowel that will fit the tuna cans.

3. Place the cans in the holes that you dug, so that the top of the can is exactly level with the top of the hole.

4. Open a can of beer and pour it into the tuna cans, so that they are filled about ½ or ¾ of the way full.

5. Leave the traps to do their duty.


Results:

What will happen is that when you go out the next day to check your traps, you will find drowned slugs in your traps. You see, slugs are

attracted to the smell of the beer and will move to find it. When the get to the trap they will crawl inside to take a drink. Even a slug

mouthful of beer will cause them to become drunken and disoriented enough, so that they cannot find their way out of the can and then they

will drown.


River of Salt

May create problems if it rains due to the amount of salt required


Materials: large container of salt, cut pieces of cardboard (enough so that it lines the outside of your garden), plastic wrap, and a trowel


Procedure:

1. Cut out the pieces of cardboard, so that they have a bottom and two sides and no tops and holes on the ends (i.e. end view).

2. Wrap the cut pieces of cardboard in the plastic wrap to keep the moisture from the ground from ruining the cardboard.

3. Go out to your garden and dig trenches with your trowel all along the outside edge of your garden that are wide enough to fit your

cardboard (make sure you have enough cardboard to fit the length of your trench).

4. Place the cardboard into the trench so that the top of the sides are level with the top of the trench.

5. Fill your cardboard trench with salt.


Results:

Anyone who can remember back to their childhood and poured salt on slugs to watch them dry up and shrivel, knows that salt is not a slugs

friend. Therefore, your salt trench will provide a good barrier from the slimy pests because if a slug tries to wade through it, they will

cease to exist.


Sticky Situation

requires getting near the slimy beasts


Materials:

black plastic (like garbage bags), and stakes or long nails


Procedure:

1. Go out to your garden and place the black plastic around the outside of your garden.

2. Stick the plastic in place by staking or nailing the ends down.


Results:

When a slug goes to enter your garden on a sunny day it will have to ooze its way acroos the black plastic. On a sunny day the plastic will

be so hot that it will heat the slug's slime and the slug will then become stuck to the plastic, so the next day you can go out and pick up

the plastic and simply throw the pests away.


Humanitarian

Good for naturalists and humanitarians


Materials:

money, transportation, and a trowel


Procedure:

1. Find a way to get to your nearest garden/plant store.

2. Go up to a salesperson and ask them where they have the plants that have been engineered to keep away slugs (yes, they actually have

certain flowers and plants that have been genetically engineered, so that slugs are not attracted to them).

3. Go to the cashier and make your purchase.

4. Go home.

5. Plant your new purchases.


Results:

This way may be more expensive, but if you are a person who hates to harm living creatures, it will give you more peace than the other ways.


Your garden should now be relatively safe from slugs. On the other hand, there are other pests that can invade your garden. If there are

other pests in your garden, consult your local garden store professionals. Happy gardening!






Ugh Slugs!!

http://www.bachmans.com/tipsheets/gardening_problems/ughslugs.cfm

They're everywhere! Slugs are a problem in gardens almost everywhere that there is shade, moisture and plants. If you are not familiar with

these creatures, you can think of them as snails without shells. Slugs are actually mollusks and are not even related to insects. While there

are many types of slugs around our area, we are lucky to only host some of the smaller varieties. We could be as unfortunate as those folks

out in Eugene, Oregon, known as the Slug Capital of the World, where it isn't uncommon to come across slugs that are 6 inches long and bright

yellow.

Slug Biology 101
Understanding a little about slugs and how they live can help you deal with them in the garden. Slugs have very soft, exposed bodies, and

exude a slime that they then slide across. Slugs will bother a wide range of plants, but they have their favorites. Unfortunately for those

of us in Minnesota who love hosta, slugs do too. They go after them like they're slug candy. Since slugs have soft, exposed bodies, they

prefer cool, moist areas. They avoid sun because they may dry out, so they feed largely at night when it is cooler and more moist. To

understand how slugs multiply so quickly, it helps to know that they are hermaphrodites, creatures that have both male and female body parts.

That means that even when there aren't enough slugs around for much dating and mating, they can manage it all by themselves. Slugs lay eggs

that look like clumps of tiny gelatinous pearls, each about the size of a pin head. The eggs are deposited in the soil where they may hatch

in a few weeks or lay dormant for months until there is enough moisture. Slugs take about a year to mature and overwinter in the soil. Their

natural predators are toads, snakes, birds, turtles, ducks and even chickens!



Identifying Slug Damage in Gardens
The most obvious sign, of course, would be to find the creatures. Unfortunately, that's not as easy as it sounds. Because of their soft

bodies, slugs tend to hide during the day when you might be out in the garden. Slugs do their work at night. Taking a flashlight out at night

to look for slugs is one way to check for them. An easier way to find slugs is to look for their damage or trap them. There are several ways

to identify slugs so you can see how much of a problem you have.


Most gardeners don't know they have slugs until they see the damage. Slugs are rasping creatures and damage plants by scraping layers off

leaves, flowers or any other soft tissue. Their presence is usually easy to confirm because they leave a shiny trail wherever they have

traveled. On many plants, especially those with larger thick leaves, slug damage is distinctive because they make irregular holes with smooth

edges. The holes are usually larger than a pencil eraser and smaller than a quarter. The damage also tends to be within the leaf blade

instead of along the edges. Most other chewing insects will eat from an edge and take much larger areas. Severe damage on a hosta will leave

the leaves looking like swiss cheese. On some plants, they seem to go for the nice, tender new growth. That is common on impatiens and

marigolds. Another slug favorite is ripening fruit–especially soft fruits that are close to the ground, like strawberries and tomatoes.

Options for Dealing With Slugs
There are several ways to deal with slugs in the garden. These include a variety of ways to create inhospitable environments, such as

trapping or poisoning the slugs and creating barriers. Sometimes it will take a combination of methods to establish control. Research is

currently being done to test a type of nematode that seems promising against slugs. There are actually lots of folk remedies floating around

in gardening books and magazines that may work, too. Always use caution. Some recommendations (such as tilling the soil several times) will

actually do more harm than good. If you have a strong stomach you can always pick off the slugs and dispose of them. Early morning is best.


Here are some details on the most effective and popular methods of controlling slugs:

Creating an Inhospitable Environment
• Think sun. Slugs avoid any place sunny.
• Encourage toads and snakes to visit your garden.
• Keep the surfaces surrounding your plants rough and dry.
• Clean up any plant residue and other places slugs may hide during the day.
• Grow varieties of hosta that are more "slug resistant," like those with puckered or thick blue leaves.
• Avoid composting slug infested plant material.



Trapping
• Create a slug pit by inserting a tuna can into the ground where you suspect a slug problem. Make sure the edge of the can is level with the

ground, and fill it with about an inch of non-poisonous liquid bait. Slugs are drawn to yeasty smelling liquids, such as beer. An inexpensive

alternative to beer is to make combine a quart of warm water, a packet of dry yeast and a little sugar, molasses, or honey. Give the mixture

15 minutes at room temperature to activate the yeast. Keep it in the refrigerator, and use it later to rebait the traps. Once attracted to

the traps, the slugs fall in and drown. Traps should be checked every day or two, emptied and the bait refreshed.

• Slugs are hide during the day in the nearest cool, dark place. Lay down a shingle, smoother side down, where you suspect slugs. Pick it up

the next day and scrape them off the bottom of the shingle. Another option is a section of wet newspaper, still folded. When you pick it up

the next day, you can simply throw it away, slugs and all, and put down a new section the next night. Overturned flowerpots or saucers work

as well.

Barriers
• Diatomaceous earth (DE) can be spread around an area or a plant to deter slugs from reaching it. DE works because it is actually flat,

sharp edged crystals that shred the slugs' soft undersides, causing them to dry out. DE does have to be renewed after a rain.

• Put down a layer of sharp sand. It stays in place and stays effective. Unfortunately, this option isn't very attractive.

• Copper strips are available in some garden centers and by mail order. Slugs will not cross copper. This is one method that works even after

it has rained.

Baits/Poisons
• There are two basic types of bait: One type is made with iron phosphate (Slugoä), and is safe and effective when used as directed. Although

it may seem more expensive, you use a lot less of it in the long run, making it an affordable alternative. Another form of slug bait has been

around for years and contains the chemical metaldehyde. This bait comes in pellets, powders and a gel. Metaldehyde-based baits have several

serious drawbacks. They need to be reapplied frequently and may also poison some of the natural predators of slugs, such as toads, snakes and

birds. Pets and small children may be attracted to the poison pellets, too, Use them carefully as a last resort. Follow all directions and

cautions.

Slug Control in the Garden
http://gardening.about.com/od/gardenproblems/a/Slug_Control.htm

Slugs hide under leaves and do a lot of damage in the garden, before you even know they're there. Here’s what some readers recommend. What

are your tips for getting rid of and controlling slugs in your garden?

•I used the beer method - but in place of saucers I reused bottles. Just drink the beer and leave a bit in the bottom - lay the bottle on its

side and press into the ground so the opening is atop of the soil line. I have seen quite a few drowned in the bottle this way when I checked

the following morning. So this is working for me. The other thing I tried was directly spraying the slugs (at night when they are out eating

my garden goods) with a strong solution of salt water. I water the next day to minimize the damage from the salt on my plants. A local farmer

told my husband to sprinkle snuff around the plants for slugs - I will try that next. I did read about crushed egg shells (you grind them

into a powder) and sprinkle about - I did that too. So far the damage has been minimal with these methods. Submitted By: Becky Bumper-Crop

•I have 2 methods for dealing with snails & slugs: one is crushed egg shells, which the snails and slugs do not like to cross since they cut

up their bodies. I collect egg shells in a separate container, put them in a plastic bag, and step on them to make jagged pieces (not too

large, not too small). Spread evenly around susceptible plants and re-apply as needed.
The second method uses copper, which apparently gives off a light electric charge to our slippery friends. A copper wire around the perimeter

of hostas just as they begin emerging works wonders. There is also a copper mesh on the market for taller or larger applications, but I have

not used it myself. I use copper around perennials and egg shells in the vegetable garden where things get moved, replaced, and re-planted.

Since I have begun using these methods, my neighbour has been complaining of an increase in slugs and snails! Go figure ... Submitted By:

•I use crushed egg shells. Beer tends to attract every slug in the neighborhood (at least it seems that way!). Be sure to rinse out and

microwave the shells for a minute or two to sterilize them or you will have rodents coming to your garden. The sharp shells will cut the

slugs and they will die. I sprinkle them around my hostas and anything else that shows signs of slug damage. Submitted By: Cynthia

•Place beer bottle or similar with about half cup of beer therein on its side in garden, opening level with ground. Recently trapped 52

juvenile slugs in one night. Submitted By: Bryan

•This kills the little suckers! 1 and a half cups each of water and ammonia and 2 tablespoons of Murphy's Oil Soap. Put in a good spray

bottle shake and start spraying. Submitted By: Linda

•I have used small cans and put beer in them and to my surprise it does work. as long as the tins don't tip over. One night I put 4 empty

tuna cans in my garden and poured in the beer, and by morning I bet I had over 50 slugs in the cans. Even though it didn't totally get rid of

the slimy guys it did help. Submitted By: Sue

•Copper Shocks/Deters Slugs With Success I have a cottage garden that is vulnerable to forest/woodland behind my property, therefore, there

are countless slugs/snails who love to visit my garden, but they don't hang around for too long now because they would starve. After much

research, I decided to build a raised bed & surround it with bendable copper piping, which can best be described as "boarder control". I also

purchased copper ribbon & glue gunned it just beneath the rims of all of my planters/pots. These two particular methods of using copper is

highly successful. All other methods mostly failed, my beloved collection of Dahlia's & Hostas are thriving!!! Submitted By: Janet

•One morning I had over 50 slugs in my garden. Each morning before leaving for work, using gardening clippers (shears) I cut them in half and

threw them in the garbage can. Some there were almost none left and each year there were fewer and fewer to deal with. Submitted By: Barbara




Low Tech Method
http://pestcontrol.about.com/od/controllinggardenpests/a/SlugControl.htm

Hand picking of slugs is still the primary tool in any slug-fest. Lay boards, overturned ceramic pots and spent grapefruit halves in the

garden soil before dusk. Sprinkling water around the slug shacks will make them irresistible to passing snails. In the early morning, tip-

over the boards, pots and grapefruit and drop the resting slugs into a coffee can or yogurt container. (In my own experience, when I dropped

live slugs into a pail, without a lid, thinking that they would drown, they simply crawled out eventually. Only when I began adding a few

drops of dish soap to the water, would they succumb and die. So I just pour the slugs and water onto the compost pile.)

Also, the snails can be recycled into the farm pond as fish food, or their slime can be used for chafed skin.

Traps
Dig a shallow depression in the garden, sink an aluminum pie pan so that its lip is at soil level, and fill with beer, or a soup of yeast,

molasses and water. Slugs will crawl into the plate, not be able to escape and will drown. Note: this method works best if your garden is

fenced or if you do not have a pet that may drink the bait liquid.

For a more pet-proof trap, cut a 1” hole in an empty coffee can, sink the can into the ground so that the hole is at soil level, fill with

bait liquid and replace the can lid.

Sticky traps can be laid along slime trails, however, they should be used sparingly as they also snare lizards and frogs, both of which are

very beneficial to the garden.

Pellet Baits
Iron Phosphate pellets, available at markets, hardware and garden centers, can be scattered in the garden, killing snails about 6 days after

ingestion. Although company advertisements claim complete safety for pets, wildlife and humans, care should be taken not to expose pets or

children to the pellets.更多精彩文章及讨论，请光临枫下论坛 rolia.net
