Slugs like damp situations and live under stones. Unlike snails, which hibernate during the winter by sealing themselves in their shells, slugs are active throughout the year.
Slugs are mostly found in the garden where they can be a real problem for gardeners, munching away at their plants throughout the year but they are often considered a greater problem in the house.
Slugs in the home present little health problems to humans though they may carry all sorts of viruses and bacteria. They may find their way into your vegetable rack and begin to eat your vegetables, consequently spoiling them. Slime trails across the floor are unpleasant, unsanitary and unsightly – and it is horrible to tread on a slug, particularly if you are not wearing anything on your feet! Since slugs satisfy mostly at night they are often found in your home first thing in the morning.
There are two main ways to prevent slugs entering your home – one is to create a obstacle of some sort – a copper strip or something that slugs do not like cross, such as dry grit, crushed eggshells or ash. The other is slug pellets, salt, or other chemicals. The caffeine in coffee has also been found to keep slugs and snails under control. These do, however, present the problem of poisonous materials that children and pets may find and it might be difficult to encircle your house with eggshells or ash!
The other is to block all method of entry.
Slugs can go into your house by holes under doorways, in gaps between bricks and by damaged fascias. These entry points should be discovered and confined with cement, plaster or wood.
A more shared entry point is the holes in the airbricks located around your house. These are vital elements of your house, allowing air to go into the cavity walling so keep it aired and damp-free and so it is basic that these holes are not confined.
The solution is to cover the airbrick with a fine wire mesh or buy a purpose-made wire mesh cover that can be easily fitted over the airbrick. This will nevertheless allow air to pass by the airbrick but the fine mesh will prevent slugs entering.
Preventing slugs from entering your home is a much more humane method of slug control than using chemicals – leave it to the gardener to solve the slug problem in their domain!
