How To Control Woodlice

The Woodlouse Problem

Woodlice, which are not known to transmit disease, may cause superficial damage to decorations and possibly furnishing in your home. You wil have noticed that they leave a stain if you crush them on the carpet. Normally, damp areas attract woodlice but in most cases, these crustaceans enter your home by accident and are found just wandering around. Woodlice will die in most home environments as they are damp lovers and are soon dehydrated by our warm indoor environments.

Woodlice (order Isopoda) can be found throughout the UK and there are three main species, Armadillidium Vulgare or Pill Wood Louse. Oniscus asellus the Common Wood Louse is the largest of the woodlice found in the UK being up to 15mm in length. Porcellio scaber is narrow with dull, rough segments. The exoskeleton is divided into segments and the woodlice have up to 14 legs.

Woodlice feed on mould growth, leaves and rotting wood, they are known to damage wallpaper which may be due to feeding on minute mould growth on the paper causing incidental damage. Woodlice may be found anywhere in your home but most commonly will be found on the ground floor having entered via poor seals around doors and windows or through air vents. Woodlice can however live in roof voids and in damp bathrooms and toilets.

If you have done enough reading, you can buy a WOODLICE CONTROL PACK for treatment of the average sized home, complete with instructions.

Woodlouse Control Measures (Indoors)

Woodlice are easily eliminated with insecticidal sprays and dusts. It is adviseable to wear suitable protective clothing when dealing with any pest, masks, goggles, coveralls and gloves are available from the Pest Control Direct website.

When applying insecticidal powders and sprays, keep children and pets away from the area until surfaces are totally dry. Apply powders to areas out of reach of children and pets.

Pesticide sprays such as PRO-ACTIVE C FOR WOODLICE, are very effective in killing woodlice however, treament indoors alone will probably not control the problem totally. Woodlice originate from outdoors and to gain good and effective control, you will need to take action outside the home in addition to internal control measures.

Ensure that you eliminate damp areas in your home by either heating more effectively or stopping leaking taps or water dripping through poorly fitted worktops, baths and sinks. Seal as many gaps as you can find with a good sealant and ensure door draught excluders are not damaged.

Outdoor Control Measures

Preventing woodlice from entering the house is your target result. Remopve vegetation from around the perimeter of the home. Woodlice thrive on vegetable and organic matter so removing any such matter from around the perimeter will help. Re-point walls if there are gaps in the pointing as woodlice are well known for living in old garden walls. If you are really serious, you may want to check your gutters as, debris in gutters provides good food and harbourage for the wood louse.

Apply an insecticidal powder such as RENTOKIL ANT AND CRAWLING INSECT DUST to wall bases around the property, into airbricks, firstly checking that the airbrick does not lead into a cupboard or directly into the home, most airbricks lead to the subfloor area where woodlice are happy to live and are able to access your living area from there.
