How do I get rid of earthworms in my bathroom. My bathroom seems to be infested by earthworms. Every morning its unpleasant to see large earthworms in the bathrom. I pour a little disinfectant over the bathroom hole every night and keep it covered with a water filled bucket but still some how they seem to be creeping in from below or where ever I don't really know . My bathroom is otherwise very clean and also has no cracks or anything on any tiles. Its all renovated that way and I live on the 7th floor. The building is situated along the hillside and as such there's very heavy rainfall during monsoons and a variety of insects and worms are seen everywhere around during the season. Advice how do I get rid of these earthworms which are seen more or less throughout the year in my bathroom.
