Book excerpt: Common Household Pests: A Homeowner's Guide to Detection and Control is a companion book to the very successful Termites and Borers: A Homeowner's Guide to Detection and Control (also written by Phillip Hadlington and Christine Marsden). It follows the same practical, plain-English approach that has made its companion so popular. This book explores non-chemical as well as chemical means of control; includes many practical 'what to do' sections; promotes strategies of prevention as a first measure to achieve control; answers common householder questions about domestic pests; and it helps people to identify harmless and useful insects and spiders, as well as the disease-spreading and dangerous ones.
