rotate use of different products on the same property to reduce the likelihood that pests will develop a tolerance to a particular type. Before applying any spray pesti- cide treatment, send kids and pets outside to play or to another room in the house. Apply the product along baseboard areas, around doors and windows, and to any problem areas. Allow it to completely dry before return- ing to the treated area. Some products, such as foggers, require you to leave your home altogether. If you are not comfortable with the chemical pollutants of pesti- cide, then consider one of the newer electronic pest repellers. Companies such as Radarcan offer a variety of repellers that emit ultrasound waves that are unbearable to pests such as mice and cockroaches, driving them away from the area for hundreds of square feet. It eliminates the need to set and empty mousetraps and provides an alternative solution for allergy sufferers or people with respiratory problems. SEAL ALL GAPS WHILE YOU CAN
A friend of the EHT staff, Keith Lively, contracted construction of a new house and decided to do much of the work himself. One night after the house was framed and the sheathing installed, he noticed something as the sun set: light. Lots of light shone throughout the house framing and sheath- ing panels. Anywhere light can pass, so can unconditioned air, so Lively took the opportunity to seal his new house before the insulation and drywall were ever installed. Every pipe, seam and joint got a dose of caulk/sealant or expandable foam to keep air transfer low and energy bills to a minimum. If you ever build a home, or add a wing to your existing one, you should do the same and seal all the gaps while you can reach them.
