(More tips from HGIC)

  • Don’t store firewood inside your home. Only bring in enough to burn at one time. Bark and other wood boring beetles may emerge inside the home.
  • Fruit flies can be a problem when fruits and vegetables are allowed to sit for long periods on kitchen counters. Use up your produce quickly.
  • Store leftover nuts from the holiday season in the freezer and store dried fruit in your refrigerator to avoid pantry pest problems (PDF HG 67).
  • Indian meal moths are a common problem of grains and grain products, cereals, bird seeds, dried pet food, etc. You may see adult moths flying, larvae crawling or webbing. Remove the source of the infestation and clean all jars and containers that are affected. Always check bulk foods prior to purchase for signs of meal moth infestation.
  • Cluster flies resemble large houseflies and may suddenly appear around window or lamps in the fall, winter or spring. They occupy attics or wall voids and become active on warm, sunny days. They are sluggish flyers and do not eat garbage. Prevent their entry by sealing up all small holes and cracks around the outside or your home. (PDF HG 26 Flies in and Around the Home)
  • Avoid storing pesticides over the winter in sheds and garages. Cold temperatures can cause these materials to become ineffective. If you have questions about the efficacy of your pesticides call the manufacturer, using the phone number listed on the label.
