  • December 11, 2007
  • Why is Rodent Control so Important ?
  •  Loss & Destruction of food  1982-reported 42M tons of food ($30B); 1/5-1/3 of world’s food supply does not reach table  Gnawing Damage  2% of daily activities; incisor growth is continual, Moh’s scale (5.5), estimate ½ of fires declared undetermined origin from rodents  Human Disease & Allergens  Harbor / transport disease, pathogens, microorganisms, ectoparasites  Loss of business  Word of mouth, public health posting
  • What are the three most common rodents Orkin deals with?
  • 3 most common rodents  Norway rat  Roof rat  House mouse  Honorable mention: shrews, voles, deer mice, lemmings, jumping mice
  • House Mouse  Originates from Central Asia  #1 rodent pest in most parts of the world  Smallest of the 3 – about 2-3½ inches long (head and body)  Weighs about 14-28g  Gestation: 18-21 days  Avg of 5-6 mice/litter  Lifespan up to 2yrs  Breed rapidly, tolerant of many conditions, adjust quickly to environ
  • Norway Rat  Originated in Central Asia  Large – head and body about 16 inches long  Avg weight 340g  Gestation: 21-25 days  Avg of 6-12 pups/ litter  Lifespan 1yr  Neophobic nature
  • Roof Rat  Also known as black rat, ship rat  16 inches long  Avg weight 226g  Tail longer than the body  Sleeker appearance  Prefer elevated areas/ more elusive  Tropical / costal areas predominantly
  • Why do rodents infest structures?
  •  Colder weather drives them indoors  Changes to their natural habitat  Food and water availability  Population  Shipped with product Why do rodents infest structures?
  • What are the different ways of identifying rodent infestations?
  • Identifying Rodent Infestations  Gnawing Damage  Droppings  Rub Marks  Damaged Products  Burrowing  Nests  Odor
  • Gnawing
  • Rub/ Grease Marks  Oil and dirt rub off of a rat’s coat when it rubs against things. These grease marks build up in often used runways and soon become noticeable. These marks are commonly found along wall/floor junctions, on pipes and ceiling joists, and on sill plates.
  • Damaged Product
  • Burrowing/ Nesting
  • The Five Steps to Control 1. Seek out the source of infestation 2. Identify conducive conditions for the existing and any potential infestation 3. Communicate with the customer to resolve the infestation 4. Proper use of control devices 5. “Documentation”
  • Rodent entry areas  Openings around utility lines that enter the facility (i.e. water lines, air conditioning ducts, drain pipes, vents, etc.)  Spaces beneath doors  Broken windows and unscreened vents  Check roofs to see that fascia boards and shingles are fastened tight and sheathing and flashing is complete  Check chimneys for entry areas
  • Rodent survival needs  Food  Water  Shelter  Warmth
  • When seeking the source and identifying conducive conditions, it is often most helpful to think in terms of the rodents’ requirements for survival first. Survey the building and identify all of the areas where food is available. A rodent’s nest will usually have food that is nearby and accessible.”
  • “Control Methods”  Glue boards  Mechanical traps  Exterior rodent bait and bait stations  Interior rodent bait and bait stations
  • Glueboards
  • Mechanical traps
  • Exterior rodent bait and bait stations
  • Interior rodent bait and bait stations
  • Structure Infesting Flies
  • House Fly Biology - Most Common of all flies; - Have 4 longitudinal stripes on the pronotum or thorax; - Large, bulbous, multi-faceted eyes; - A pair of transparent wings; - Adults range from 4 to 7.5 mm in length; females are generally larger than males -Why concerned? - Attach themselves to garbage or rotting material; -Transmit a wide variety of diseases; - Can move quickly from waste and unsanitary conditions to food or utensils;
  • House Fly Tips for Prevention & Control All Flies Except Drain Flies - Clean all drains and sink areas - Replace broken windows and screens - Reduce the presence of ripe fruits and vegetables; place them in a refrigerator or a paper bag - Create an air current to prevent them from landing in their favourite areas - Close the lids on all garbage and waste containers
  • Blow or Bottle Fly Appearance -Blow flies are often metallic in appearance, - Have feathery hairs on the terminal antennal segments of the males. - Adult blow flies have sponge-like mouth parts, while maggots have hook-like mouth parts.
  • Blow or Bottle Fly Behavior, Diet & Habits - To date, there are approximately 80 species of blow flies in North America. -Blow flies are attracted to decaying meat and are typically the first organisms to come into contact with dead animals. - The meat of dead animals is essential for larval survival and growth. - They are also attracted to plants that give off the smell of rotting meat and as such, can be a pollinator for those plants.
  • Blow or Bottle Fly Signs of a Blow Fly Infestation -The most common signs of blow flies are either the adults themselves or their larvae. - The adults may be seen resting on surfaces or buzzing around potential food or odor sources. - The larvae may be observed when they crawl out of the breeding material to pupate.
  • Cluster Flies Biology - Cluster flies, also known as attic flies, are household pests. - Adults measure 8 to 10 millimeters in length and have light and dark grey-checkered abdomens. - Cluster flies are slightly larger and darker than the common housefly and move more sluggishly. -They appear on the sunny side of the structure in heaviest concentrations in late fall and early winter, as they seek warm locations in which to live during cold months.
  • Drain Flies Physical Appearance: -Drain flies are very small (typically 2 to 5 mm in length), light grey or tan colored flies with short body and leaf shaped wings. - The body and wings are covered with small hair which gives it a fuzzy appearance. - Wings are too large when compared to the body, drain flies fold their wings in a characteristic roof like pattern.
  • Drain Flies Behavior & Habitat: - Drain Flies are typically nocturnal insects and are associated with damp habitats. - They are not very good at flying, they fly in a jerky, irregular pattern. - Adults can be spotted resting on walls and ceilings of the infested areas. Another important thing about them is that they do not bite.
  • Drain Flies How to Get Rid of Drain Flies 1. Keep the drains clean and clog free. 2. Make sure that there is no stagnant water in your bathroom or kitchen. 3. Occasionally spray IGR (Insect Growth Regulator) in your drains. IGR spray prevents the drain fly eggs from breaking out of the larvae stage and hence can greatly reduce the chances of any future infestation.
  • Bed Bug Control Male Common Bed BugMale Common Bed Bug
  • “Bed bugs probably received its name by being historically know as a bloodsucker that feeds on humans sleeping in bed at night. The bed bug primarily attacks humans but can feed on any warm- blooded animal such as birds, mice and pets.”
  • “What is causing an increased bed bug infestation across Canada?”
  • “There is no definite answer to the question” However, it is believed that because people are traveling internationally and much more frequently they are likely to encounter more insects, such as bed bugs. Therefore a more reasonable explanation is that bed bugs are likely to be found in dwellings with a high rate of occupant turnover. Another reason may be the reduction of residual insecticide spraying by pest control companies and home owners.
  • “However, bed bugs are not just transported by people.”
  •  Used furniture  Luggage  Clothing  Airplanes
  • “Identification”  Adults are about 4-5mm” long  Flat (nearly as wide as long)  Oval in shape (compared to most other insects)  Mostly brown in color or reddish brown after feeding)
  • “Description” “A bed bug is small. It’s about the size of a pencil eraser. It hides during the day and comes out during the night to look for food. As they feed, they turn a dark red and can swell to the size of a ladybug”
  • What do they look like? Immature adult Adults Nymph: miniature of the adults Engorged adult
  • What do they look like? Oval, flatten bodyShiny, reddish to brown body becoming bright red after blood meal Pointed piercing mouth part 4-5mm long No functional wings
  • “Biology” “Female bed bugs will lay 1-5 eggs per day and can lay over 500 eggs over a lifetime. Each bed bug will molt its shell five times as it grows and a blood meal is required for each molt. If blood meals become scarce, bed bugs can slow their life process until a blood meal is found. Under ideal conditions, the egg to adult cycle takes about 21 days. With normal feedings, the adult bed bug lives about one year”
  • Sample Infestation Scenario 48
  • “Do Bed Bugs transmit diseases?” “Although bed bugs may carry different diseases, transmission to humans has not been proven”
  • “What are some of the signs of bed bug infestation?”
  • How you know when you have an infestation Small brownish or reddish spots on bed linens Fecal / blood spots on harborage sites
  • Live bedbugs, eggs, and castings
  • Inspection sites  Mattress and box springs of beds  Any crack and crevice in the bed frame  Behind wall hangings  Night stands  Stuffed furniture  Under and behind baseboards  Behind loose wallpaper  Light switches  Door and window frames
  • “Treatment”  Steam treatments  Vacuuming  Pesticide  Prevention and Education
  • “What to do with bedding or clothing?”  Have cleaned by a professional cleaner  Wash in high temperature  If laundry is brought off site do not return with it in the same bag
  • The initial treatment should be followed up with an inspection 7 to 10 days after the initial treatment
