1 Physicians for Social Responsibility-Los Angeles Integrated Pest Management Cockroaches/Bed Bugs

2 The link between housing and health 2

3 What is a healthy home? 3

4 What is so important about a healthy home? Housing conditions can affect health both directly and indirectly. Children spend close to 80-90% of their time indoors. 4

5 Health effects that are associated with housing conditions Respiratory infections Asthma Injuries and burns Allergies Poisonings Neurodevelopmental and behavioral problems Cancer Death 5

6 Steps to a healthier home Keep the Home/Building: Dry Clean Ventilated Safe Contaminant-free Maintained Pest-free Today we are going to focus on keeping the home pest-free. 6

7 Why Pest Free? - the health effects of pest exposure More than just a nuisance-pests in the home are a health issue… Cockroaches, flies, fleas, rats and mice carry disease. Roaches and house dust mites can make allergies and asthma worse. Roaches can also bite and crawl into childrens ears. 7

8 Why Pest Free? - the health effects of pesticide exposure Acute health effects of pesticide exposure include: Eye, nose, and throat irritation Skin rashes Nausea and Asthma attacks. Long-term effects of pesticide exposure include: Cancer Birth defects Central nervous system damage Respiratory damage and Endocrine disruption. 8

9 Drawbacks of Conventional Approach to Pest Control 9 Potential liability for property owners and managers (tenant injury from pesticide exposure). Ineffective in controlling pests. Little or no communication between tenant, property manager and pest control operator.

10 What is the alternative? -Integrated Pest Management 10 IPM Methods emphasize: Pest Exclusion- block pest entry points, hiding places and passages; Reduction of pest food and water sources- repair leaky plumbing, proper food storage and disposal; and Control existing pests with low-risk control measures- boric acid, baits, and cleaning with borax. Least-toxic pesticides are used only as a last resort…

11 How is the pest getting into your building? 11 Cracks around baseboards and under doors. Holes in walls where plumbing or heating ducts come through. Doors or windows left open or damaged screens. Unscreened vents.

12 Find their path and block it! 12 Install screens on windows and doors. Install door sweeps. Caulk cracks and crevices in walls, floors, around baseboards and windows. Seal holes around pipes.

13 Reduce Pest Food and Water Sources 13 Pests can find food in: Trash cans Appliances Unsealed food on countertops Dirty dishes Pet bowls Pests can get water from: Leaky roofs Leaky plumbing (toilet/sink) Air conditioners Sink and tub drains Standing water in pet bowls/houseplants

14 14

15 Control Pests with Low-risk Measures 15

16 Take Home Message Pest Control = Shared Responsibility 16 Effective pest control requires a partnership between the building owner/property manager, the tenant, maintenance staff and the pest control operator.

17 Review Questions There are seven steps to a healthier home- name three of them. True or False Cockroaches can make asthma and allergies worse? Name two health effects or symptoms of pesticide exposure. What are three methods of blocking pest entry points to the home? Name three places in the home pests can find food or water. True or False IPM advocates the use of pesticides prior to blocking pest entry points and reducing food and water sources in the home. 17

18 -What they are -What they eat -Where they live -Prevention and control Cockroaches

19 What is a Cockroach Lives in areas where humans provide food and water Active at night (If you see cockroaches during the day, the infestation is serious) Many eggs in each egg case Nymphs look like small version of adults 19

20 German Cockroach Medium size (3/4''), bronze, with racing stripes behind the head Found everywhere, but likes warmth, moisture, and darkness Reproduces quickly Mother carries eggs to term even if she is dead Eats almost anything 20

21 Signs of Cockroaches Live cockroaches Dead cockroaches Frass Egg Cases 21

22 Where cockroaches live Anywhere in a building Prefer spots near water but also need food and warmth In cracks and crevices where their bodies touch surfaces above and below 22

23 What cockroaches eat Crumbs Grease Trash Cardboard glue Just about anything 23

24 Where cockroaches find water Sinks Counters Floors Pet bowls Leaky pipes Refrigerator drips AC units Shower stalls 24

25 Whats the problems here? -How would you fix it? 25

26 IPM for Cockroaches Inspect: What kind? How many? Where are they living? Prevention and Control Sanitation Exclusion Least toxic pesticides 26

27 Inspect Where are they hiding? Look for evidence where cockroaches would find food, water, or a hiding spot: up, down, behind, and under. Monitor By placing sticky traps near areas where cockroaches might travelat corners and near warmth, food, and water. Traps help find cockroaches when and where people cant. 27

28 Prevention and Control - Sanitation Eliminate hiding spots, food, and water available at night by Reducing clutter Throwing away dead cockroaches Cleaning frass and areas where there were cockroaches with soap and water Cleaning with Borax (washing floors in kitchen/bathroom) 28

29 Prevention and Control -Exclusion Seal or fix cracks, peeled wallpaper, or holes that cockroaches could get through with: Screens on windows and doors Door sweeps Silicone caulk Copper mesh 29

30 Prevention and Control -Least Toxic Pesticides -Exclusion and Sanitation first! -Maintenance staff and residents should never spray pesticides!! Bait Stations (roach motels) The bait needs to be the only food in the areasanitation first! Wont work if contaminated by strong- smelling cleaners or other chemicals, pesticide sprays or foggers, or nicotine from cigarette smoke. 30

31 Prevention and Control -Least Toxic Pesticides Insecticidal Dusts-Boric Acid Effective if used correctly. Light dusting instead of piles. Use in walls before fixing them. Under and behind cabinets at turnover or when making large repairs…but clean first! Because dust can become airborne Respirators must be worn when applying and Ventilation Systems should be turned off! 31

32 Prevention and Control -Insecticidal Dusts 32 Incorrect use of insecticidal dust

33 Never Use Sprays and Foggers 33

34 Review Questions True or False cockroaches are most active during the night. What are two signs that a home is infested with cockroaches? Name three places in the home where cockroaches can find water. What tool is used to monitor for cockroaches in a home? Name two ways to eliminate cockroach hiding spots and/or food and waters sources in the home. 34

35 -What they are -What they eat -Where they live -Prevention and Control Bed Bugs

36 What is a Bed Bug A blood-sucking insect Most active at night Usually feeds at night Bed bugs do not transmit disease, but they cause secondary infections after people scratch their bed bug bites; and result in stress, loss of work, loss of sleep, and financial burden. Adult bed bug feeding on human 36

37 Bed Bug Behavior Hide in cracks and crevices, often in groups. Hitchhike on bags, furniture, wires, or pipes. Cannot fly, jump, or burrow into skin…they crawl. 37

38 Signs of Bed Bugs Bites Blood spots Shed skins Dead bed bugs Live bed bugs 38 Adult bed bug and droppings on mattress. Bed bugs and fecal spots.

39 Signs of Bed Bugs Shed skins 39 Bed bug signs on a mattress seam

40 Signs of Bed Bugs Bites 40

41 What bed bugs eat and drink Blood 41

42 Where do bed bugs live? In the building In any crack or crevice where a credit card edge could fit In anything near where people rest Beds, sofas, bedside tables, recliners, picture frames… 42

43 How do bed bugs spread? Through walls along wires and pipes On anything coming from an infested unit: Furniture Backpacks Laundry 43

44 Inspection is key A thorough inspection is important to determine how widespread the infestation is. Inspection for bed bugs starts in the place where people sleep and moves out from there to other parts of the room Mattress Box Spring Bed Frame/Head Board Other furniture/storage areas Bed bugs may turn up in unexpected places in moderate and large infestations (desks, nightstands, picture frames, etc…) 44

45 Bed bug control If residents find bed bugs they should: Report the problem Not throw the mattress outcover it Not spray Prevent carrying the bed bugs to other places Prepare the unit for control measures 45

46 Bed bug control - Residents Role Residents can: Bag and remove all bedding, clothing, and other soft washable items from the infested area in plastic bags. Wash and dry sheets, blankets, clothing, etc…on hot setting. Isolate the cleaned items until bed bugs are gone. Wash headboard and bed frame and other infested furniture with hot water and soap/vinegar. Use a mattress encasement. 46

47 Bed bug control - Mattress encasement Traps live bed bugs inside. Zip, seal, and check for rips. Leave it on for 1-1/2 years (dont let it rip). 47

48 Bed bug control Residents should never spray or use foggers or bombs Sprays cause the bugs to scatter- making them harder to control 48

49 Bed Bug Control - Pest Control Operators Role PCO may: Inspect units (infested and adjacent units) Take apart furniture Put infested items in sealed plastic bags or discard heavily infested items Use A Hepa vacuum-to remove bed bugs and debris Heat or steam- to kill bugs Return in three weeks for follow up inspections 49

50 Bed bug control - Maintenance Staffs Role Empty dumpsters weekly Damage furniture left out for the trash so it cant be reused Inspect the laundry room weekly Be very cautious when working in unitsnever set items on or under beds, recliners, or sofas Eliminate bed bug hiding spots Fix peeling wallpaper and paint Caulk or seal cracks and crevices around the room and on furniture Seal floors or the spaces between floor boards and tiles 50

51 Bed bug control - Managers Role Maintain building free of pest harborage (hiding) places Communicate with the Pest Control Operator and residents Notify and assist residents in preparing for the Pest Control Operator visit Ensure all units which are infested (as well as adjacent units) are inspected and IPM strategies are employed by the Pest Control Operator 51

52 Bed bug prevention Launder clothing/bedding frequently Inspect donated/used furniture and clothing carefully and wash thoroughly Resident education Stress to residents that bedbugs are Not a sign of poor hygiene Encourage residents to come forward immediately at first signs of infestation 52

53 Review Questions True or False bed bugs are found only in beds. How do bed bugs get into a multi-family building? True or False bed bugs can only crawl. Once a unit is infested with bed bugs what are three ways residents can assist in controlling them? True or False foggers or bug bombs are effective in controlling bed bugs. Name two ways a manager can help control bed bugs in a multi-family building. 53
