What is a healthy home?
3
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
Health effects that are associated with
housing conditions
Respiratory infections
Asthma
Injuries and burns
Allergies
Poisonings
Neurodevelopmental and
behavioral problems
Cancer
Death
5
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
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
children’s ears.
7
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:
8
Cancer
Birth defects
Central nervous system damage
Respiratory damage and
Endocrine disruption.
Drawbacks of Conventional Approach
to Pest Control
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.
9
What is the alternative?
-Integrated Pest Management
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…
10
How is the pest getting into your
building?
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.
11
Find their path and block it!
Install screens on windows and
doors.
Install door sweeps.
Caulk cracks and crevices in walls,
floors, around baseboards and
windows.
Seal holes around pipes.
12
Reduce Pest Food and Water Sources
Pests can find food in:
Trash cans
Appliances
Unsealed food on
countertops
Dirty dishes
Pet bowls
13
Pests can get water from:
Leaky roofs
Leaky plumbing
(toilet/sink)
Air conditioners
Sink and tub drains
Standing water in pet
bowls/houseplants
14
Control Pests with Low-risk Measures
15
Take Home Message
Pest Control = Shared Responsibility
Effective pest control requires a partnership between the
building owner/property manager, the tenant,
maintenance staff and the pest control operator.
16
Review Questions
There are seven steps to a healthier home- name three of
17
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

sources in the home.
Cockroaches
-What they are
-What they eat
-Where they live
-Prevention and control
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
German Cockroach
Medium size (3/4''), bronze,
20
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
Signs of Cockroaches
Live cockroaches
Dead cockroaches
Frass
Egg Cases
21
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
What cockroaches eat
Crumbs
Grease
Trash
Cardboard glue
Just about anything
23
Where cockroaches find water
Sinks
Counters
Floors
Pet bowls
Leaky pipes
Refrigerator drips
AC units
Shower stalls
24
What’s the problems here?
-How would you fix it?
25
IPM for Cockroaches
Inspect:
26
Prevention and Control
What kind?
Sanitation
How many?
Exclusion
Where are they living?
Least toxic pesticides
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 travel—at corners and
near warmth, food, and water.
Traps help find cockroaches when and where people can’t.
27
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
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
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 area—sanitation first!
Won’t work if contaminated by strong- smelling cleaners or other chemicals,
pesticide sprays or foggers, or nicotine from cigarette smoke.
30
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 andVentilation Systems should be
turned off!
31
Prevention and Control
-Insecticidal Dusts
Incorrect use of insecticidal dust
32
Never Use Sprays and Foggers
33

Bed Bugs
-What they are
-What they eat
-Where they live
-Prevention and Control
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.
36
Adult bed bug feeding on human
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
Signs of Bed Bugs
Bites
Blood spots
Shed skins
Dead bed bugs
Live bed bugs
Bed bugs and fecal spots.

Signs of Bed Bugs
Shed skins
39
Bed bug signs on a mattress seam
Signs of Bed Bugs
Bites
40
What bed bugs eat and drink
Blood
41
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
How do bed bugs spread?
Through walls along wires and
pipes
On anything coming from an
infested unit:
Furniture
Backpacks
Laundry
43
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
Bed bug control
If residents find bed bugs they should:
Report the problem
Not throw the mattress out—cover it
Not spray
Prevent carrying the bed bugs to other places
Prepare the unit for control measures
45
Bed bug control
-Resident’s Role
Residents can:
Bag and remove all bedding, clothing, and other soft washable items from the
46
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.
Bed bug control
-Mattress encasement
Traps live bed bugs inside.
Zip, seal, and check for rips.
Leave it on for 1-1/2 years (don’t let it rip).
47
Bed bug control
Residents should never
spray or use foggers or
bombs
Sprays cause the bugs to
scatter- making them harder
to control
48
Bed Bug Control
-Pest Control Operator’s 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
Bed bug control
-Maintenance Staff’s Role
Empty dumpsters weekly
Damage furniture left out for the
trash so it can’t be reused
Inspect the laundry room weekly
Be very cautious when working in
units—never 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
Bed bug control
-Manager’s 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
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
