2. BED BUGS OVERVIEW
 External parasitic insect
 Mainly active at night
 Feed on the blood of warm blooded sources, mainly

3. THEY’RE BACK… BUT WHY?
1. Increased international travel
2. resistance
3. Change in general pest control
methods
4. Decreased public awareness
5. Reduced available products for
control
6. Lack of research and development
WALTER WASWA,BSC.MED.LAB

4. BED BUG BASICS
o Feed only on blood
o Feeding lasts 3 – 12 minutes
o Nocturnal
o Can detect and avoid chemicals
 Excellent hitchhikers
 Infestations are not always linked to unclean conditions
o Crawl up to 20 feet to feed
o A bed bug can live upto six months without feeding on its host.

5. LIFE CYCLE
WALTER WASWA,BSC.MED.LAB

6. MATING……………..AUCH!
 Males pierce the female's
abdomen with his hypodermic
genitalia and ejaculates into the
body cavity.
 Male bed bugs sometimes
attempt to mate with other
males and pierce their
abdomens.
 This behaviour occurs because
sexual attraction in bed bugs is
based primarily on size, and
males mount any freshly fed
partner regardless of sex.

12. NIME SHIBA!

13. IDENTIFICATION
Immature:
Almost completely transparent
when unfed
Light red after feeding
Mature adults: different shades of
brown fed and unfed
WALTER WASWA,BSC.MED.LAB

14. HABITS
 Attracted by warmth and
CO2
 Penetrate the skin with two
hollow injector tubes
 One tube for injecting saliva
 The other tube for
withdrawing blood
 After feeding for approx. 5 –
15 minutes, the bed bug
returns to a hiding place
WALTER WASWA,BSC.MED.LAB

15. BITE IDENTIFICATION
 Typically no red center
spot
 Bed bugs tend to focus
on exposed skin
 Rarely occur on palms
or soles
 Often occur in rows
and/or groups

16. BED BUG PREVENTION
1. Look for bugs, stains & check the seams
& puckers of the mattress.
2. If you buy used furniture or clothing, treat
it before it enters your home.
3. Clothing should be washed in hot water &
dried on the highest heat setting.
4. Furniture can be carefully inspected
before you bring it home.
5. Eliminate Clutter
6. Stop the spread!
7. Start with thorough cleaning
WALTER WASWA,BSC.MED.LAB

17. CONTROL AND ELIMINATION
 Your responsibilities after you find bed bugs:
 Start with a thorough cleaning
 Do not remove and/or discard furniture
 Wash all linens and clothing in hot water >120F
 Dry all linens and clothing on high heat
 Items not suitable for extensive cleaning can be
contained in plastic bags and placed outside in the
heat
 Repair all cracks and crevices in living areas
WALTER WASWA,BSC.MED.LAB

18. HEALTH RISK?
 Sleeplessness
 Agitation
 Anxiety
 Emotional Stress
 No conclusive evidence of disease transmission
 Possible Vectors?
 >20 pathogens have been found in bed bug guts
 According to the Mayo Clinic (mayoclinic.com), by feeding on infected people,
bedbugs can be infected with some bloodborne diseases.
 In addition, the trauma from bites can lead to secondary infections especially
when it happens in highly susceptible populations.
 Researchers in British Columbia, Canada recently found MRSA and VRE infected
bed bugs in homeless shelter

25. MKILIFI INSECTICIDE
 oil is easily extracted from the leaves and seeds
=organic pesticide
 Neem oil basically affects insects by intervening at
several stages of an insect’s life
 It works by interrupting the reproductive cycle of insects.
 Once ingested, it affects the hormonal system of the
insect, causing it to forget to eat and stop moulting,
mating and laying eggs.
 This eventually sees the complete destruction of the
insect population in the designated area as the older
insects die off without producing offspring.
 Neem oil is also powerfully aromatic and gives off an
odour that insects do not like, protecting plants by
making them unappealing.

26. LEAVES
 Use a five gallon bucket
 Fill 1/3 of the bucket with smashed/crushed neem
fruit and seed or well chopped leaves
 Fill the bucket with hot water up to the 2/3 mark
 Cut a bar of organic soap into thirds, add 1/3 of the
soap into the water and stir until it has dissolved
 Stir mixture repeatedly for one week twice a day
 Filter the solution
 Spray this on your bed fulcar,
 wall or any crevices
WALTER WASWA,BSC.MED.LAB

27. SEEDS OIL
 To make a litre of general-purpose neem oil spray,
mix 5mls neem oil, 2mls of liquid soap and 1 litre of
water.
 Add the soap to the water first and then slowly stir
in the neem oil.
 Pour the mixture into a spray bottle and it is ready
to use.
 You’ll need to use the mix within 8 hours as beyond
that the ingredients will start to break down.
 If you’re pregnant or trying to get pregnant, consult
your doctor before using neem oil as it can interfere
with your hormonal system
