Bed bugs are small insects that feed on human blood. They hide during the day and come out at night to feed. Their bites can cause itching and irritation. Bed bugs are commonly spread from one location to another through used furniture and luggage. Detecting and treating an infestation requires identifying the source, thoroughly cleaning the area, and applying residual insecticides to hiding places. High-risk areas for bed bug infestations include hotels, apartments, homeless shelters, and college dorms.

HEAD Lice (Lice)
What is Lice?
The head louse is an obligate ectoparasite of humans that causes head lice infestation. Head lice are wingless insects spending their entire life on the human scalp and feeding exclusively on human blood.
Scientific name: Pediculus humanus capitis
Length: 0.25 – 0.3 cm (Adult)
Structure and Food
Head lice have no wings, so they cannot fly. They have six legs with claws at the ends—that is how they attach themselves to hair.
Lice feed on blood—they use their mouth parts to bite into the skin and secrete a substance that acts to block clotting. They feed about four to five times every day.
Where Do They Come From?
Head lice infestations can happen to anyone, but they are a particular concern for school-age children. It is important to emphasize that poor hygiene, skipped baths or showers, or any other hygiene issue is not the cause of head lice. Children who live in crowded conditions may have more of a problem with head lice, but that is only because they are living close to one another and may sleep in the same bed. The only way head lice spread from one person to another is by direct head-to-head contact (as when kids hug or put their heads together to look at the same book) or by the sharing of hats, caps, hair ties, scarves, or any personal item such as combs or brushes.
Where They live?
Head lice can be found anywhere on the scalp, but are commonly found on hairs at the back of the neck and around the ears.
What Are the Symptoms of Head Lice?
Symptoms of head lice include:
extreme scalp itchiness
feeling like something is crawling on your scalp
sores and scabs on your scalp from scratching
Who Is at Risk for Head Lice?
Preschool and elementary school students have the highest risk of getting head lice. They tend to play closely together and share items that touch their heads. There is also an increased risk of head lice for family members of school-aged children. People who work in a day care center, preschool, or elementary school share this risk.
Thankyou! :)
Contracting head lice may be a rite of passage for many young students, as relatively few kids finish their elementary years without being affected due to the nature of lice and how they spread. Lice have basically been living on and around humans since the beginning of time. They are so ingrained in human history that the everyday expressions such as “lousy”, “nit-picking”, and “going over something with a fine-toothed comb” all stem from lice infestations!
Contrary to popular belief, contracting head lice does not indicate that a person is in any way unhygienic or unclean.

Difference between head lice, body lice and pubic licePrimoz Borovnik
As the human population grows, so too the infestations of parasitic bugs that thrive on the human body. In fact, contrary to what some believe, head lice, body louse and pubic crab infestations are not exchanged by other mammals but are species specific to humans, and humans only.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

5. Bed bugs are “true bugs” in the order
Hemiptera e.g. aphids, scales, cicadas.
Hemiptera is from the Greek hemi ("half")
and pteron ("wing"), referring to the
forewings of many hemipterans which are
hardened near the base, but membranous
at the ends.
Hemipteran mouthparts have evolved into a
proboscis, sheathed within a modified
labium to form a "beak" or “rostrum” which
is capable of piercing tissues and sucking
out liquids. Most hemipterans feed on
plants, but some feed on animals.
6. One theory is that bed bugs originated from bugs
that fed on bats living in caves. When man
moved into the caves the bugs adapted to feed
on them; when man left, the bugs went with
them.
Mentioned from earliest recorded history.
Commonly referred to as chinches by grand
folks. Mahogany flats and red coats were also
used.
Sometimes legs of bed were placed into cans of
oil or kerosene to prevent bugs from climbing
into the bed.
An assortment of treatments used for control.
7. Iron or brass bedsteads are better for controlling bed bugs than wood.
Kerosene oil, gasoline, or benzene will kill bedbugs if forced into
cracks and crevices with a feather or with a hand syringe.
A mixture of corrosive sublimate one ounce, alcohol one pint and
spirits of turpentine one-fourth pint painted into the cracks of a
bedstead with a feather
Boiling water poured over the parts of a bedstead that have been
carried where they may be liberally treated.
Sulfur candles for fumigating are now made and are very convenient
Hydrocyanic acid gas – this is the killing agent par excellence for
bedbugs and household insects. Formed by chemical reaction
between potassium cyanide, water, and sulfuric acid and is a deadly
poison to human beings and other animals. However it can be
generated and used in the fumigation of houses, without the least
danger if care and precaution are used in the work.
Insects Injurious to the Household, G. Herrick, 1914
8. “Bedbugs hide in cracks and crevices
during the day and come out at night to
suck blood. Hence, DDT spray must be
directed toward their daytime hiding
places. Apply the DDT spray to the
bedsteads, paying particular attention to
cracks in the wood and joins. Spray the
springs and mattresses. Strip the mat-
tress and spray all sides and the edges,
especially any crevices in which
bedbugs might hide and behind any
loose paper where they might
congregate”.

10. Bed bugs began to be reported as problems
during mid 90’s mainly by travelers staying at
hotels/motels
Lately severe problems are being reported
from apartment complexes and rental home
property in GA.
Resurgence of bed bugs could be the result
of changes in availability and use of residual
insecticides and/or resistance to current
insecticides. Less baseboard applications
are being made.

12. Derivation 1: According to the Oxford English Dictionary tight
in this expression is the equivalent of the only surviving use
of the adverb tightly meaning 'soundly, properly, well,
effectively'.” Most likely derivation.
Derivation 2: Before box springs were in use, old bed frames
used rope pulled tightly between the frame rails to support a
mattress. If the rope became loose, the mattress would sag
making for uncomfortable sleeping. Tightening the ropes
would help one get a good night sleep.
Derivation 3: In the early half of the 19th century it was a
common practice to wrap oneself completely in a blanket in
an effort to deter the aggravation of bed pests until one fell
asleep. Children were wrapped tightly, or bundled. Bundling
was a common practice in these times also for controlling the
activity of infants and toddlers whilst the mother
accomplished her daily tasks.
13. Bed bug - Cimex lectularius
Bat bug - Cimex adjunctus
Poultry bug - Haematosiphon inodorus
Swallow Bug - Oeciacus vicarius
Chimney Swift Bug - Cimexopsis nyctalis
These are insects in the order Hemiptera
making
them “true bugs”. Specimens must be
identified
in order to determine the appropriate
treatment.
15. Incomplete metamorphosis - bugs hatching from egg look just like very small
adults. There are three stages of development:
Eggs. Females lay one to five eggs a day over a period of two to 10 months,
producing about 200 total. They deposit the 1mm white eggs intermittently each day
in protected places near their hosts' sleeping quarters, cemented to bedding or in
cracks. The eggs hatch in one or two weeks, depending on temperature. Male
genital pierces the female during mating
Nymphs. Tiny and colorless at first, nymphs resemble small adults. They require a
blood meal between each of five molts. Blood meals take about three to 10
minutes, at which time the nymphs inject saliva containing an anticoagulant. The
nymphal stage can last for several weeks under favorable conditions or as long as a
year when temperatures or host availability are low.
Adults. About 1/4 inch long, 3/16 inch wide and reddish-brown in color. The
flattened oval bodies are adapted for hiding in narrow spaces. The head has a pair
of four-segmented antennae and piercing-sucking mouthparts that fold to lie
between the first pair of legs. The tiny wings are represented only by pads. The body
may become greatly enlarged and blood-red in color during a blood meal but turns a
dirty brown subsequently. Females can live nearly a year without food. Males and
females both feed on blood
16. Individual bites may cause
itching/irritation
Secondary infection of bites possible
Systemic effects from numerous bites
Loss of sleep
Emotional distress
Pathogens have been isolated, but bed
bugs are not know to transmit diseases
17. Bites typically occur at night while person
is in bed. Bites by bug may be painless,
person often wakes to find bugs in bed.
Bites are on exposed areas of skin.
Sometimes occur in linear groups of 3,
called “breakfast, lunch, and dinner”.
Individuals may react differently to bites in
terms of itching and discomfort.
Numerous bites may cause systemic
reaction
Topical treatment with hydrocortisone, oral
antihistamines or corticosteroids for
numerous bites. Antibiotic cream for
secondary infections.

20. Moved by travelers from hotel to hotel. Bugs
do not actually live on people, but may be
transported in suitcases or clothing in which
they hide.
Used or rented furniture may harbor
infestations
Infestations may be spread from residence to
residence during moves.
Infestations may spread from unit to unit in
apartments and hotels
21. Infestations are usually centered around bed
Typically the “victim” will find bugs in bed.
Bed bugs can be found hiding in crevices along the
mattress and box springs such as ticking, tags,
buttons, and rips. The gap between mattress and
box spring is a very good inspection site. Check
crevices and openings along the bed frame.
Dark spots on mattress and other surfaces results
from blood that has been digested and defecated.
As infestation grows, bugs may be found hiding
further from the bed - behind pictures, baseboards
nightstands, under carpet or wallpaper. Adjoining
rooms may become infested.

24. Identify bugs to determine if they are bed, bat or bird.
Eliminate bird or bat sources of bugs.
Clean room and remove clutter to eliminate bed bug
harborage.
Vacuum to remove bugs and eggs
Launder clothing and bedding in hot cycle to kill bugs
and eggs
Steam clean carpet and furniture to kill bugs and eggs.
Heat treatment of mattresses may be available.
Two-sided tape or band of petroleum jelly on bed legs
discourages bugs from climbing.
Mattress cover makes it more difficult for bugs to hide.
Easier to clean.
Treat bed frame and head board as permitted by
insecticide label. PCO might not want to treat mattress
or might use pyrethroids.
Treat cracks and crevices with a residual insecticide
Heat entire room to over 200o
