1. Tomcat Stings
Prof DR Dr Ariyanto Harsono SpA(K) 1

2. Introduction
The term Tomcat sting is actually incorrect.
Tomcat does not sting or bite. Tomcat body
touches on the human body is enough to
make toxic effects. Tomcat includes strains of
beetle family of insects. Or more precisely
beetle also called Ants “Semai”.
2Prof DR Dr Ariyanto Harsono SpA(K)

3. This beetle has a size less than 1 cm. Yellow
body, dark in the head, and tail. Middle of the
abdomen is dark green has pair of hard wings.
Typically, the region appears crawling around,
hiding the wing and look more like ants.

4. 4Prof DR Dr Ariyanto Harsono SpA(K)

5. If disturbed, it will increase the portion of the
stomach looks like a scorpion beetle to scare
the enemy. There is fluid in Tomcat’s body that
12 times more powerful than cobra venom
though. Haemolymph fluids or toxins referred
to as "aederin".
5Prof DR Dr Ariyanto Harsono SpA(K)

6. How to cope Tomcat’s venom
Tomcat will automatically release toxic fluid when in
contact or collide with human skin. Tomcat will
also discharge the toxin on items such as
clothing, towels, or other objects. That's why, if
exposed bed linens, towels and equipment
poisoned tomcat should be allegedly washed. If it
has been exposed to Tomcat toxins, for first aid
immediately wash / rinse with clean water and
soap.
6Prof DR Dr Ariyanto Harsono SpA(K)

7. If it comes in contact with Tomcat:
1. Immediately wash the affected area with soap and water.
2. Severe skin reaction to get better medical care.
3. Make sure the insects are no longer in bed and close all the windows
when the evening.
4. Materials such as antiseptic solution of potassium permanganate
(KMnO4) can be used for washing.
5. Antiseptic mixed with a low strength steroid cream can reduce
injuries. If it appears as a speck of red spots, rub the ointment on
the skin immediately with Hydrocortisone 1% / betametasone with
neomycin sulfate 3 times a day.
6. Do not let the wounds were still wet in the sun, because it can cause
black scars is hard to be removed.
7Prof DR Dr Ariyanto Harsono SpA(K)

8. Tomcat always appear in the light
All insects have a role in disease transmission, including
Tomcat. This insect has toxins that can cause skin
reactions. These insects are found in gardens or fields
and usually only causes a reaction in the skin. In
contrast to other insects such as centipedes, toxins can
cause paralysis due to strike a nerve, if exposed to
insect venom is then immediately cleaned and given
anti-allergy medications such as hydrocortisone
ointment or betamethasone so the reaction is not
excessive. Body's reaction to Tomcat poison in
someone is different between each other, there is no
light weight.
8Prof DR Dr Ariyanto Harsono SpA(K)
Tomcat often arise when the day before the
night, at the time people turn on the lights.

9. Tomcat has a Latin name of Paederus
riparius, Named Tomcat as a cursory look at the
insect's impression pictured as the USA Tomcat
fighter. These insects live in humid areas and
generally will follow the light of the lamp, eating
animals such as fleas and beetles pests of rice.
Tomcat will remove toxins from the body or in
contact with human skin. This poison will cause
itching and also cause thermal injury to the skin.
9Prof DR Dr Ariyanto Harsono SpA(K)

10. Haemolymph fluid in the body (except the wings)
these animals have the potential harmful toxins.
The toxin is referred to as 'aederin': (C24 H43 O9
N) was identified in 1953.
10Prof DR Dr Ariyanto Harsono SpA(K)

11. Tomcat will automatically release the liquid in the
event of a collision with a touch of human skin.
Can be touched indirectly through
towels, clothing or other equipment
contaminated by tomcat poisonous. That's why, if
hit by automatic dermatitis such as sheets, towels
and equipment exposed to toxic tomcat should
allegedly be washed.
11Prof DR Dr Ariyanto Harsono SpA(K)

12. Tomcat is actually useful to repel pests, leafhoppers are prey
Tomcat. Tomcat not actually hostile to humans. So, maybe
there is human activity that interferes with Tomcat. In the
cities of Jakarta and Surabaya, Tomcat insects usually live in
areas that have trees or plants such as city parks. Tomcat fly
with the body "standing", not slumping. The wings do not
cover the entire body, unlike other insects. A Tomcat
affected skin area will usually experience itching. When
severe, the skin may blister. Not expected to face Tomcat
attacks panic as poison is not deadly. Skin that has been
"bitten" can be washed with soapy water for first aid
antiseptic.
12Prof DR Dr Ariyanto Harsono SpA(K)

13. Characteristics of the Tomcat affected skin is very
individual, can be mild to severe:
1. Appear reddish color of the skin
2. The skin will feel itchy
3. Irritation or inflammation of the skin
4. Will appear blistered skin due to irritation
5. If severe, then there will be pus in the skin

17. Prevention of Tomcat’s
envenomization
Pesticide for Tomcat is a vegetable extract that
typically contains galangal, lemongrass and neem
leaves in order to kill tomcat. Other things can be
done as a form of prevention is through people's
behavior for example by closing the doors and
windows before turning on the lights, because
tomcat follows the light.
Tomcat usually appear to crawl and hide the wings
and look more like ants. If disturbed it will improve
the look of the stomach like a scorpion.
17Prof DR Dr Ariyanto Harsono SpA(K)

18. 1. Avoid direct contact.
Direct contact with Tomcat is tantamount to attach the skin to toxins.
Usually skin will feel the heat followed by the appearance of itchy
spots, watery and black marks on the skin. If you want to get rid of
the animal, use paper or other batsman, not by hand.
3. Put mosquito nets and also close the windows and doors before
turning on the lights to prevent the entry of beetles.
5. Make sure the home environment clean
4. Annihilate the untreated plants and ensure cleanliness of the park so
that animals will not be nested. Prevention is better than cure so
make sure the house is clean and comfortable so do not be
distracted from Tomcat problem. Although insects are useful to
farmers, we also must remain vigilant.
