Aetrapps are used to capture eggs of Aedes mosquitoes.
Follow the step by step guideline to build yours and, if necessary, click on the images at any time to see them enlarged.
1.
Cut a transparent 2-liter
plastic bottle at exactly 13 cm of height.
ATTENTION
Do not use 1.5 liter-bottles and colored bottles
since they can affect the attractiveness of the trap.
2.
Both parts will be used.
3.
Cut the bottleneck as designed to build the dispenser of grass, which will attract mosquitoes.
Also, cut a strip of approximately 1.5 x 7 cm.
4.
The dispenser of grass and the strip
must look like this.
5.
Pick up a small portion of grass.
6.
Chop the grass into very small pieces.
7.
Cut a square of approximately 6 x 6 cm out of a coffee filter.
8.
The parts of the dispenser of grass are ready!
9.
Fill in the bottle cap with the chopped grass.
10.
Place the piece of coffee filter on the cap with grass.
ATTENTION!
Check if the cap and the neck are dry not to tear the paper.
11.
Thread the neck on the cap carefully not to tear the paper.
12.
Cut the excess paper from the edges.
13.
The dispenser of grass is ready! It will work as a tea bag in the water.
14.
To make the paper strip, you will need:
– Watercolor Paper
– One plastic card (54 x 86 mm)
– A coin of R$ 1.00
– Blue ballpoint pen
ATTENTION!
Look for a watercolor paper with a weight of 300g/m2 on your local stationery
It can be white or cream. Cardboard and other papers are not resistant to water.
15.
Use the card as mold and draw a blue rectangle on the paper.
ATTENTION!
The pen must be blue for the system to recognize the circle; drawings in ballpoint pens do not blur in the water.
16.
Place the coin in the center of the rectangle.
17.
Using the coin as a mold, draw a blue circle in the center of the rectangle.
ATTENTION!
Check if the circle is completely closed, without blank spaces.
18.
Cut the rectangle carefully, trying to keep the blue border in the palette.
19.
The palette is ready!
20.
The plastic strip previously cropped will be used to avoid the contact of the clips with the paper, so it will not be stained by rust.
21.
Attach the strip on the edge of the container; clips must not touch the paper.
22.
The dispenser of grass will be fixed with another clip.
23.
Attach the dispenser of grass on the opposite edge of the container.
The cap with grass should stay at the bottom.
24.
Coat the container with black electrical tape.
Disassemble the palette and the dispenser of grass for now.
25.
Starting at the bottom of the trap is easier.
26.
Glue strips from the center to the edges.
27.
Avoid leaving gaps.
28.
Keep coating the sides, in a circular movement.
29.
The container should be coated to the top.
30.
Drill two small holes on opposite sides, very close to the edge.
31.
Re-attach the palette and the dispenser of grass on opposite edges.
32.
Your trap is ready!
33.
Make sure that the cap with grass is at the bottom and that the clips are not touching the paper.
34.
Use the side holes to attach a piece of string.
35.
Fill the trap with clean water up to the top of the circle of the palette.
The water level can decrease during the week due to evaporation.
ATTENTION!
The reduction of the level and water by evaporation during the week is normal!
Do not put more water not to submerge the eggs!
36.
Using a nail, hang the trap on the wall in an outdoor area of the house which is well protected by a roof or eave.
Important note: The trap must be protected from excessive sunlight, avoiding very quick evaporation, and protected from rain and splashes of rain, avoiding dirt in the palette.
ATTENTION!
Look for a well-protected place in the yard, such as a porch or a wall with a large eave.
Do not place the trap underneath bulbs as they attract insects that will eventually fall into the trap. The darker the location of the trap, the better.
37.
The height of the mouth of the trap should be between 80 cm and 1 meter from the ground.
Tell the children who live in the house to not to touch the trap!
38.
Using the AeTrapp application, click “Armadilhas/Traps” in the bottom menu.
39.
Click the “+” symbol in the top right corner to register your trap.
40.
Take pictures of your trap in the place where it was installed, fill in all required data and click Confirm: your trap is registered in the system!
Now wait one week to photograph the first sample — you will be notified not to forget this step.
Eggs are often not found in the first two weeks – it is perfectly normal, do not be discouraged!
