Counting errors (fan failure)
Symptoms:
• Mosquito counts may appear low
• Small counts may appear high
• Catch bag (if used) may be empty
• When viewing “List” data, Power Draw is near 0, even
when fan is supposed to be on
Cause:
Fan has failed.
Solution:
Check fan wiring; if necessary replace fan.
Counting errors (overcounting)
Symptom:
Fewer mosquitos in catch bag than counts on
website.
1. Cause:
Mosquitos might be able to escape if the catch
bag is full or due to a reduced air flow. When leaving
the trap, the mosquitoes sometimes cross the infrared
barrier several times (32) and are therefore also counted
several times (33).
Solution:
A) Remove the funnel net and catch bag (34).
B) In case you need to analyze the mosquitoes, install a
catch bag below the fan (35).
2.
Cause:
Mosquitoes were “stolen” by other insects (e.g.
ants)
Solution:
Place the trap ant-protected, e.g. in a water bath or grea-
se the basement with petroleum jelly.
Counting errors (undercounting)
Symptom:
More mosquitos in catch bag than counts on
website.
Cause:
Some mosquitoes were misclassified as large.
Solution:
An 80% or higher accuracy is normal. If the
-
re are no other large objects in the catch bag, use the
sum of mosquito and large object counts (activate un-
der “Chart settings“/“
Insect types“
“Large objects“). Add
both together, accuracy may increase.
