Secret Behind Doing Cockroach Trapping (Hotspot!)

Cockroach Trap is a must for a pest controller if he/she has the initiative to help his/her customers to solve their cockroach infestation. Trapping has to be part of the method in your cockroach programme. Trapping is not just for the sake of trapping the cockroaches. You should identify the caste of the cockroaches. Reason of this exercise will be able to tell you the hot spot location and you can have a better focus on your treatment. 

Identify: -

a) Male and Female cockroach

The easiest way to train up your technicians in identifying the caste will be, by looking at the size of the lower part body. You can identify with your naked eyes. Male cockroach has a sharper and thinner shape towards the end while female cockroach is rounder.

2) Gravid cockroach

If you see any German cockroach (Blattella germanica) as shown in Photo 4, this is called gravid cockroach. The gravid cockroach will carry its egg (ootheca) with her till the moment its about to hatch. Once the egg being deposited, it will hatch within 24 hours. Don't be surprise you will be able to see 34 to 36 nymphs crawling out from the egg case. 

3) Nymphs

To cut things short, for nymphs identification, I will put my focus on the first instar nymphs. It is very easy to be identified. The sizes of this category is very small. 


Secret Of The Caste Identification

1) Don't do cockroach count without identifying the caste. It sounds meaningless and will be a waste of everyone's effort.

2) Don't do cockroach count by just putting the number. It does not really serve the purpose.

3) Put yourself in a helicopter view after the cockroach count, check out where are the locations which you can find the most female cockroach, gravid cockroach and first instar nymphs. You will be able to see the pattern of your cockroach infestation. Those identified areas will be your hot spot of treatment.

4) I will not really put my attention at areas with a lot of male cockroaches because male cockroaches are not my target and they run far; whereas female and gravid cockroaches do not run far. Therefore, it's pretty straight forward for you to know the hot spot if you do your cockroach count on the right method.

5) Do not expect to carry out this exercise for once. Give yourself a timeline by continuous doing it for a certain period and you will be able to judge if, it helps you in bringing down the level of infestation.
