When I was having joint inspection with my customer the other day, I spotted Stegobium paniceum at their gluten powder. Stegobium paniceum is well known as drugstore beetle of biscuit beetle to most of the people.

Stegobium paniceum is small in size. The size of an adult can be up to 3.5mm. You will start seeing the infestation if your products have been kept for some time after the last fumigation. My customer told me, they just received the goods from their supplier in the afternoon and I taught her to question back her supplier, 'When was the gluten powder last fumigated?'
She threw me a question, 'How often do they need to fumigate the products?' Well, as a professional person in this industry, we shall explain to the customer, 'It's depends on what type of your targeted pest. Identify your pest. Understand their life cycle. How long does it take from egg to become an adult? From there, you will know when is the next cycle of reinfestation.' You will get your answer.
Secondly, it is depends on the customer's objective. Do you want to take precaution steps or treat whenever it is necessary? She told me it will be very costly if she is on the precaution steps.
Service provider can only consult customer what is the necessary step in controlling their pest. We can recommend what is the frequency of treatment to tackle their infestation. However, decision is always in the customer's hand.
Infestation is just like coughing. As a doctor we give prescription to take the cough mixture 3 times a day, but because of cost saving, the patient consume once a day. To have a better cost efficiency, some will only take the cough mixture whenever they hear the coughing sound. Reflect back to the infestation. Most of the customers will only proceed with fumigation treatment whenever they see the severe infestation happens. No precaution steps on infestation is taken on their products.
