Insect trapping is a way of detecting the presence of insects in your storage or display areas. It is not, however, an effective means of controlling an infestation, as it will only assist in providing an indication of the types of pests present within your collection. This information can then be used to determine appropriate control and elimination methods.
There are two main types of insect traps available from specialist suppliers.
- ‘Blunder traps’. These are small pieces of cardboard with a strong adhesive surface onto which insects walk, or blunder, and consequently become trapped.
- ‘Pheromone traps’. These incorporate a synthetic pheromone product on a sticky base. Insects are attracted by the scent of the pheromone and are trapped on the sticky sheet. Pheromone traps are species specific, meaning that you need to know which type of insect you are trapping for so that you can select the trap accordingly. For this reason, the blunder traps tend to be more commonly used.
When using insect traps, it is important to remember that their success is determined by how effectively you use the trap. The trap needs to be placed in areas where pests are likely to hide or enter the exhibition and storage spaces, such as in dark places, window sills, corners and under furniture. They also need to be inspected on a regular basis to get an indication of the presence of a specific insect within the monitored area and to enable a prompt response.
Since much insect activity occurs at night, the traps are a useful aid in your monitoring program. It is important to remember, however, that they are a monitoring tool only and are not designed for, nor are they, an effective treatment measure.
Use Of Low Temperature – Fumigation By Freezing
Exposure to low temperatures has been found to be lethal to insects. It provides an efficient and inexpensive alternative to other fumigation methods.
Any material which may become brittle and crack when frozen should not be treated.
Low Oxygen Atmospheres
Another method of disinfesting material is by exposure to an atmosphere deficient of oxygen, for varying lengths of time. These ’low oxygen atmospheres’ can be achieved by using an oxygen scavenger, or setting up a system to expose the item to an inert gas such as nitrogen.
AGELESSTM is one such scavenger which is used extensively in the food industry to remove any oxygen present within a sealed bag or container, thereby preserving the product and preventing deterioration by mould and insect attack.
