The pooter, also sometimes called an aspirator or bug sucker, is a seemingly simple device with a fascinating and surprisingly varied history and application. Primarily used by entomologists, biologists, and hobbyists, it serves as a safe and efficient tool for collecting small insects and other invertebrates without causing them harm or risking injury to the collector. This article delves into the workings of a pooter, its various designs, its historical significance, and the best practices for its use.
Understanding The Basic Pooter Design
The core principle behind a pooter is creating a gentle suction that draws the target organism into a container. A typical pooter consists of a small, transparent container (usually made of plastic or glass), two or more tubes, and a filter. One tube, the intake tube, is used to draw air and the specimen into the container. The second tube, the suction tube, is connected to a mouthpiece and used by the collector to create suction. Crucially, the suction tube contains a fine mesh or filter to prevent the collector from accidentally inhaling the insect.
The container serves as a temporary holding chamber for the collected specimens. The transparency of the container is essential, allowing the collector to observe the captured insects without needing to open the device frequently, reducing the risk of escape.
How Does A Pooter Actually Work?
The operation of a pooter is remarkably straightforward. The user places the intake tube near the insect they wish to collect. By gently sucking on the suction tube, a negative pressure is created inside the container. This pressure difference causes air to rush in through the intake tube, carrying the insect along with it into the container.
The filter on the suction tube is the key safety feature. It prevents the insect from being drawn into the user’s mouth. The size of the mesh or filter material must be carefully chosen to be fine enough to block insects but porous enough to allow airflow.
The skill in using a pooter lies in applying just the right amount of suction. Too little suction and the insect will not be drawn in. Too much, and the insect might be injured against the sides of the container. With practice, users develop a feel for the optimal suction level for different types of insects.
Types Of Pooters And Their Variations
While the basic principle remains the same, pooters come in a variety of designs, each with its own advantages and disadvantages. The choice of pooter depends on the specific application, the size and type of insects being collected, and the preferences of the user.
Simple Tube Pooters
These are the most basic type of pooter, consisting of a single tube that serves as both the intake and suction mechanism. They are typically made from glass or plastic and are suitable for collecting very small insects or for use in confined spaces.
Dual-Tube Pooters
As described earlier, these pooters have separate intake and suction tubes, offering more control and hygiene. They are the most common type of pooter used by entomologists and biologists.
Aspirators With Filters
The quality of the filter is important. Some pooters have replaceable filters, allowing users to choose filters with different mesh sizes depending on the size of the insects being collected. High-quality filters are essential for preventing contamination of the suction tube and ensuring the safety of the user.
Powered Pooters
For collecting large numbers of insects or for use in difficult environments, powered pooters are available. These devices use a small electric pump to create suction, eliminating the need for the user to suck on a tube. While more expensive, they can be much more efficient and less tiring for extended use.
Modifications And DIY Pooters
Many entomologists and hobbyists modify commercially available pooters or create their own from readily available materials. This allows them to customize the design to suit their specific needs. Common modifications include adding lights for collecting insects at night or using different types of containers to accommodate larger specimens.
The Historical Significance Of The Pooter
The pooter has a long and interesting history, dating back to the early days of entomology. Before the invention of the pooter, collecting small insects was a challenging and often hazardous task. Collectors often resorted to using their mouths to suck insects into vials, which was both unsanitary and potentially dangerous.
The invention of the pooter revolutionized insect collecting, providing a safe and efficient way to capture small specimens. It allowed entomologists to study insects in greater detail and contributed significantly to our understanding of insect biodiversity. The pooter remains an essential tool for entomologists and biologists around the world.
Ethical Considerations When Using A Pooter
While the pooter is designed to be a non-lethal collecting method, it is important to use it responsibly and ethically. Over-collecting can have a negative impact on insect populations, so it is important to collect only what is needed for research or study.
It is also important to handle insects with care and to minimize the amount of time they are held in the pooter. Insects should be released as soon as possible after they have been identified or studied.
When collecting insects in protected areas or on private land, it is essential to obtain the necessary permits and permissions. It is also important to be aware of any local regulations or guidelines regarding insect collecting.
Best Practices For Using A Pooter
To ensure the safe and effective use of a pooter, it is important to follow some basic best practices.
- Choose the right pooter for the job. Consider the size and type of insects you will be collecting and select a pooter that is appropriate for the task.
- Inspect the pooter before each use. Check the tubes and filter for any damage or blockages.
- Use gentle suction. Avoid sucking too hard, as this can injure the insects.
- Keep the intake tube clean. Remove any debris that may clog the tube.
- Release insects as soon as possible. Minimize the amount of time insects are held in the pooter.
- Clean the pooter after each use. This will help to prevent the spread of disease and prolong the life of the device.
Pooter Construction: Materials And Techniques
Pooters can be constructed from a variety of materials, but the most common are plastic, glass, and rubber. The choice of materials depends on the intended use of the pooter and the preferences of the user.
Plastic pooters are lightweight and durable, making them ideal for fieldwork. They are also relatively inexpensive and easy to clean.
Glass pooters are more fragile than plastic pooters, but they offer better visibility and are less likely to react with chemicals. They are often preferred for laboratory use.
Rubber tubing is used to connect the different parts of the pooter. The tubing should be flexible and durable and should not react with the specimens being collected.
Constructing a pooter is relatively simple. The basic steps include:
- Cutting the tubing to the desired length.
- Attaching the tubing to the container and mouthpiece.
- Installing the filter.
Advanced Techniques In Pooter Usage
Beyond the basic operation, there are more advanced techniques that can be employed to maximize the effectiveness of a pooter and minimize harm to the collected specimens.
- Targeted Collection: Practicing precise movements with the intake tube to collect only the desired species and avoid accidentally collecting other insects or debris.
- Humidification: Adding a small piece of damp cotton or sponge to the container to maintain humidity and prevent desiccation of delicate insects, especially during longer collection periods.
- Cooling: In hot environments, using a cooler pack around the pooter container can help to keep the insects from overheating.
- Anesthesia (Controlled): In very specific research contexts, a carefully measured amount of anesthetic gas can be introduced into the pooter to temporarily immobilize the insects for easier handling and examination. This should only be done by trained professionals.
The Pooter’s Role In Modern Entomology
Despite advances in technology, the pooter remains a fundamental tool in modern entomology. It is particularly valuable for:
- Field Surveys: Collecting insects for biodiversity assessments and monitoring population changes.

The pooter, though a seemingly simple tool, plays a crucial role in the world of entomology and biology. Its careful design, diverse applications, and historical significance make it an indispensable device for anyone interested in studying and collecting small creatures. As technology advances, the pooter will likely continue to evolve, but its fundamental purpose – the safe and efficient collection of insects – will remain the same.
What Exactly Is A Pooter, And What Are Its Basic Components?
A pooter, also known as an aspirator or bug sucker, is a simple handheld device used for collecting small insects or other invertebrates without harming them. It allows researchers, entomologists, and even hobbyists to collect specimens for study or observation without direct physical contact, minimizing the risk of damage to the delicate creatures.
The basic components of a pooter typically include a small, transparent container (usually made of plastic or glass) to hold the collected specimens. Two tubes extend from the container: one with a mesh or filter on the end that is used to suck up the insect, and the other for the user to inhale through. The filter prevents the user from accidentally inhaling the insect or other debris.
What Types Of Insects Are Best Collected Using A Pooter?
Pooters are particularly well-suited for collecting small, delicate insects that are easily damaged by other methods. This includes creatures like aphids, small flies, springtails, and other tiny invertebrates found on leaves, flowers, or in soil. Their small size and fragility make them ideal candidates for the gentle suction provided by a pooter.
The device’s effectiveness is limited by the size and weight of the insect. Larger, heavier insects or those that are particularly agile might be difficult or impossible to collect with a pooter. Attempting to collect insects that are too large could also potentially damage the device or the specimen itself.
How Do You Properly Use A Pooter To Collect Insects?
To use a pooter effectively, gently place the end of the collection tube (the one with the mesh) close to the insect you wish to collect. Then, inhale gently and steadily through the inhalation tube. The suction created will draw the insect into the container. Avoid inhaling too forcefully, as this could damage the insect or cause it to become trapped in the filter.
Once the insect is inside the container, quickly remove the collection tube to prevent it from escaping. Observe the insect through the transparent container. Remember to empty the container regularly to avoid overcrowding and potential harm to the collected specimens.
What Are The Advantages Of Using A Pooter Over Other Collection Methods?
One of the primary advantages of using a pooter is its ability to collect delicate insects without causing them significant harm. Unlike methods that involve direct handling or pinning, the pooter allows for a gentle collection process that preserves the insect’s physical integrity. This is especially important for research purposes where morphological details are crucial.
Furthermore, using a pooter minimizes the risk of contamination or damage to the surrounding environment. It’s a non-invasive method that allows collectors to target specific specimens without disturbing the habitat or accidentally collecting unwanted organisms. This makes it a valuable tool for ecological studies and conservation efforts.
Are There Any Safety Precautions To Consider When Using A Pooter?
The most important safety precaution when using a pooter is to ensure that the filter is properly in place and functioning correctly. This prevents you from accidentally inhaling insects, soil, or other debris, which could be unpleasant or even harmful. Regularly inspect the filter for damage or clogs and replace it as needed.
Additionally, avoid using a pooter on insects that are known to be poisonous or irritating. Some insects release defensive chemicals or have stinging hairs that could cause an allergic reaction if inhaled or come into contact with your skin. It’s always a good idea to research the insects in your area before attempting to collect them.
How Do You Maintain And Clean A Pooter To Ensure Its Longevity?
Regular cleaning and maintenance are essential for ensuring the longevity and proper functioning of your pooter. After each use, empty the container and remove any debris that may have accumulated. Use a soft brush or cloth to gently clean the inside of the container and the ends of the tubes.
Occasionally, you may need to disinfect the pooter, especially if you’ve collected insects from potentially contaminated environments. Use a mild disinfectant solution and rinse thoroughly with water. Allow all parts of the pooter to air dry completely before reassembling and storing it in a clean, dry place.
Can You Build Your Own Pooter, And What Materials Would You Need?
Yes, building your own pooter is a relatively simple and cost-effective process. You’ll need a small, clear container (a plastic vial or jar works well), two pieces of flexible tubing (aquarium tubing is a good option), some fine mesh or cloth for the filter, and a drill or other tool to create holes in the lid of the container.
To assemble the pooter, drill two holes in the lid of the container, sized to accommodate the tubing. Insert one tube through each hole, ensuring a tight fit. Attach the mesh or cloth to the end of one tube to create the filter, securing it with glue or tape. The tube with the filter will be the collection tube, and the other will be the inhalation tube.
