What can be used to remove flea eggs from carpets as a mechanical control method?

1. Fly swatters

2. Vacuum cleaners

3. Fans

4. Spray pesticides

The correct answer is: Vacuum cleaners

Using vacuum cleaners to remove flea eggs from carpets is an effective mechanical control method. Flea eggs are often laid in the environment, particularly in carpets and upholstery, where they can be difficult to eliminate through chemical treatments alone. A vacuum cleaner can effectively suction up these eggs, along with adult fleas and larvae, thereby helping to break the flea life cycle. Vacuuming not only removes visible flea eggs but also disturbs the environment enough to encourage other fleas to emerge, making it easier to manage the population. Regularly vacuuming areas where pets spend time is essential in a comprehensive flea control strategy, as it can reduce the number of eggs that may hatch into adult fleas later on. Additionally, emptying the vacuum cleaner's contents promptly after use is crucial to prevent any remaining eggs from re-infesting the area. Other methods, such as using fans, do not effectively remove flea eggs. They may aid in drying out damp areas but do not provide the mechanical action needed to physically remove the eggs. Similarly, while fly swatters could potentially kill adult fleas upon contact, they cannot assist in egg removal within the carpet. Spray pesticides are also not a mechanical method; rather, they are a chemical control method that may not address the eggs already laid
