What type of treatment is effective for controlling fleas in a household?

The effectiveness of using insect growth regulators combined with residual insecticides for controlling fleas in a household stems from their ability to disrupt the life cycle of the pests while also providing immediate effects. Insect growth regulators (IGRs) target the juvenile stages of fleas, preventing them from maturing into adults and reproducing. This helps to reduce the population over time. Residual insecticides work by killing adult fleas on contact and then continue to provide protection against future infestations. Using these two types of treatments in conjunction maximizes the chances of not only eliminating existing fleas but also preventing future generations from developing.

Cultural practices, while beneficial for overall pest management, may not provide immediate or effective control in the context of a significant flea infestation, and thermal treatment, although effective in some scenarios, may not be feasible for every household. Traps and baits are often used for other types of pests but are not generally effective for controlling fleas, as they do not address the broader issue of flea populations residing in carpets, bedding, and other surfaces. Thus, the combined approach of IGRs with residual insecticides is the most comprehensive method for managing flea issues effectively.
