Clearout German Cockroach Infestations

An IGR product is a powerful tool that is worth incorporating into German cockroach control programs to achieve long-lasting results.

When it comes to combating German cockroach infestations, having the right tools at your disposal is crucial. Using the powerful combination of an insecticide and an insect growth regulator (IGR) can help pest managers win the war against these persistent pests. Sherwood Chemicals offers two products in its Clearout range – an aerosol and a dust – that both contain an IGR, which when used together, ensure a cockroach-free environment.

To effectively combat German cockroaches, proper identification is key. Look for their distinctive light brown colour and parallel stripes. Thoroughly inspect the site, focusing on high activity areas such as kitchens, bathrooms and areas with moisture. This initial assessment will help to gauge the extent of the infestation and pinpoint critical target zones as part of your treatment plan.

Pest managers can first apply Clearout Plus IGR Aerosol to identify cockroach harbourages and target pests in infested areas such as cracks, cervices, baseboards, under sinks, and behind appliances. The compressed LPG and solvents in Clearout Aerosol have a flushing effect and the combination of fipronil and pyriproxyfen provides a long-lasting residual kill that combats resistance by incorporating two different modes of action and disrupting the insect breeding cycle. As always, prioritise safety, applying the aerosol in areas that are away from food, electrical motors and open flames.

Secondly, for difficult areas, pest managers can use Clearout Plus IGR Dust, which combines double strength permethrin with pyriproxyfen. Using the easy to use E-Duster applicator, the dust should be applied to cockroach hideouts where the use of an aerosol is unsuitable, such as electrical motors, ovens or areas that contain an open flame. The specialised dust is lightweight and flows deep into voids to cling to surfaces, allowing the dust to be more actively available than a liquid application. It provides lasting control by inhibiting cockroach development and population growth by stopping the breeding cycle.

Lastly, creating a less attractive environment for cockroaches to thrive is crucial in a successful treatment plan. It also sets the expectations with regards to good sanitation practices with the business or homeowner prior to the treatment. Good sanitation means the removal of all cardboard boxes from incoming goods and storage areas as well as the treatment of drains with a probiotic product. CleanOut Probiotic Drain Foam targets the organic material that acts as a food source for cockroaches. Cracks and crevices that serve as entry points should also be sealed, paying close attention to gaps around pipes, vents, and windows. By denying access, eliminating harbourages and removing food sources, the stage is set for an effective treatment.

With Clearout Plus IGR Aerosol and Clearout Plus IGR Dust as your trusted allies, victory over German cockroach infestations is within reach. Hitting cockroaches with two dual-active products means they have nowhere to hide.
