Cockroach Eggs Size – A Visual Guide

Cockroach eggs can vary in size depending on the species of cockroach. Generally, cockroach eggs are small and range in size from 1 to 8mm in length, with the most common size being around 3 to 4mm. The shape of the eggs also varies depending on the cockroach species. Some eggs are oval-shaped, while others are more elongated. Female cockroaches lay their eggs in a protective case called an ootheca. The ootheca can contain anywhere from 10 to 50 eggs. These eggs will hatch into tiny roaches and cause roach infestation. Therefore it is necessary to remove these eggs from house.

How to Get Rid of Cockroach Eggs?

Getting rid of cockroach eggs can be a challenging task, but it is possible by following the given steps.

Identify and locate the cockroach eggs

Inspect areas where cockroaches are commonly found, such as kitchen cabinets, under sinks, and behind appliances.

Clean and sanitize the area

Use hot soapy water to clean and sanitize the area where the eggs are located. Clean all cracks and crevices because the cockroaches hide their eggs in these areas.

Use insecticides

Apply insecticides specifically designed for cockroaches to eliminate any remaining eggs. Follow the product label instructions carefully and wear protective gear, such as gloves and a mask.

Seal entry points

Prevent future infestations by sealing any cracks, gaps, or holes in walls, doors, and windows that can serve as entry points for cockroaches.

Regular cleaning and maintenance

Implement regular cleaning and maintenance practices to reduce food and water sources for cockroaches. This will help prevent new infestations and reduce the likelihood of cockroach eggs being laid in the first place.
