As burrowing cockroaches, these insects may enter homes in the soil of potted plants. Surinam cockroaches thrive in warm, humid places, so they may also get indoors via items brought in from greenhouses. In some areas, these pests crawl inside through open doors and windows and other cracks and gaps that allow them to get inside.

How Serious are Surinam Cockroaches?

Surinam cockroaches don’t live long in homes where moisture and humidity is low. Their impact on buildings is minimal and bites are unlikely. Their species causes widespread damage to regions prone to high heat and humidity including:

  • Gardens
  • Greenhouses
  • Lawns

Signs of Infestation

Damaged plants and sightings of the pest indoors are the primary signs of an infestation. Sticky traps can help to monitor activity, and homeowners should remove affected indoor plants.

Behavior, Diet, & Habits

What Do They Eat?
These pests burrow into the ground and feed on plant stems and roots.

Where Do They Live?
Surinam cockroaches are nocturnal and live underground, so residents may not see them. These cockroaches need warmth and moisture and cannot survive cold winters.

Geographical Range
These garden pests are most commonly found in humid, tropic areas such as the southeastern United States.

Only females are important in reproduction since these cockroaches reproduce asexually, so male fertilization is not necessary. But another interesting and unusual characteristic of Surinam cockroaches is they are oviparous.

This means a female will carry her egg case inside her body until her nymphs hatch from the eggs and are birthed by the female. They can have an average of 3 egg cases which contain an average of 24 eggs. Cockroach reproduction occurs year-round.
