What is Palmetto Bug?

A palmetto bug or a Florida woods cockroach is a mild-aggressive and large species of cockroach which is found on the palmetto trees (which gave them their present name) in the Northern parts of America.  

They belong to the order – Blattodea, family – Blattidae, genus – Periplaneta, and species – Periplaneta americana.

These pests are detritivores and feed on decomposing plant remains and plant materials. They feed on leaf litter, log remains, compost piles, and decaying organic materials.

They are large-winged, reddish-brown insects with a creamy prothorax. The prothorax has dark markings which resemble a sunglass.

Palmetto bugs are one of the largest cockroach species in North America.

Palmetto bugs infest homes during cooler weather.

Their infestation causes havoc among people and households due to the deadly viruses and bacteria they carry along with them, which could cause infectious diseases in adults and children.

 Behaviour wise the Palmetto bugs are not very aggressive, though they might bite sometimes (in case of threat or when not able to fly).

The bites of these unique and beautiful species are not very harmful to the human species, though they could cause skin irritations in some rare cases.

What is Cockroach?

A cockroach is a reddish, flattened, and oval-bodied pest that is found in moist and humid areas.

These areas include sewages, canals, garbage cans, moist areas of a household, and under-leaf litter.

They belong to the order – Blattodea, family – Blattidae, genus – Periplaneta, and several other species. There are a total of 4000 species of cockroaches.

A few of the species are listed below –

• American cockroach
• Smoky brown cockroach 
• Ectobius cockroach
• Parcoblatta virginica
• Cuban cockroach
• Speckled cockroach
• Tryonicidae

A cockroach’s body is a little complicated and structured quite differently. Their head is bent slightly towards the downward direction, and their mouthparts point backward.

This distinguishes a cockroach from other insects as the latter has its mouthparts pointing towards the forward or downward direction.

Different species of cockroaches have different characteristics and traits. Some have large wings to fly, while others are quite sharp teethed to bite into prey or a predator. 

A cockroach develops into an adult male/ female by undergoing three developmental stages. These three stages are –

• The egg stage – A cockroach lays 10 to 55 eggs simultaneously, growing in moist and shady areas.
• The nymph stage – After hatching from their respective eggs, the babies go into a nymph stage.
• The adult state is the final stage, where a cockroach is fully mature and reproductively active.
