Odontotermes Sp2

Odontotermes is a common genus of fungus growing termites. There are several species in this genus (52 known species according to some documentations), the largest of which (Odontotermes longignathus) is one of the most common. The soldiers of Odontotermes are monomorphic but not the workers. There are at least twenty species of Odontotermes in this location of which nine species have been documented.

The soldiers of this second Odontotermes termite species is 6mm.

With the mandible opened the characteristic tooth on the left mandible of Odontotermes is here clearly visible.

Camponotus Sp (Colobopsis group)

This species of Camponotus is arboreal, living inside tree trunks and branches. This small “truncatus group” species of the Colobopsis subgenus is dimorphic with two worker caste. In this species both the major and minor workers exhibit the truncation appearance that is definitive of this Camponotus Colobopsis subgenus. 

Most species of Colbopsis subgenus of the Camponotini tribe are true carpenter ants boring into trunks and branches of trees to make their nests.

Tapinoma Melanocephalum The Pesky Ghost Ant

Tapinoma melanocephalum is a small odorous ant that is more commonly found indoor than outdoor. The indoor species are usually lighter in color from those found outdoor especially in forest, wooded and agricultural areas. The outdoor species typically have longer legs and antennae.

This fast running tiny small pest ant have a similar habitat preference as the other common pest ant Monomorium pharaonis.

And like Monomorium pharaonis. they can live in relatively dry places, their workers traveled long distances to sources of water to collect the water back for their nest. They find their way into water containers to drink and some drowned fouling the water.

Their tiny size allows them to gain access to food in tight containers making them adept at thriving in human habitations.

This is not as common as the species above but both are about the same size.  

Tapinoma sp.

Tapinoma Sp2: An Outdoor Species.
 This outdoor Tapinoma species although the same size, has legs and antennae that are much longer.

 Close-up of this Tapinoma species shows the clearly evident longer legs and antennae. The longer limbs makes them appear to be slimmer. Because these ants are very small unless you examine them close-up you would not be able to see that this species found in the wild is different from the "domesticated" species of Tapinoma Melanocephalum.

Tapinoma Sp3: Another Outdoor Species.
Another species  of Tapinoma not found inside housing and buildings.
And here is the reason - the gyne of this Tapinoma species are as large as those of the black crazy ants Paratrechina longicornis.

Tapinoma sessile the odorous house ant is another species of this genus. This species has a particular much stronger smell and thus its common name.

Control And Eradications.

Solution based poison baiting is the fastest eradication methods for household pest ants such as Pharaoh ants and Ghost ants. Some documentations listed boric acid added to water or sugar water as an effective poison bait against Tapinoma melanocephalum. The same can be applied for Monomorium pharoanis.

Chemical sprays are the lest effective (unless the various nest locations are tracked down and repeatedly sprayed over a period of one to two months), followed by fumigation.

These pest ants which includes the black crazy ants because of their polygynous nest composition tend to have dispersed nests spread out over the residence and even across several residences in the case of apartment and high rise dwellers.

Of course keeping the residence clean and keeping stored food in well sealed containers will go a long way to minimise infestations as well as re-infestations.
