In an effort to find
a non-chemical means of coqui frog control, different kinds
of traps were tested for effectiveness. PVC pipes in a Tee-formation
appeared to be more attractive to coqui frogs since more eggs
were laid in the PVC pipes than in the bamboo traps (see details
under "Methods of Control").
No nesting was observed in straight PVC pipes (without Tee
at one end).
This method of trapping using bamboo
or PVC material appears ineffective because only 28% of the
bamboo traps and 28-30% of those made with PVC were occupied
after being set out for 4 months, indicating that the frogs
preferred more cryptic nesting places and that there was no
shortage of such places in the test plots. Trapping
may not reduce coqui frog populations significantly; however,
with this method, the frogs make themselves and their eggs
more accessible for removal, and the traps can be conveniently
checked during daylight hours.
