Ever seen alot of lizards in your home?
Tried to take a boom or newspaper to whack them but they escaped
in the wall or some other hidden places before you could even go
near them?
Try using those sticky and messy lizard trap but seems that none
of the lizards fall into the trap?
Why not use Vacume cleaner to get rid of them 
When you see the lizard on the wall, simply on the vacum cleaner
and run towards it and suck him into the vacum cleaner and than
kill him after that
