dont kill the house lizard, they help you by eating those bugs, seriously
if there are many then that means you have lots of bugs.
reduce the bugs and they have not enough food they will move elsewhere.
the electric fly swatter are not for large bugs la. for cockroach use old newspaper.
roaches are very stong, they adept to the environment easily. they evolved with the environment. they don't die so easily. during the age of dinosaur, all spices die, but roach survived...
Cockroaches are among the hardiest insects on the planet. Some species are capable of remaining active for a month without food and are able to survive on limited resources like the glue from the back of postage stamps.Some can go without air for 45 minutes.
It is popularly suggested that cockroaches will "inherit the earth" if humanity destroys itself in a nuclear war. Cockroaches do indeed have a much higher radiation resistance than vertebrates, with the lethal dose perhaps 6 to 15 times that for humans.
The cockroach's ability to withstand radiation better than human beings can be explained through the cell cycle. Cells are most vulnerable to the effects of radiation when they are dividing. A cockroach's cells divide only once each time it molts, which is weekly at most in a juvenile roach. Since not all cockroaches would be molting at the same time, many would be unaffected by an acute burst of radiation, but lingering radioactive fallout would still be harmful
that was why i noticed baygon took quite a while to eliminate roach.
