Bacillus thuringiensis or BT is a type of bacteria that's used to control the population of caterpillars. This natural pest control has been used by farmers and gardeners since the 1930s. Commercial preparations of the bacteria are still widely available today in feed stores and garden shops around the country. An alternative would be deltamethrin or permethrin dust.
Some people do and some people don't. But for animals some people protest on killing all of the dangerous animal like the kind that are venomous but otherwise no. And for plants some people would like to get rid of cactuses and those other dangerous plants!
Repot your plants every six months and use yellow sticky pads. They are hard to get rid of though. Try sprying the soil area with Neem Oil, it will smother them.
