I live in a Hong Kong village house and here it's common to have Chinese geckos living in the house. They've been pretty unobtrusive so far and they do eat mosquitoes so I definitely wouldn't want to harm them.

Recently we've spotted cockroaches on a few occasions and were considering getting some poison traps like the ones linked here. Does anyone know if we're likely to poison the geckos as well if we install those? I guess the bait is unlikely to be directly attractive to geckos but will the poison spread through the food chain?

    What do geckos eat? My only contact with the species is auto insurance. Jan 31, 2020 at 3:47
  • Love that . don’t they eat mealworms? Or was that chameleons? + for the funny. I guess it could get in the food chain but I would expect larger animals to be affected like birds that eat bugs.

  • They eat pretty much all insects, including cockroaches. I guess if small birds aren't affected, neither would be geckos. Jan 31, 2020 at 5:26

    I'm voting to close this question as off-topic because it's about animal tolerance of poisons. Jan 31, 2020 at 17:13

When I was in Japan in the 1970's we were told that the geckos will eat the roaches. Fewer geckos means more roaches. I would assume any dead roaches would contain the poison. Any geckos eating roaches that had consumed the poison would be contaminated.
