Question: What is a very fast moving lizard looking pest that is imposible
to catch and impossible to poison?
ANSWER I'm thinking it might be a gecko.
Small lizards, skinks, and geckoes are common pests in houses and buildings that are surrounded by vegetation or are close to areas of dense (sometimes shaded) plants. They are pests simply by their presence indoors; they do not live in or reproduce in houses. They come in from surrounding vegetation seeking food, which is primarily insects.
Usually they are following the insects that are attracted to outdoor lights. Of course, they don't bite people or animals and would eventually move out of the house, except for those that get 'lost' indoors. I am not aware that these animals present a threat to people or pets.
The best control strategy is to keep them out by keeping doors and windows closed or screened;. Reducing the vegetation around the house and limiting outdoor lights at night may also be helpful.
