Frogs are shy creatures and by nature nocturnal so the best time to catch them would be at night. Also, they love damp, wet and dark places e.g. bathrooms, under kitchen sink, etc. So IMO these would be the places you need to look first.

Catching frogs are not easy. You can't just put in bait somewhere e.g. a small pan and expect them to come in, eat then not jump out. You need to design a trap or something where they can get in but can't get out.

When I was young, I used to catch palakang bukid for food. For bait, I used worms skewered on the stem of the small talahib/grass which was then attached to a tansi/fishing line. Once the frogs clamp on the bait, they usually never let go. Unbeknowst to many, frogs are little greedy creatures when it comes to food: when it swallows/bites into something it likes, the likelihood of it letting go is small.

If you have a cat at home, let it loose: these furry friends of ours would "remove" the frogs from your home in no time.
