Special effects were heavily used for the film, such as the electronically controlled ants and bees. For the most part, the production team tried to use practical effects that would work in camera. For the scene where Wayne lands in the Thompsons' pool, Moranis jumped off a flying board in the form of a teeter-totter on a swing set. A stuntman pushed the board, sending him flying through the air and landing on a mat. Numerous storyboards were used for the film, particularly in the sprinkler and bee scenes. Scale models were also used for the bee scene, with miniature Russ Jr. and Nick plastic figures attached. Forced perspective was used in the giant cookie scene, to make it seem bigger. The child actors were strapped in for the scene with the broom. The bristles were actually pieces of foam that were carved and tied to a rig system.
