Keeping Lizards Off the Deck and Out of the House

Small lizards on a back deck in a warm climate—likely Mediterranean geckos or anoles. They eat insects and are beneficial.

Exclusion (Best Method)

• Seal all gaps ≥1/4": doors, windows, pipes, vents, utility entries.
• Use door sweeps, silicone caulk, steel wool, copper mesh.
• Pet door: install a tight-fitting flap or electronic collar-activated door.

Habitat Reduction

• Store firewood, boxes, pots off the ground.
• Reduce outdoor lighting (attracts insects = attracts lizards).
• Trim vegetation away from walls.

Repellents (Limited, Temporary)

• "Laxman Rekha" chalk line (Indian product).
• Garlic/cayenne/soap spray.
• Tabasco/water spray.

Reapply after rain. May deter dog from pet door if applied there.

Perspective

Lizards control spiders, roaches, mosquitoes. Tolerance is easier than exclusion. If they enter, gently catch and release outside.
