Slug baits:

The ones containing metaldehyde are toxic to pets. They are cheap, abundant, and well advertised, but they seriously affect your pet’s central nervous system.
They can cause tremors, drooling, restlessness and often proceed to seizures and death if not treated.

Non-toxic alternatives:

• Beer or yeast placed in slug traps
• Copper bars or crushed eggshells placed around plants
• Iron phosphate pellets found under commercial name such as “Worry-Free,” "Sluggo," and "Escargot.”

Rodent Baits:

The most popular chemicals used to control rodent populations have been “anticoagulants.” These cause the body to lose its ability to clot normally, and in three to five days, a rodent will die of internal bleeding. Currently, one of the most popular baits on the market is bromethalin. Animals who ingest a substantial quantity of this bait can have tremors, running fits, seizures, and death within the first few hours. Smaller amounts may cause weakness and wobbliness that progress to paralysis and coma. Bromethalin is often green and in a block or pellets like many anticoagulants.

If you can’t use non-toxic alternatives, always use a tamper-proof bait station. For the best possible results, consult with or utilize a professional who is knowledgeable about proper baiting techniques, equipment, and current products on the market and who is accustomed to treating homes with pets and children.
