Dog Safe Slug Killers – Get Rid Of Slugs Without Harming Your Pet

A slug infestation can cause considerable damages in your garden. Before you purchase some slug or snail baits, you should know that some products are poisonous to dogs. This doesn’t mean you shouldn’t take action to get rid of slugs and snails since this pest can transmit lungworms to your pet. Here is how you can find the best dog safe slug killers.

Stay Away From Metaldehyde

Metaldehyde is a common ingredient found in slug and snail bait. This chemical is very dangerous to pets, including cats and dogs. Metaldehyde can affect your pet’s nervous system and cause death.

These baits often contain molasses to attract slugs and snails. Your dog won’t be able to resist the sweet smell and will want to inspect the bait.

Get Rid Of Slugs Without Endangering Your Pet

You can rid of snails and slugs without using baits with metaldehyde, which can be dangerous for pets and children. Start by manually removing all the snails, slugs, and eggs you can spot to slow down the infestation.

You can also plant lavender, mint, rosemary, and other companion plants that keep snails and slugs away.

Diatomaceous earth is another way to keep pest away. This is a soft sedimentary rock that naturally keeps insects and parasites away. It is non-toxic to animals and humans and works against many different types of pest.

Beer traps and grapefruit traps are other efficient ways to get rid of slugs. The beer or grapefruit will attract the slugs, and they will either drown in the beer can or get stuck inside of the grapefruit. You can leave these traps overnight to get rid of slugs, but keep in mind that your dog might ingest a slug or some of the beer if you leave these traps out while your dog roams the yard.

The most efficient pet-friendly slug killers are iron phosphate baits. Iron phosphate is just as efficient as metaldehyde except it isn’t dangerous for dogs.

Is Iron Phosphate Entirely Safe?

The answer is no. However, it is a lot safer than metaldehyde. Iron phosphate works by damaging the stomach lining of slugs and snails.

This chemical doesn’t seem to have the same effect on animals and humans, but ingesting large quantities of iron phosphate can lead to iron poisoning. Using iron phosphate bait in your garden shouldn’t be a safety hazard since quantities won’t be large enough to pose a threat to animals or humans.

It is still best to monitor your dog around the slug baits and to make sure your dog is not eating the pellets. Leave the bait overnight and take them away in the morning if you are worried about your dog eating them. Watch for signs of iron poisoning in your pet, including vomiting and diarrhea.
