What is the best rat poison?

At DIY Pest Control, we offer efficient and cost-effective solutions to your rat infestation.  With a range of options available to you, you should be able to easily find the perfect poison in the perfect size. We have compiled a short guide to help you weigh up these options to eradicate your unwelcome guests and control rats as quickly as possible

Block bait

Block baits are highly recommended because they are really easy to use, clean and easy to secure. Our rat poison block bait contains either 0.0025% difenacoum or brodifacoum. Block bait is designed to be used within bait stations, making it easy to place and specifically target your individual rat problem.

The baits are uniquely shaped, so that rats receive a lethal dose as quickly as possible, they are highly scented with a fragrance that is irresistible to rats and they have a central hole, so that the blocks can be secured to the metal rods that come with every bait station. 

Baiting using block bait and bait stations is the most responsible way to bait, because it ensures that the poison is kept away from any non-target species and is better for the environment.  Also, the bait is securable, so it cannot be dragged away. 

Block bait is available to buy in various sizes to suit whatever requirement you have.

3 tub price = £6.52 each

Ideal for:

  • Indoor and Outdoor Use.
  • Rat and Mouse Infestations.
  • Bait Stations.
  • Sewers.

Baiting tips:

  • Rats are shy of new things, so for maximum control, avoid tidying before baiting and once placed, avoid moving the bait boxes.
  • Use natural and familiar materials to protect the boxes, to encourage the rats inside.
  • Replace water damaged or contaminated bait every 2-3 days.

Loose bait

Our loose bait comes in handy ready to use sachets so it is really easy to place. Containing 0.0025% Brodifacoum or bromadiolone, sachets can be thrown into inaccessible places, where rats will readily chew through the packaging to get to the bait.

Loose bait is available in two sizes, 100g or 25g packs, the latter being the perfect size for an individual bait point. If preferred, sachets can be opened and loose bait used in bait trays or bait boxes, but as this leads to a high scatter risk, it is imperative that there are no non-target species in the area.

Rodex Whole Wheat Rat Poison

Rodex Whole Rat Poison comes in 150g sachets of whole wheat containing 0.0025% w/w bromadiolone. They are ideal for throwing into inaccessible places where they will stay dry until a rodent comes along, chews into the bag and eats the bait. Each pack contains 150g of treated wheat, enough to kill several rats.

1 pack price = £9.06 each (5 sachets)
3 pack price = £25.56 each (15 sachets)

Baiting tips:

  • Ensure that bait points are safe and there are no animals or children around who might consume the bait

Pasta bait

Knockout Rat Killer Pasta is a non-professional use product for the eradication of rats and mice. It contains 0.0029% w/w Difenacoum and is designed to be secured inside rat bait boxes. Each sachet contains a single 15g dose and has a fluorescent pigment within it, making rodent droppings visible under UV light, so easing the monitoring of rodent activity.

Knockout Rat Killer pasta sachets can be used indoors or around buildings and is sold in boxes x 3.  It’s a nice clean option as it cannot be scattered like loose bait, and it’s less wasteful. The sachets are easily pierced to skewer onto rods inside bait boxes. 

The sachets are small, like a t-bag and they do a good job of maintaining the quality of the bait inside. Bait should still be checked every few days, and any damaged or contaminated sachets replaced with fresh.
