## Overview

Neogen Havoc Attack Blocks deliver a powerful 0.005% Brodifacoum formula that kills rats and mice quickly—often after just one night of feeding. Designed for use indoors and within 100 feet of agricultural or transport structures, these all-weather pellets remain effective in wet or dry conditions. Targeting over eight rodent species, Havoc Attack ensures comprehensive control with strategic placement and tamper-resistant bait station compatibility for safe, professional-grade pest management.

## Description

Bait stations are mandatory for outdoor, above-ground use. Tamper-resistant bait stations must be used if children, pets, non-target mammals, or birds may access the bait. Havoc Attack Blocks can be used in wet or dry areas and may only be used to control the following rodent pests in and around man-made structures: House mouse (Mus musculus), Norway rat (Rattus norvegicus), Roof rat (Rattus rattus), Cotton rats (Sigmodon hispidus), Eastern harvest mouse (Reithrodontomys humuli), Golden mouse (Ochrotomys nuttalli), Polynesian rat (Rattus exulans), and Meadow vole (Microtus pennsylvanicus). This product must be used in and within 100 feet of man-made structures constructed in a manner so as to be vulnerable to commensal rodent invasions and/or to harboring or attracting rodent infestations. Determine areas where rats or house mice will most likely find and consume the bait. Generally, these areas are along walls, by gnawed openings, in or beside burrows, in corners and concealed places, between floors and walls, or in locations where rodents or their signs have been seen. Protect bait from rain or snow. Remove as much alternative food as possible. FOR RATS: Apply 4 to 16 Havoc Attack Blocks per placement. Space placements at intervals of 15 to 30 feet in infested areas. Maintain an uninterrupted supply of fresh bait for at least 10 days or until there no longer are signs of new feeding by rats. FOR MICE: Apply one Havoc Attack Block at each placement location. Space placements at 8- to 12-foot intervals. Larger placements (up to 2 ounces) may be needed at points of very high house mouse activity. Maintain an uninterrupted supply of fresh bait for at least 15 days or until there are no longer signs of new feeding by house mice. It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

## Customer Reviews

### ⭐⭐⭐⭐⭐ This stuff rocks!!!
*by Y***7 on October 16, 2024*

We tried pretty much everything that you can buy at Walmart and nothing worked. Then, I watched a few videos on YouTube and found out about this stuff. It worked great!!! Started finding dead rats within 24 hours. After about 4-5 days,we quit hearing rat activity. Yes,this stuff is a little pricey but worth every penny! I will definitely keep some around for future use.

### ⭐ Rats do not eat Havoc rat bait.
*by A***R on December 28, 2024*

I have used three types of rat baits.BEST: My own mix of peanut butter and a different brand of rat bait.OKAY: The BLUE rat bait in the photo is okay, not great.BAD: Havoc rat bait is terrible. It is the PURPLE bait in the photo. A waste of money. Ihave multiple rat stations and Havoc has never been touched by a rat. I have two trail cameras and notice rats avoid Havoc brand.

### ⭐⭐⭐⭐⭐ This Stuff Works
*by J***A on June 17, 2024*

We've been invested for a long time. I hesitated to use poison because of my pets, there is an antidote for this one. The rats are GONE!!! MY PETS ARE FINE....
