 2. Rodenticides

The rodenticides come in solid form and are commonly use with baits. The best rodenticides to use are the products that contains second-generation anti-coagulant – Brodifacoum, Bromodialone, Difenacoum, and Difethialone. These ingredients have an extreme effect on rodents that will kill them in one single feeding. But you can still use first-generation anti-coagulant – Warfarin, Chlorophacinone, and Diphacinone.

The length of time it can last depend on the number of rodents you have at home and the position where you place it. If you place it on the main entryway of rodents, you need to refill it every 12 hours or 2 days.

The only downside of rodenticides is it can harm your pets and other wildlife as well. To avoid harming your pets and other wildlife, you need to place it somewhere they couldn’t reach. Also, dispose of dead rodents immediately. This is because once wildlife eats the poisoned rodent, they will be affected by the poison as well.

If you have no idea about the exact place where the rodents are residing in your home, it’s recommended to call a professional pest control specialist. They have the experience and equipment to locate the main location of the rodents. They also use a specialised chemical pest control treatment that can eliminate all rodents in one spray.

Whichever pest control treatment you use for rodents, always make sure to seal all the holes in your property. This is to ensure rodents can never enter your property.

Pest control treatment is effective in eliminating the pest. Unfortunately, it can also do harm to people’s health. To ensure the safety of the family, you need to always read the label instructions. You must read the toxicity level (slight, moderate or high) and the label warning (caution, keep out of reach of children, and dangerous poison) if there’s any.
