The answer to 'DIY rodent control' is that with the right precautions, you can often handle basic rodent problems yourself. However, for serious infestations or difficult-to-reach areas, it's best to call in a professional pest control technician. Proper DIY rodent control involves sealing entry points, using humane traps, and properly disposing of any dead rodents.
Start by thoroughly inspecting your home for any cracks, holes, or gaps where rodents could be getting in. Seal these up with caulk, steel wool, or other durable materials. You can also use humane live traps to catch and remove any rodents, then release them far away from your home. Be sure to check and empty the traps regularly. Avoid using poisons, as these can be dangerous for pets and children. If you continue to have issues or can't locate the source of the problem, it's best to call in a professional pest control expert.
