Methods of Mole Control

When moles are ruining your golf course or spoiling your crops, you have several different options for removing these pests from your property. At Ringwood Pest Control in Ringwood, Hampshire, we’ll go over your removal options as well as the pros and cons of each method. Let our comprehensive mole control services resolve your mole problems.

Requiring Approval

Chemical repellents are classified as pesticides, so only those with approval may be used. All approved repellents must have an HSE registration number clearly displayed on the product packaging.

Available Chemicals

The only approved chemical control method involves the use of aluminium phosphide, which comes formulated as a pellet. It reacts with the moisture in the soil to emanate phosphine gas. Aluminium phosphide is a Schedule 1 poison, and operators must be trained, certified, and assessed in order to purchase and use it.

Choosing Gassing

Gassing has limitations, and you must consider where it is being used, as it is not ideal for every situation, as you cannot use it near habituated buildings. It is most effective in clay or heavy soil as when used in sandy soil the gas is not retained long enough to be effective. Under normal conditions, phosphine gas will be liberated from the pellet for up to 48 hours, and moles will generally have travelled throughout their tunnel network within that time.

Gassing has become expensive, as the aluminium tubes containing the pellets have to be disposed safely through a licensed hazardous waste handler and records must be kept.

Pest operatives also have to register as low-level hazardous waste carriers and monthly returns have to be sent in for each waste category.


Although trapping is regarded by some as old-fashioned, it is also often the cheapest form of control. Although the traps themselves are relatively cheap, costing between £7 and £10, using them is labour intensive. Costly site visits are required and there are frequent losses from people pulling them up, the mole dragging them down, or machinery causing damage.

Under the existing legislation there is no legal requirement to inspect traps set for moles at any specific interval, however, humane and efficacy considerations should be taken into account. Any traps used should kill the mole as humanely as possible, meaning only quality traps should be used.

There are two main types of traps: the scissor trap and the half barrel (Duffus) trap, which is derived from the barrel trap developed for mole control 150 years ago. Humane live traps are available for use but in fact these are cruel, as the mole gets stressed and will often die as a result and relocating a mole to an area where they have no established runs will often result in starvation.

No Guarantees

Although trapping is often preferred, as it provides proof that a mole has been caught, it is important to be aware that another mole may move into the vacated set of tunnels as they will offer a ready supply of food. Therefore re-infestation frequently occurs no matter which method is used. For this reason we cannot guarantee against re-infestation after seven days without new hills appearing.
