How to keep pests away from hot water system under kitchen sink?

[st22]

Vulcan under kitchen sink, usually warm, cockroaches reside in large numbers. They die of bait but happily come back a few weeks after. Any tips how to make this place uninteresting to them?

Thought of sealing the cupboard where the vulcan sits - would it be a fire hazard - like eliminate all holes & put something pest proof on the door

Hi @st22,

You can cut the old foam with a knife or a saw. As opposed to cutting away all the foam already filling the holes, I'd recommend concentrating on any spots that aren't currently filled.

 that is two before photos, if you have tips please let me know. For now, aiming to silicone seal these narrow gaps

and concerned about this on the left side, heaps of completely unsealed gaps to the next cupboard

 thanks

Looking good @st22.

Silicone sealing those gaps is likely the best option, and I'd suggest expanding foam for the gap between cabinets. You're on the right track, remove debris > seal any obvious gaps > lay bates/spray.

Thank you for getting back to me. Messaged you my location. I hope it is ok. Please let me know which product to get. My search for 'pestxpert cockroach' on the website came with zero results. I can head to another store that is not nearest, if needed.

Thank you, Eric. Would spraying near the vulcan heating system suffice? The cockroaches also live near electronics such as laptops, modems. They even entered an empty carpetless room despite no food or moisture being present. Wondering how that could be handled. (Would avoid the bomb as we have a pet and do not anticipate washing all surfaces for a few hours before letting it in).

Hi @st22

I suggest using the PestXpert 500g Pro-Spray Crawling Insecticide Spray around the hot water cylinder. As for the empty room, I recommend using the same on all the corners of the room. However, if no one is using the room and will be unoccupied for the foreseeable future, I propose bombing the room to kill the infestation. Just make sure your pet does not enter the room.

Unfortunately, there must be a large source of water somewhere in the house that is causing the infestation to increase. My only other recommendation is to engage the services of a pest control professional.

If you need further assistance, please let us know.
