Rentokil FMS01 Mouse & Rat Gap Sealant Mastic,White

The product was delivered promptly. It is simple to use and (so far) effective. The metallic content should deter any nibbling.

Perfect for the job, although I wish it came it smaller sizes as I still have about 3/4 left and it's quite expensive.

Rats had pulled out an air brick. Brought a facia to cover it. Held in with this stuff. Year later still no rats.

Easy to apply and fill wall gaps caused by mices

Never used a sealant/gun before but was impressed how easy it was to use. The sealant was grey not white but no bothered with that, its done the job

Used lots of silicone or caulk sealants in the past and this was noticeable that due to its thickness it’s a real squeeze to get out. But mice can chew through almost anything that’s not metal so having the flexibility to fill quite small holes is a definite benefit.It seems to have some kind of metal looking filaments in it which I assume is what makes it unchewable so.Very happy with purchase. Intend to guy one more tube to finsh job. Coulour is definitely grey NOT white

I used mine in pantry to seal holes paired with metal mesh grid. You'll need a caulk gun and plastic glove or any tool to give a good finish, however is a bit fiddly compared to regular sealant.Has a distinct smell to it and it lingers for couple daysSays takes 48 hours to dry - definitely not it been 4 days now and still not full dried.It works on wood and around pipes, good for big and small holes.It says it has metal fibres in it, having used it I am not sure from a visual look if it is there but from touch it has a sticky feel and feels very different to other sealants like ones used in bathrooms and roofs.Great for DIY work

Excellent and easy to use. Smells at first but wears off within a day, don't let that put you off buying.
