Sentomol is located near Monmouth, in the county of Monmouthshire on the Wales-England border. The town is famous in having the only remaining medieval fortified river bridge in Great Britain; as the birth place of King Henry V of England (1386-1422); the home of Charles Stewart Rolls (1877-1910) co-founder of the Rolls Royce car manufacturing firm; and as the world’s first Wikipedia town.

Monmouthshire is an agricultural county with an abundance of crop and livestock production. Bordering the apple and fruit growing counties of Herefordshire and Gloucestershire, we appreciate nature and the changing seasons and understand the challenges in dealing with insect pests on a daily basis.

A little bit about insect trapping and monitoring

Agriculture, horticulture, livestock and food production is heavily influenced by the need to reduce pesticide residues and improve food safety. Similarly, the environments in which we live and work are subjected to stringent controls on pesticide use, to minimise their environmental impact and exposure risk. In addition, the increased scrutiny being applied by regulatory authorities to control pesticide use, has limited the portfolio of products available to both professional pest controllers and amateur home owners.

Insect traps can help professionals in using pesticides more responsibly and in residential and some commercial cases can replace pesticide use altogether.
